What to do if the motherboard does not start? The motherboard does not start from the "Start" button. How to repair a computer with a frequently faulty motherboard? Why won't the motherboard start?

Methodology for repairing motherboards

The motherboard starts, but after an hour it freezes.
Sometimes, after a blackout, your life cycle can “nervously” slow down, and the computer does not start up, and to restart it is necessary to turn it off and turn it on again.
The reason for such a shutdown, as a rule, is the capacitors that have dried out, it is necessary to replace everything with great care.
Dying APM transistors - change.

The motherboard starts “every other time”;
The reason for this may be that the capacitors are swollen (visual inspection) - change.

Validation of the original bridge (chipset) - you can check the pressure on the skin from the newcomers and avoid the price of switching it on - you need to work on warming up and rebowling the conductor chip . Just like that, after turning on the payment for a long time, it freezes after an hour - it’s “on the way”
It may be that there is a problem in the BIOS of the motherboard for flashing.

It starts, but after an hour it freezes (everything freezes, including images);
The main bridge (chipset) needs to be warmed up and rebowled. So the motherboard itself can turn on every other time.
The capacitors may be blown, most often in the life of the processor - change them.

It starts and displays BIOS Checksum Error or similar notifications;
The BIOS is corrupted, and the block will “boot”, which requires sewing.

The motherboard gets stuck, and then after a second (maybe less) gets stuck.
Whenever you go to protect the life block, you need to check for a short circuit in the power inputs of the motherboard, most often the 12v line of the processor, or broken transistors.

Mimovoli will be re-invited.
The operation of the dual-channel memory mode is incorrect - adjust the timings, or set the single-channel mode.
Unstable food - check the capacitors.
There may be a problem in the motherboard BIOS.

It freezes, but doesn’t start (nothing on the monitor);
In this case, you need a post card, as well as a payment code. If the post card does not show anything or just zeros, it means that the life of the processor or chipset is damaged. If the chipset or processor socket fails, you will need to be aware that the reset code changes when pressed on the external microcircuits, and possibly during startup - warming up or rebowling. Well, for the song of mercy it is important to focus on it.

The motherboard does not start (does not respond to the power button);
In this case, it is necessary to check all the lanyards of the drawing life, all the lanyards for shortness to the ground, for different models of payment - in different ways, the voltage on the life button, etc.

Motherboard "do not leak" PCI devices

If the motherboard does not recognize the connection devices to the PCI connectors (margins, sound boards, etc.) and the PCI controller bus has burned out, you need to change the original location.

Because the motherboard does not support SATA/IDE devices

There may be little risk of damage to the system BIOS, but rather less damage to the physical controller (CM). Possible also the YUM branch - necessary rebowling or as a minimum of warming up.

Doesn't use USB

Damage or damage to the life of the USB ports

The first suspicion fell on the life block. Replacing it with a clearly referenced power supply unit did not give a positive result. Subsequent replacement of important components of the system board (memory, processor, video card), as well as connecting the hard drive and DVD did not change the situation.

We wanted to try turning on the life block by applying the “General” potential to the PS-ON wire. The short-term torkanya was enough, and the motherboard started. After installing all components, the operating system was successfully installed.

The next step is that the scheme for launching the life block came out well. It is practically impossible to repair the motherboard without drawing a schematic diagram and describing how everything works. On the other hand, replace the motherboard, and possibly other components installed on it are happy to last on the road.

To solve the problem with switching on, in such situations, you can overmix the PC power button as shown in the pictures.

You can not scratch the button, but install an additional one. Whose failure has a great advantage. If the situation is that the computer is stupidly frozen, not responding to anything, pressed and pressed for 4 seconds. The main buttons can be easily pressed. You can’t use the additional button to do this, you can just snatch it away. Additional button can be used without fixation!

If your computer does not turn on and sees a series of incomprehensible beeps, you can assume that your motherboard is not working properly. This problem is even serious, since the fragments of the motherboard are a systemic element.

It itself contains vitally important components such as a processor, video card, sound card, etc.

Problems of this kind need to be resolved as quickly as possible, even if the device’s components can damage the CPU, video adapter, and other parts, making repairs much more expensive. What should we do if the motherboard doesn’t work and why can we encounter such inconveniences?

If your motherboard is not working properly, that’s the main reason why the capacitors are leaking.

