How to identify a problem with a computer. How to carry out diagnostics of the self-tapping computer? Meta diagnostic robots - ce

An important step in computer repair is yogo diagnostics. Age, first put the correct diagnosis, it is necessary to carry out a decongestion. I work to be able to qualify specialties, for some kind of computer support and professional service.

Significant faults are formed from the next stages:

1. Primary diagnosis.

This type of assessment of the practicality of the computer is carried out at the house of the deputy. Primary diagnostics cannot be repeated and can only be done in certain fluctuations. Here you can enter a good look at the computer and its components.

2. Hardware diagnostics.

This stage is directly related to the detection of zipped parts of the computer. Malfunctions in the robotic system can be guarded, as a component from the gateway is installed on the equipment. In addition, incorrect functioning may be caused by worn parts. There is another option that is added to the work - overheating.

3. Software diagnostics.

At this stage, there are pardons from robotic software. The stability of the system is assessed. The operating system of the computer is falling down, after the analysis of the causes of the software failure.

4. New diagnostics.

Based on the results of all types of diagnostics, the service engineer will make a verdict - the cause of the breakdown. If the weather permits, the repair will need a computer for help.

For any problems with the computer, do not try to get food on your own. Qualified diagnostics and professional repairs can only be completed by a specialist.

Primary diagnostics

Folding electronic-computing attachments, like a computer, may be the basis of the mass of microcircuits and other boards. It is obvious that the repair of computers by the forces of "amateurs" can be less in the community. To build standard repair robots will require theoretical and practical knowledge, as well as great knowledge. The first step is to proceed to the beginning of the engagement, the maistry to carry out the first step, and in folding steps - hardware and software diagnostics.

The primary diagnostics of the computer is used in the coming battles:

1. Superficial look at the software part.

Superficial software diagnostics can be based on re-verification of the practicality of the operating system, the correct functioning of the programs. Carried out at the house of the deputy by the forces of a service engineer without stopping the diagnostic control.

2. Superficial inspection of the apparatus part.

This visual review of the computer configuration and assessment:

Disk type;

A lot of memory and ability to win;

Pratsezdatnostі kom'yuternih pristroїv (nasampred zhorstnyh diskіv).

For the help of a superficial glance, it is possible to identify the low inconsistent malfunctions of the equipment.

Hardware diagnostics

The first task of the robotic service and repair of computers is diagnostics. As practice shows, more damage to practice and failures of technology was caused by a lack of regular prevention and diagnosis.

Meta diagnostic robots - tse:

Recognition of malfunctions of computer equipment;

Z'yasuvannya їhnoy character.

Hardware diagnostics is directed to the detection of mechanical (non-recognizable sounds) of various components of the computer.

Hardware diagnostics of the computer includes rechecking the temperature regime of the computer components and stability of operation:

Central processor;

Operational memory;

Zhorst disk;

Video adapter;

Chipset.

After carrying out any type of diagnostics, the client will take:

Sound about the camp of the hardware part of computer technology;

Forward rozrahunok tsіni on work from the usunennya of inaccuracies;

Propositions for modernization.

Timely hardware diagnostics of the computer can significantly change system failures. As long as you don't show a problem at an early stage, your technique may be completely paralyzed.

At a glance, as a service-engineer, it is necessary to replace the parts and repair in order to restore the efficiency of the computer.

Come in hardware diagnostics to allow you to carry out the necessary repair work, improve the efficiency of technology, and improve your code. Tse same vpadok, if you allow yourself to avoid serious problems.

Software diagnostics of the computer - the detection of a defect that yogo viniknennya. With whom:

A review of the operating system is carried out to improve the stability of robotic computer technology;

Perevіryaєtsya navantazhostіykіst okremih koremikh komplektuychih that kom'yutera in a whole;

Testing the feasibility of the mother board with different special modules.

The amateurish pidkhіd to the process of melting at oneself is lowly unsafe. For example, in case of a malfunction of the mother's payment, the coristuvach її zminyuє, not wondering about the causes of the breakdown.

Computer diagnostics on the software level is needed, as follows:

1. Technique does not fit in.

2. Independently vimicate.

3. The computer freezes.

4. Rezavantazhuetsya for no reason.

5. Pratsyuє povіlno.

The software diagnostics of computer technology includes:

1. Superficial look at the software part.

2. Computer software testing, which includes:

Rechecking the file system for pardoning;

I will recheck the registry of the operating system;

Review the visibility of critical OS updates.

Povna diagnostics

Diagnostics of the computer, or the determination of the causes of the filthy work of the fault, is carried out by qualified fahivtsy. As practice shows, it is not enough for professionals to overcome the low number of typical problems in robotic computer technology.

For the help of new diagnostics of computers, it is possible to detect malfunctions and install the possibility of modernizing technology.