These electronic elements require the accumulation of electrical energy through their planned supply to the main component boards: processor, video card, intermediate card, etc. If the voltage exceeds the permissible maximum, the stench may swell and leak, causing the motherboard to fail.

If you noted that the motherboard does not work through it, do not rush to throw it out and buy a new one. This problem arises from the additional re-soldering of these electronic elements. I really appreciate that you shouldn’t try to do this operation on your own! This can lead to the following problems:

• Output of other radio components or components of the motherboard;
• maintenance of paths;
• Fluxed.

For such work, a soldering iron with a thin tip and a power of 40 W is used. It is not recommended to overestimate this value, since the motherboard is even a sensitive element of the PC. In this manner, you can get into much more serious harm.

If your motherboard does not pass through capacitors that are swollen, such repairs will be effective. The motherboard lends itself well, and after replacing these radio elements, you can run it for about three hours.

For example, from the practice of the “Expert” service center, there is a problem when one of the motherboards after this procedure was able to perform two or more problems. Just after the end of the appointed hour, the problems began again. It should soon be noted that such inconveniences are likely to become chronic. Since one motherboard can handle two problems, other problems can arise within a month, unfortunately, there’s no telling here.

Why is it important to be careful when soldering capacitors on the motherboard?

By re-soldering the capacitors, it is important to ensure that their polarity is respected. This always cannot be confused, since such a misunderstanding can lead to a whole series of negative phenomena:

• The radio output is in good condition;
• Boiling electrolyte;
• Possible vibration of the capacitor.

It is difficult to determine the polarity on a radio element. “Plus” is not indicated on anything, but “minus” is indicated by a great white dark. On the mother’s side, the polarity is designated as primary for the skin: “+” and “-”.

Therefore, when soldering, it is necessary to pay attention to all the marks that are on the device and radio components.

It is important to remember that the skin capacitor has the same characteristics as a new radio element.

Thus, since the part carries a nominal voltage of 10 V, and its capacitance is 3300 mF, then similar indicators will appear on the new capacitor, which will be installed in place of the old one. Since there is no such device, you can try to quickly use an analogue with slightly shorter characteristics, but always not with worse ones. This is very important.

Diagnosis of board problems

Since a visual inspection did not show frequent malfunctions with capacitors, as well as numerous traces of burning of radio components, it is necessary to carry out a thorough diagnosis.

As a minimum, for which you need a multimeter, which is an unknown attribute of any PC repair service center or anything else. We really appreciate that with this tool it is necessary to take advantage of it.

Without the necessary skills, know about electronics, even if you try to independently identify a malfunction.

The multimeter is necessary for monitoring a number of indicators of most elements of the motherboard. Zokrema will be red during such operations as:

• Vimir voltage;
• Freeze the support;
• Vimir sili struma;
• increased capacity of the motherboard life element;
• Testing of electronic components of the motherboard, especially heavy-duty capacitors.

I immediately express your respect for those who, in such situations, simply “feign” wrongdoing.

For example, it often causes problems with the BIOS battery.

Without it, the computer will not start, which becomes a cause of panic for many PC owners, although the problem is easy to solve.

I know, a multitester can help here, which allows you to reduce the capacity of the life element. It is very important to remember this, even though not all problems of the soul are terrible.

Well, any search for malfunctions of motherboards always begins with this very thing, and with the verification of the presence of the worm voltage. This is easy to verify: you just need to connect all the sockets from the living block and connect it to the limit. There is a special indicator on the motherboard that shows the voltage level. If the wine burns, you can continue to detect a malfunction, if it is not a very serious problem. Such faults are to blame either from the front office or from the minds of the service center.

Sound of faulty transistors

Another problem that can cause the motherboard to go wrong is a faulty transistor.

The problem is widened when a short circuit in this radio component causes it to go out of tune, and at the same time the entire motherboard becomes damaged.

For this diagnosis, you also need a multitester; without this, this malfunction cannot be identified.

Also, before starting to diagnose this type of computer, you need to connect the motherboard to the power supply. This can be divided in two ways:

• Connection to the living unit as a whole, using a special button;
• Connect all cables that connect the motherboard to the power supply.

Then it is necessary to identify the skin transistor assembly and transistors and “ring” them. For people familiar with the payment system, there are no particular difficulties. Newcomers may have problems.