This type of diagnostic work is only done by qualified service engineers with specialized expertise and includes a few steps:

1. Superficial view of the master of the software part of computer technology.

2. Computer software testing for additional special utilities.

3. Superficial view of the master of the apparatus part of the technique.

4. Testing of additional components of the hardware extension.

5. Testing of the main components of the hardware building.

New PC diagnostics included, go to the test:

Software security and operating system;

Mother's pay;

processors;

Zhorst disk;

memory slots;

attachment for reading information (floppy disks, drives, card readers);

TV tuners, wired and wi-fi, modems;

Video cards;

Lanzyug, to the block and controller of life;

Monitor.

The mustaches of personal computers are guilty of memory: they carry out the diagnostics of the varto regularly, without checking, the docks of the technician will give a good answer. In this case, your PC will serve you for a long time, but if you need to repair your computer, you will not replace the components.

First of all, I don’t think we’ll take a look inside the system unit of a typical computer, to find out what is installed there. Do not hurry to unroll your system, but to turn on the internal attachment of the computer on the base level of the statistics:

1 - life block, 2 - motherboard, 3 - processor, 4 - memory, 5 - video adapter, 6 - hard drive, 7 - optical drive

Mustache manipulations. as will be described in this article “how to diagnose a computer” if I add a “typical” system unit, your computer may not be described here, so you are not sure that you correctly understood the sensory data and yogo result, do not work on your own everyday manipulations. All the procedures for selecting and folding the system unit are described in the article “How to perform computer diagnostics” can only be carried out on the POVNISTTI to the unscrupulous owner. The author of the article "how to diagnose a computer" does not bear any guarantees for your findings and results.

how to run computer diagnostics?

And now for the quiet, who is not snarky and to whom we can spend nothing.

Diagnostics of the computer starts with the inclusion, tk. all the switches on the computer behave the same way, as in the right way it can't. To turn on the system unit, we are responsible for reversing whether it is connected to the right power outlet, which is connected to the operating range of the live unit, on the live unit, the transfer switch is set to “on” or “on”,

Mayte on uvazі, scho on some blocks of life vimikach vіdsutnіy, then it is enough that before the new insertion of the cable of life

on the front panel of the system unit, we press the Power key and check it ... So, what can it be, if the right computer is connected? The voltage supply indicator is to blame (usually a green “light”), the cooling system fans vibrate on the start, the test installation is performed on the motherboard and everything that is connected to it and you can see the result of diagnostics at a single squeak of dynamics, which means everything is turned on fine".

Just not our type. Due to the presence of malfunctions, the block of life in the fallow stage swells when pressed on the Power button, most of the time nothing is displayed (the computer does not turn on), otherwise the light of the life lights up, but the fans do not make noise and the diagnostics do not pass. the sound is quiet. From here we need our tool. We turn on the system block in the direction of the fence, turn it back to the “fox” in front and twist two screws on the right side of you krishtsi, then we pull it on ourselves and take it. If you don’t have a typical hull design, be aware of the instructions on how to install it, everything is to be blamed without overhead zusil. Now all the insides of the system unit are in front of us. For the convenience of carrying out the remote systemic block, it is necessary to put it on the biktoy side of the hill. It is known that all the darts converge until such a “tight” look, this is the block of life, the call to the new one is connected to the cable of life, I am contagiously wound up. It is verified that all the roses are superficially inserted, inserted to the “stop” and do not have backlashes, as if the non-contact is shown usuvaemoly, having firmly pressed the z'ednannya, you may need a susilla. Connect the live cable to the place and robimo re-test the inclusion. If you change the days, then it is necessary to turn on the life and start by turning on the life block for further diagnostics. To raise respect, which roses, which are connected to the mother's board (the largest board in the computer), to make braces, as it is necessary to open the braces in front of the roses, to shy away from pressing on the upper part of the blot. Pohituyuchi roses from the side on the b_k is heavy for the nest, like a zasuvka v_dkrivat, then the roses are guilty of going out of the nest. Then, in the future, there are plugs to storage devices: a hard drive and a drive, on older computers you can still connect storage devices FDD 3.5 "on these roses there are also drawers, so do not pull hard, do not open the drawer.

We drop the BIOS and test the motherboard

Now it's time for the motherboard of the processor. You can see the motherboard interface cables IDE (wide flat 40-80 core cable), SATA (red, yellow or black, about 1 cm wide), fan life, which should stand on the case (the processor fan is left plugged in), vіdkrivаєmo tucks to trim the board are installed in the roses of the mother's board, we remember the memory of the trimming of the memory in the back of the module and it's heavy on itself. Axis mi mayzhe rozіbrali kom'yuter. Scary? Yet, at the same time, the most important moment, if you don’t become a diva, repairs can be even more expensive. Now it is necessary to add a total of two roses to the block of life to the motherboard: the main 24-pin and 4-pin auxiliary processor. There is no need to connect more than anything, after which you connect the cable of life and robably try to turn it on. If you sensed other signals from the dynamics of the motherboard, then you were spared, there is a chance that everything is not so running, the motherboard and the processor have gone up. although it doesn't mean that the stench is absolutely correct. For those who have started the processor fan, but quietly quickly, try to reset the BIOS settings in the factory. I shuffle a battery on the motherboard, I go for a coin of a bright color, with a diameter of 18-20 mm, and next to it a jumper with a JBAT signature, if you don’t know this, remove the book of the mother board and look for the Clear CMOS partition, there is a switch for the buti flash BIOS. As a rule, the jumper is to be left in position 1-2, and in order to reset the setting to zero, it is necessary to transfer it to the opposite position, for example, in 2-3 and for a short time the system unit is turned on for 3-4 seconds, and then turn it off. After that, turn the jumper in the cob position and try it again. As soon as sound signals appear, you can step by step folding the system unit. Otherwise, we have lost the rest of the chance, reconcile, without losing contact with the processor socket.

Selectable from the processor(how to run computer diagnostics)

For which we need to take a fan from the processor at the same time from the radiator. Processors Intel and AMD may have different systems for mounting the radiator to the processor. In the case of Intel processors, which can be used for roses S775, S1155 / 56, we will need a flat twist and we will need to turn the anti-Year arrows 90 degrees on the plastic tabs, like trimming the radiator. Because of what wine is guilty of viynyat z small zusillyam. In the case of the AMD processor, it is necessary to turn the valve upside down, on one side of the radiator by 180 degrees and loosen the plate, after which the buckles are pressed, which will reduce the radiator at the pressed position and take the radiator. From one side of the rose, there is a metal important pressing the processor to the rose, it is necessary to press the processor firmly and re-fix it on the plate. Sometimes blame the non-contact of the processor at the roses, so that you can use it. The design of the processor cooling system may be different from the standard one at this time, you should be aware of the instructions for installing your processor cooling system. In order to add some residual visnovok about the unpracticality of the mother's board, before it it is necessary to connect a svіdomo living block and a total working processor, as if the self-diagnostics of the payment “move”, then the reason itself is in nіy. As soon as the mother's payment is transferred 5 years, then more often you will be generous for everything, not only to replace the mother's payment, but also the processor's operational memory, if you want the option with the mother's motherboard used can be proponuvat.

Insert memory and video card(how to run computer diagnostics)

We suspect that after our manipulations, self-diagnostics worked and you felt a “permissible” squeak about those that the motherboard showed the daily memory modules in roses. The time has come to put them on the table. Even if the memory modules are covered with a saw, then it’s too bad to see and prostozhite, so that they won’t waste it to the nest for the memory modules. The contacts on the memory modules can be cleaned with an additional large buzzer, as there are particles of brud stuck to them. Just be careful not to scratch the electronic components soldered to the module with a gum and carefully look at the memory module itself, as there is no trace of the next component or overheating. In order to install the memory in the place, it is necessary to spread the module to the sides of the brace, so that the slots on the modules zbіgavsya with a ledge in the middle of the rose, put the yogo into the clasps and press it simultaneously from two sides to the nest, so that the clasps are closed. Let's turn it over like a schіlno uvіyshov the module at the roses and there are no backlashes. Avoid overworld noise when installing modules, so that you do not bend the motherboard out of the world, otherwise you can blame internal cracks in the electrical paths of the board, which will lead to її impracticality. After the modules are installed, the system unit is re-installed. It may change in the nature of the squeak of pay. If you sensed a new sound for a long time and three short beeps, or one for a long time on board the motherboard is a video adapter, then there may already be 4 potentially correct components: the life block, the motherboard, the processor and the memory. If you felt silence after installing the memory, or the nature of the sound signal did not change (a long squeak, which is repeated), then the memory is not practical and must be replaced. Try to install the module in a different rose, or change the order of the installed modules, otherwise such an operation may not give anything. After the memory is installed, it is necessary to insert a video adapter on the plate, either AGP or PCI-E 16x, if necessary, connect an additional power supply to the video adapter (8- or 6-pin roses), on the monitor. As soon as the video adapter is installed, the signal on the monitor does not appear and the nature of the sound signal may "look" for one long three short periods or it is completely silent, then the reason for the failure is greater than for everything with the video adapter. If you have the same problem, if you have an adapter and a reasonable payment, then you can turn the computer's operation without connecting it to the wrong order.

Let's hope that the image nevertheless appeared and we can proceed step by step to select our selection system. If you know about the memory of the memory modules and their general knowledge about what the BIOS test program wrote, then we are on the right track. For example, if the BIOS has run out more than half or more than one module, it means that the module is counted, the volume of which is not visible, with a path of handwriting memory modules. Just do not forget to use the computer before any manipulations. Do not remove the non-working module from the motherboard, replace it with a new one, the sum of your motherboard, or continue to work without a new one, so that if you lose it, you are in power.