The ringing of transistors occurs after setting a special mode on the multitester.

The fragments of professional masters have a unique possession, as a rule, among those present there. Then the skin of the transistor's legs is sequentially cleaned until a specific sound signal appears. If the multimeter is no longer running, then a faulty radio component has been detected. It is obviously beyond repair, so it needs to be replaced with a new one.

A special feature of motherboards is the frequent breakdown of transistors in the central processor. The main problem in this case lies in the sequential connection of these life elements, through which the multitester will show a malfunction in every tester. What specific transistor is not working? This means that this is possible in only one way, through the sealing legs of the parts and through the additional ringing of the skin.

Replacing transistors that were confirmed

Working with these radio components involves some particularity and soldering, which ultimately involves a specific circuit. First of all, one leg of the device is soldered and carefully raised above the board.


It is necessary to work very carefully, since the theoretical feasibility of their robots is still active. If you are not careful, there is a risk of damaging your legs and then the transistor will definitely become faulty.

After the legs are soldered, the radio components need to be warmed up.

The turn is a special cradle of the transistor, with which it is soldered directly to the motherboard. At professional service centers, during the hour of working with a soldering iron, a set of specific nozzles is required. It’s easy to simplify the process, as long as you can paint the tip from the radio component.

Therefore, after the old transistor is soldered, it is necessary to install a new one in its place. Work with all the attributes of a soldering tool: solder, flux, etc. It is not excluded that when replacing radio components, you will also have to insert capacitors to make access easier. There is nothing terrible about it, the stench is removed, and it is installed back without serious damage. You will need to install them again as soon as you no longer need the extra space and the soldering of the transistor is completed.

• Troyandi;
• Wooda.

Why? The stench is entirely inferior to its analogues. In advance, it’s better to melt at extremely low temperatures. For Rose, 94 degrees is enough, and for Wood, even less - just 68. At the same time, practically all the radio components of the motherboard are soldered using refractory solder. It may not be easy to pull them off.

This is where the plus of Wood and Rose solders lies. Vikorite granules can significantly reduce the temperature of soldering of radio components, and this is a great plus.

Many of us are stuck with computer problems. And good, because there are problems that can be solved independently. Girsha, I hope I have to take the car to the service center. And if we can correct everything there, it is not a fact that the system will not fail again and will not fail at an unexpected moment.

As soon as we throw out all the concerns about folding system grinders or any mechanical problems, the solution as a whole remains unsolved. There are a large number of videos on the Internet dedicated to the repair of gadgets and computer components. This is how you can do things like change the screen on a smartphone, how to clean and lubricate the cooler, how to replace thermal paste. What should you do if the motherboard doesn’t start?

Pardons

It is first necessary to understand what could be causing the problems. The motherboard is a folding device on which a large number of elements are placed: from large components to small bolts, sensors and indicators. Through those on the board that contain controllers, connectors, slots, chipsets, stabilizers, capacitors, etc., it’s easy to remove problems.

Before speaking, the detection of these elements can complicate repairs and influence methods for eliminating faults. As a result, it becomes clear that grinding can be divided into mechanical and systemic. The first ones can be corrected using a soldering iron at home, if you want to avoid a rare outbreak. If the result is not satisfactory, physical care may be reduced to the purchase of a new device. Some capacitors, life sensors, or similar elements that carry voltage can burn out if they come into contact with the system.

Systemic benefits are more “little bitch”. It’s easy to correct them on your own, even if you need to get help from the fakers. But in general, it’s a system fix - it’s not a solution to the device, and if your motherboard doesn’t start for this reason, don’t fall for it.

Who is to blame?

Anyway, in general, as some breakdowns have occurred, the fault lies in the faulty or unclear food. At first glance, the buyer may carelessly fiddle with the installation of the board, unpack it carelessly or use it incorrectly. In another case, you may damage the life block, which will not only change the board, but also “burn” the components on it.

You can also secure those who transported the product by mail and during the time of transportation it was damaged. There are also unscrupulous generators that waste uncleared materials, waste uncleared materials, old capacitors, weak radiators, forget about cooling the chip, etc.

Home problems

However, if you have experienced some kind of problem, and you have less knowledge of PC system technologies, then you can try to fix everything yourself. Please note that the delivery of the physical motherboard removes it from the warranty term, and everything that happens is at your own risk.