Connected storage(how to run computer diagnostics)

And we are moving to the offensive stage of selection, connection of accumulations. Accumulating hard disks on a hard disk or common people - "Winchester", buy decal standards, most hard disks are upgraded to the SATA standard or IDE. Visually, they can be adjusted according to the width of the rose for connecting the interface cable: IDE wide 40 pins, SATA - a small rose of about 12 mm in a seemingly curly letter G with 7 pins on the bottom. Next to the interface rose, there is a rose for connection to life, a 4-pin straight-cut socket with two cut-outs in the IDE standard and a flat, rich-contact similar to the interface, only extended (23 mm) in the SATA drives. Plug in the need for roses, the interface is connected to the cable leading to the motherboard, the roses to the power supply rose. Two attachments can be connected to the IDE interface cable, but if you need to configure additionally, I will add an additional jumper, which is in charge of the interface rose, here I can’t see the topic, so you didn’t change everything in order, then everything was changed in order you need to insert the cables in roses so that the stench of the boulevard was taken to the point of separation. All the above said about hard disks is fair and optical drives. After connection, it is necessary to turn on the computer and check whether the BIOS of our devices is indicated. For which it is necessary to enter the BIOS by pressing the DEL keys for the hour of the computer’s vanity, go to the branch Standard CMOS Features or MAIN, in staleness in the form of the bios program.

The lighting rows show how you can see the record about the songs of the disk attachments.

The lighting rows show how you can see the record about the songs of the disk attachments. Just name the add-ons that may be installed on your computer. If there are no records about disk attachments, it may be evidence of the failure of the drives of either disks, or the failure of interface cables, such as plug-ins. Varto reverify once again the strength and supremacy of the connection of roses of life. The hard drive, when turned on, is to blame for seeing the inconspicuous high sound of the engine, which spins, when you put your hand up to a new one, there will be a slight vibration. When giving live, the optical drive is to be blinked with a light od on the front panel of the extension. Vidsutnіst a sign of the supply of live is also a sign of the inaccuracy of the drives. For those who have discs, the extensions have been assigned correctly.

The hour has come to try to get a computer. If the reason was in my non-contact, then after our procedures, we could have lost it. If the advancement was successful, then on which one you can fix it, but for those who have a problem due to the advancement of the OS, the option to check the offensive statistics, about the software diagnostics of the computer, has been lost.

Diagnose the computer yourself. Be sure it's unacceptable if the computer goes out of tune. Until then, it often happens in such a way that it happens at an inopportune moment. But then you should understand that the type of technology you need cannot be perfect for the whole hour. So chi іnakshe, without breakdowns can not be done.

Ale, not everything is so bad, even a computer can be repaired. But firstly, take care of yourselves, it is necessary to perform diagnostics in order to know the cause of the malfunctions.

The first thing you can shut up with is the computer can't be turned off. It may be due to various reasons.

Problems are divided into 2 types:
software type of problems;
malfunctions at the "Zalіza".

Insignificantly, the breakdown has become de same, it can be an offensive rank.
When the computer starts to turn on, notifications will appear on the screen. No one has a chance for a pardon without intermediary in the operating system. Tse means that she has a problem herself.

First of all, it is necessary to start, to get started in the safe mode by pressing the F8 key. Next, start the "System Renewal" function for an early period.

Like a computer, like before, it doesn’t work, you have to reinstall the entire Windows system. At the service center, de vibration laptop repair work is not so easy.

Well, because of this situation, a black screen with all indicators (motherboard, cooler on the processor is in the working state, and Windows is not working). In this case, it is necessary to change the system block.
It's easy to do this: look at the HDD indicator light. It’s all right, but don’t just use a monitor. You can just unplug and replug the cable.

Another problem is when the indicator does not light up. Whomever has a chance to change what the darts are getting into, as well as all the outbuildings. This is a video card, a life block, and a hard drive. For which the wall of the system unit (bіchna) is used.
Naygolovnіshe, scho need to grow, take out the RAM and put it in another slot. If there are 2 or more planks, then you can replace them with each other.

As if, as before, nothing is seen, then a little farther away - the return to the service center.

About the problems with the block of life, note the following signs:
the computer is mimicking and independently repairing the reset;
sharply begin to "hang".

You can also say the same about those that the component is overheated. Call the processor, or the video card.
On the problems with the video card, there are also signs - the rapt is on, the screen is turned off, the image is defective (the color changes according to the individual).

In such situations, the computer needs to be cleaned (mechanically, like a saw).
Sometimes, in case of problems with the life block, the PC can turn on by itself, if a voltage is applied.

If it’s for a change, if the cause of the breakdown is not fully explained and there is no fault in the divisions, then it’s better to go to the service center.

Problems with a desktop computer can have different causes. Dotrimyuyuchis our pleasures, you can quickly swallow the injustice.

Exit the PC from the fret can be different. For example, after pressing the button, the machine does not give a sign of "life". Either the computer is running, or the other components are not functioning. We have been told next, what is still practicable, and what is not. Why burn the light of the mother's pay? Chi spinning fans? Is there an image signal on the monitor? What are the BIOS prompts showing? On the basis of these warnings, most problems can be divided into six categories (div. below). For the skin category, we suggest instructions that are added up from the last steps, for the help of which you can turn off the possibility of the simplest malfunctions, so that we can then proceed to more complex diagnostics. If you haven’t achieved success in any of the stages, go to the offensive until you solve the problem. Learn how to learn on some crochet, the results of your testing will become a handy help for practitioners in the service center.

1. No sign of life

As if the computer does not normally react to the pressure on the button, in the first place, the next step is to change the button. We will help you to localize the problem.

1.1. LOOKING LOOK. Persh for everything, turn over, what good connections are made to the cable of life and what is added to the mesh filter. The situation is not turned on if the button for the life block on the right side of the computer is at the “Wimm.” position.

1.2. CONNECTORS TO THE BODY. Look at the PC case and reverse the head of the connector and the width of the cable on the spacer between the switches and the light diodes on the case and the motherboard - it is possible that the connector is in the middle of the plug. Just one or more cables are out, check the helper to the mother's board and turn over, which cables are connected to the plugs.

1.3. SHUT BUTTON. If the connectors to the case were connected correctly, otherwise re-connecting did not give a result, remove all the connectors from the motherboard. Let's close two contacts with the Power Switch writing for an additional violin. If the computer is mentioned, there are two possible options. First - the power button on the case is faulty. In this case, it is necessary to connect the connectors with the inscription "Reset Switch" to the contacts with the inscription "Power Switch" on the motherboard. From the first moment when the PC is turned on, it is necessary to use an additional reset button, and the power button will stop its function. Another reason for such a malfunction may be a short flicker in the reset button: the primary button in this case is not practical, and starting the PC will only be possible by flickering two contacts on the motherboard. Confirmation of which permission will be possible to start the PC with the reset button disabled. At this time, leave the connect button, and disconnect the reset button. After all, your PC, better for everything, will turn on again without any problems. Even when violating the office violin, the computer is forced to "start", then reverse the living system.

1.4. LIFE OF THE MOTHER'S PAYMENT. Reverse the correctness of the connection of all connectors in the living block to the motherboard. There is not only a wide ATX connector with 24 pins, but also an additional P4 connector for the life of the processor.

1.5. LIFE BLOCK. Gave it necessary to turn off the possibility of exiting the operation of the living unit. For which connection to the PC, refer to the PSU, for example, from another computer. Connect the 24-pin ATX connector and either or the eight-pin P4 connector of the right computer to the motherboard of the faulty PC and try to run it. As soon as the next wine is noticed, it means that everything on the right is in the block of life, which you will need to replace.

1.6. MOTHERBOARD. Even though everything described above didn’t help, then, more for everything, the motherboard was in order, it’s better to replace it, but the repair is not guaranteed, as a rule, it’s not true for yourself. So chi іnakshe, the replacement of the mother's payment means outside the disassembly of that folding of your PC. However, it is recommended to start the procedure at least once, if other possible faults are excluded.

2. PC works, but no image

When the screen is turned on, it turns black, if the fan of the power supply unit is turned on, the CPU and video card work and the LED on the system board lights up.

2.1. MONITOR REVIEW. It is necessary for us to turn off the banal injustice, turn on the power supply: why turn on the monitor? If not, then, perhaps, there is a problem with life: the cable is plugged into the display or into the socket, or the screen can be switched off, which is set to the “Wind.” position. When the monitor is turned on, open the on-screen menu and turn it over to make sure the correct signal is selected (VGA/D-Sub, DVI, HDMI).

2.2. SOUNDS AND LIGHT SIGNALS. If the monitor does not send an image signal, the motherboard will often let you know by beeping and light signals, which will allow you to figure out what the problem is. Return to the helper of the mother's pay, to determine what the signals mean. One of the typical defects, which are reported in such a way, may be incorrect or incorrectly installed RAM modules, or the system board, if the model is out of date, ahead of the additional sound signal or the light lamps that burn.

2.3. RESET BUTTON. Short buzzing of the reset button can also be the cause of the symptoms. Check the revision (clause 1.3).

2.4. BIOS. Sometimes the cause of such problems during startup may be incorrectly configured BIOS. To reset the BIOS parameters, find the Clear CMOS jumper on the motherboard. There are three contacts, two of which are connected by a jumper. Remember the position of the jumper, then pull it out and connect another couple of contacts with it, check it for at least ten seconds. After that, I will set it up again at the exit position. Also on the system board there is a reset button, press її. If the computer is disabled, reset the BIOS. For more options, you need to select the correct mode for the SATA controller, like, for Windows XP, є AHCI, not IDE. If the problem is assigned, it may arise. One of the possible reasons for the BIOS to be messed up is that the battery of the system board has run out - about the same in paragraph 3.1.

2.5. OPERATIONAL MEMORY. Most motherboards signal about faulty memory for additional sound or light (LED) signals (div. point 2.2). However, we recommend that you check the timing of the operative memory modules without checking the signal ahead of time. The computer has at least two modules installed on its own - install one and try to get the computer started. If the PC is not connected to this module, try to start the system with the installed module. If the computer starts with less than one memory module, that means that another one is faulty.

2.6. VIDEO PAYMENT. Among the components of the PC, the problem is faced by warto shukati at the jereli signal of the image - a graphic card. If your computer is equipped with a built-in video card, use a discrete board and test the system with a built-in GPU. In a different way, I'm turning it over, which PC works with another graphics card. So, your discrete or built-in video card is faulty.

2.7. PROCESSOR. A faulty processor can also cause the computer to work but not see the image signal. Therefore, protest as much as possible before the upcoming folding cycle of the production of a PC with a smaller sum processor.

2.8. MOTHERBOARD. In response to those that all other possible problems are now turned off, the rest of the “suspect” is left behind the motherboard. The problem here may be, for example, in the CMOS chip, in which the BIOS is saved, or in the PCIe bus, to which video cards are connected. Poshuk that osunennya inaccuracies in the most vipadkiv do not lie to yourself, then the best solutions to immediately replace the system board.

3. BIOS attaches to the robot

The BIOS manager is responsible for preparing the computer to take over the operating system. If problems are blamed in the process of BIOS robots, then you will hear about pardons, for the help of which you can localize them.

3.1. BIOS SETUP. With computers that have released chotiri-five years ago, situations often trap, if the stench of the znenatska is driven to be zavantazhuvatisya. The reason is BIOS tweaks. This way it says "Please enter Setup to recover BIOS setting" | CMOS Date/Time Not Set". You can enter the BIOS, as a rule, with the help of the F1 or Del button when the PC is turned on. For this reason, it is necessary to specify all the main settings, for example, the date, the sequence of advanced devices, or such an important parameter as the mode of operation of the SATA controller (AHCI). After the introduction of the problems caused by the problems of the PC, it is not the fault of the buti. However, the reason why the patching was broken, crying, more, in the offensive: on the system board there is a round flat battery, like an “emergency” CMOS lifeline, so that the rest does not waste the patching. If the battery is low, you must replace it, otherwise the BIOS settings will crash when the PC is turned off.

3.2. HISTORY OF ADVANCED APPLICATIONS. Just like the BIOS tells you about those who can't know the most interesting one, there may be a few reasons. For the cob, turn over the sequence of lucrative outbuildings at the installations. In modern system boards, for which it is necessary to have two operations. You will find the item "Boot priority" in the parameters of the advancement, in which case such components are indicated, such as hard disks, changeable media or optical drives. The hard disk is responsible for the mother's highest priority of vanity.

3.3. Disk failure. If the drive doesn't show up in the BIOS media selection menu, check the PC and check whether the power cables are connected or not. If the problem persists, test the drive with another cable, HDD enclosure with USB interface, or another computer. Even if it doesn’t help, then, nayimovіrnіshe, nosіy viyshov z fret in the aftermath of the controller’s fuss. In this way, give a tribute, better for everything, maybe less fahivets for a few pennies. As you regularly create system images and backup data, you will need to replace the disk and back up the data. In another case, you will need to reinstall the system again.

3.4. EXCELLENT SECTOR. Even more exciting attachment is displayed in the BIOS and you can look at it when you connect to another PC, then, better for everything, the sector of interest has been disabled. It is often worth dosing when trying to re-distribute disk space, or when Linux is remote, which wins out like a different operating system. To get a pardon, get yourself from the installation DVD-ROM or the emergency notification disk. In the process of interest, select "Computer support" or "PC update options", then click "System update", and then finish the master's window. If it didn't solve the problem, try the manual update. Start the computer again, as described above, and open the command line window in the settings of the renewal system. Enter the following commands for the new one:

bootrec /fixmbr bootrec /fixboot

bcdedit ;/export C:\bcd_1 c: cd boot attrib bcd -s -h -r ren bcd bcd_2 bootrec /RebuildBcd

If so, Windows may be zavantazhitisya. Even now they are blaming difficulties, read the instructions below.

4. Unable to capture the OS (there is a Windows logo, but the system does not start)

Your computer starts to become zavantazhuvatisya, but before the appearance of the core interface "freezes". With such symptoms, you can turn off silent problems with the possession of the BIOS.

(more will be)

It is not uncommon to trapleyaetsya, that after a long time working without failures, the computer must not go out of tune. In tsimu, show breakdowns and yogo causes can be even more different. Whether it's a fluke in the middle of the night, it's the fault of the computer's diagnostics on a malfunction, to understand which element of the PC is to blame for the malfunctions.

PC won't turn on

As soon as the computer does not respond after pressing the button, the computer does not respond, it is still a life problem. The simplest way is to move out of the way of the button itself.

looking around

It is not uncommon if the jumper on the rear side of the life block is set to the "Vimk." In this case, the solution of the problem will be the simplest.

Conectory

Even though a smart looking glance did not bring results, further diagnostics of the computer on faults and folded data. Remove the cover to the case of the system unit. Don't forget to turn the computer off in front of the fence.

Wonder if you didn't see the connectors in the motherboard. Best of all, turn them on, wipe them with alcohol and cologne. Then we will be brought to the point of kerivnitstva, as if we will work together from the mother's board. It will be assigned to the new one where all the darts are connected.

By a similar approach, it is possible to include a number of possible causes of a malfunction: oxidation of contacts; incorrect connection of darts; vipadkovі rasrivi in ​​lanceuzі.

Button

Even though the previous steps did not bring results, computer diagnostics for malfunctions can be continued after the connector of the button is removed. As you can remember about the robotic process, you can connect up to two contacts to the motherboard. To close them, be a kind of metal object, for example, a clerical violin.

As soon as the last PC was noticed, it was better for everything, the button was broken. In order to get rid of the inconsistency, to address the problem, you can simply change the meaning of the "Reset" key by connecting a wire to the "Power On" connector on the motherboard. Tobto to the fact that the closures of the violin earlier. Now, to start the PC, you will need to press the reset button on the system block.

Another possible error with the same symptom is the "Reset" keys. To change the diagnosis, just turn on the wire that the reset button appears, and then try to turn on the computer in the usual way.

Problems eating

Even though the paperwork did not help, even more so, the mother's fee does not take away the necessary food. In some cases, computer diagnostics for malfunctions can be continued by rechecking the ATX and P4 connectors.

ATX - not a wide rose, I have 24 pins. P4 may have the shape of a square, and to the new one go chotiri droti (one and the same number can reach eight). Just turn it off, and then I will reconnect with roses.

Living block

Even though the front steps did not lead to a positive result, it’s good to see BP, but the imovirnist of this is not stovidsotkov. Further diagnostics of the computer in the home minds is connected with the help of the living block to the PC.

The simplest vikonatsiy item, as you have a small computer in your house. Otherwise, you have to go back to the service center. Buying a new PSU for diagnosing problems is not the best option, even if you can fix it, and the problem manifests itself through other problems.

Motherboard

After replacing the block of life, the computer does not get in? We can boldly say that at the time the diagnostics of the computer bay is completed, that is how the motherboard came out of the way. It is best to replace it again, the repair of similar equipment is not true for yourself, because the price of the procedure can be higher, lower than a new one.

Problems with robots

Even if the problems are not blamed on that unsystematic same hour of work, computer system diagnostics can begin with updating the most important software. Until then, you can save the OS, drivers, antivirus. Although no annual expenses have been installed, we’ll perform the installation, and then we’ll scan the computer outside for viruses.

RAM

Quite often, the stability of a PC robot is destroyed due to a malfunction of the operational memory. For її reverification, there are a lot of supplements. However, Memtest86+ is the most important. Zavantazhiti and vikoristovuvati її can be absolutely cost-free.

Before testing, it is necessary to prepare a flash drive.

1. Get the software distribution kit. At this stage it is important to choose the USB INSTALLER and not the ISO image.
2. The next time you start the wicking file. Its extension is EXE, and it's based on "Memtest".
3. It will appear on the screen, as a request, you will be welcome with the points of the license area. If it is not possible to start the program without confirmation, then press the "I Agree" button.
4. At the next stage, it is necessary to select a USB storage device, for which the program data will be copied. Be careful: all information from the flash drive may be forfeited during the installation process.
5. Now you have to click on the "Create" sign. Check if the program for computer diagnostics completes the installation, and then press "Finish"

Now reboot your PC and go to the BIOS. For which it is necessary to press the "DEL" button, if the computer is only a little bit more accessible. After starting the BIOS utility, go to the "Advanced" menu. For the new one, select the item "First Boot Device" and switch the parameter to "USB".

Restart the computer again. If all the forward points are correct, the computer diagnostics program will be confused. Rechecking operational memory can be opened automatically. Be sure to follow the instructions on the screen, sometimes before the test you will be prompted to follow the procedure in the safe mode. For this mode, you need to press the F1 button to start it.

Memtest86+ counts 11 tests. When the next time the rest of the procedure is completed, the back of the head will open up. As soon as the pardons in the RAM will be found, on the screen of the monitor there will appear a red area with its description. In case no problems are found after rechecking, the program will display the "Press ESC to exit" prompt screen.

As soon as the test hour was over, pardons were revealed, the operational memory should be replaced. Like slats of RAM, diagnostics and repair of computers are carried out by rechecking the skin okremo. For which it is necessary to install them in the system block by calling, and then change the Memtest86+ utility again. By fixing the broken attachment, you can continue to beat the computer without it, spending a little productivity, or turning off the crash.

Cooling system

Although the problems are blamed for the hour of work and resource-saving supplements, it is high that the PC cooling system is not efficient enough. Problem posilyuє drank, scho sits at the radiators. As a result, the sweat of a cold wind, which is blown by a fan, becomes suddenly blown over all the metal parts of the heat exchanger.

For the display of overheating, a program can be used. Diagnostics of the computer on a malfunction in the case of any vimagatim in the form of a corystuvala is no longer installed in a special program and watchful for the indications of the sensors.

AIDA64

One of the best utilities for monitoring computer temperature is AIDA64. After starting the program, it is necessary to select the "Service" item from the top menu, then - "System stability test". A window with graphs will appear on the screen. They show the temperature of all the main components of the PC.

After clicking on the "Preferences" button, you can independently select the data of any sensors will be displayed on the diagrams. It is not possible to run diagnostics on the computer if it is not possible to overheat, if the computer is in mode, then run a special test. To reconsider how to run the PC for the hour of the processor at the maximum level, at the top left corner, check the boxes next to the words "Stress CPU" and "Stress FPU".

Bazhano does not come out of the machine at the hour of the check and respectfully follow the tribute, like a program. Oskіlki robiti diagnostics of the computer - do half of it, the crime of revealing problems, it is also necessary to allow them to bring the PC out of whack. When critical temperatures are exceeded, next step is to improve the test and think about replacing the cooling system. Let's not start blowing the radiators out of the saw, and then we'll check the temperature again at the maximum interest.

Zboї pіd h igor

As if pardons in the robotic computer are blamed on the process of Igor or other programs that actively fix the graphic system, the diagnostics of the robotic computer can be blamed on the help of the FurMark program.

After the launch, it is clear that it will be fixed. For the new one, select the maximum razdіlnu zdatnіst, which is supported by the monitor, and also put a tick in the "FullScreen" checkbox. Now you have to click on "Stress Test".

A trivial image will appear on the screen, but the next thing to watch out for is not for him. The main respect can be attached to the schedule, which seems to be from below. The new one shows the temperature of the video processor. When critical values ​​are reached, press the "ESC" button to complete the benchmark.

Image Defects

As soon as an hour of work on the monitor, the wrong colors appear, the problem is most likely to be eliminated by a simple replacement of the cable. Diagnosis and re-checking of components. Try tightening the screw to secure the plug. Even if it didn't help, you can wipe the contacts with alcohol and check the cable's usability on another computer or monitor.

Didn't the front ones succeed? Update or reinstall the video driver. Also, we won’t take the test of the graphic card and pay for overheating, as described above.

No sound

How to perform diagnostics of a computer and to detect an incompatibility, how to make a sound? Such problems are blamed after the installation of a new video card or graphics adapter. A lot of similar modern add-ons are supplied with an HDMI output, through which sound can be output. And at the same time, there is a risk of incorrect auto-tuning due to the increased sound of the extensions.

Launch any player and add new music to it. Click on the end of the speaker in the system tray, and then click on the text "Attachments for creation". At the left column of the window, which has appeared, right-click on the mouse on the skin attachment, and indicate the OS, which you need to victorize for locking.

Even though the sound did not appear, computer diagnostics in home minds is more important than additional ones. Flip the darts, yak z'dnuyat that vyhіd audio payment. The easiest way is to turn on the plug to the socket of the computer and connect it to another audio player, mobile phone).

If there is still no sound from the speakers, try replacing the cable. Should the audio system be switched off after the procedure? It means that the computer is more correct, and the replacement means "acoustics".

HDD problems

How to carry out diagnostics of the computer, if the hard disk is not displayed in the explorer, nor in the BIOS? Almost the next line from the re-verification of cables. The simplest is to switch the cable to the HDD, which works stably. As such, such an attack did not help, the high level of damage to the accumulator itself is high. At this point in the distance, try to repair in the home minds not to lead to positive results. Revision of data from this HDD can only be viconated.

If the information from the hard drive can be read, but the OS is captured, downloaded to a new one, not exited, then the MBR (Advantage Record) has been disabled. To solve this problem, start from the Windows installation disk. Next to the menu, press "Introduce computer", and then - "Introduce zavantazhuvach".