Now, understand what is made up of so many balls, and yet the thickness of the plate itself is just a few millimeters. The skin is equipped with copper conductors, and if there is a problem with them, then the service center will help you with everything or add a new platform.

Previously, with older models, it was often damaged. The problem could easily be fixed with the help of a soldering iron. If you have already worked with this tool, you understand that you can try soldering other parts, at which the stitches vary according to temperature, as well as a thinner tip.

Prilad

First of all, you will rush to fix breakdowns or figure out why the motherboard does not start, you need to diagnose the “illness”. Call your service centers and call them multimeter or multitester. This name of the instrument, however, deprives it of its rich functionality: you can change the number of indicators.

There are a lot of things like this. You need to study them, understand the difference between an analog and digital tester, in order to check the stability of the robot platform. The digital device is the most comfortable for Vikoristan, it’s easy to use, and it doesn’t require any special skills, especially if you have a clear model on your hands.

As a result, the multitester can measure voltage readings, support, vibrating power, check resistors, transistors, diodes, battery capacity and capacitors.

Replacement

Of course, practically no one in the world has a fancy multitester lying around in their drawer. Then you will have to diagnose the breakdown using all possible methods. If your motherboard freezes but does not start, you will need to replace it.

The main advantage of a PC is that there are no components in the case that can be replaced. To identify the faulty module, you need to turn off the skin component. It’s important to remember that there is a lot of stuff lying around in cables, cables, contacts, connectors, and so on. This often leads to the destruction of spare parts.

Call, checking the robot in this way and seeing a faulty component, the technicians recommend removing the motherboard with a chip, the power supply unit and the speaker in order to monitor the sound signals. Since everything works, then, for everything, on the right in one of the connected components. Next, connect one skin device at a time and follow each step. Deyaki to hesitate, grasping the skin device across.

During this diagnostic, you found that the board starts up, but, for example, the video card does not respond, which does not mean that the graphics processor itself is faulty. There are problems with the cables connected to the contacts on the same system board. Then he will have to check everything, connect the video card to another PC, replace the cable, etc.

Cunning

The reasons why the motherboard does not start, the fans are running, or the platform does not show signs of life are completely different. It’s cool that the system itself can simply be “cunning.” For example, if the BIOS battery on the board is dead, or it’s just a day, the system “pretends to be dead.” For this reason, a multitester is a great solution, and if you don’t have one, take the product in for repair.

This is a problem with the power supply. To understand that everything is OK on this side, it is necessary to connect the power supply unit to the board and connect it to the new power cable. If you have an older model of the platform, the LED on it will light up. If the light bulb didn’t burn out, it’s a shame for everything, I’ll have to call in for repairs again.

The problem has been expanded

It's frustrating that the motherboard won't start, but the fans won't spin. The problem is not widespread and most often noted on older motherboard models. Owners of such devices need to know that problems of this type are often associated with the lack of balance of the operator. In this case, you need some help with cleansing. You should carry out similar preventive measures at least once in a while: check the system, clean the motherboard, keep coolers and thermal paste. If you have paid a fee, then there is no need to wonder that the great buying led to the destruction of contacts.

Which option has the best option - to verify the usefulness of the skin rose. It is possible that the place where the life block is connected is very congested and needs urgent cleaning. It also happens that problems in the connections are noticeable upon closer inspection, so it is much easier to understand what needs to be done next: just change the cable or change the connector.

Capacitors

It's cool that if the Asus motherboard doesn't start, there are problems with the capacitors. Nowadays, the manufacturer is respectful and will always equip its models with acidic materials. However, older models have some flaws. Some hackers are likely to re-solder these parts on their own, otherwise it is unclear what causes the system to break down again. It happens that the capacitors are replaced at the service center, and the motherboard stops “living” after an hour.

There are no sub-videos

It may happen that the motherboard starts up and immediately freezes. People are starting to think that a terrible virus has infected their computer. Everything that has happened is gone, and there is no turning back. This is a rare explanation. Immediately check that the PC power button is not stuck, then you will need to check the system unit and clean the saw.

So, again you will have to turn everything on one by one, or turn everything on at once and lose the main elements. It turns out that the PC does not turn on through the life block, which does not preserve its main functions, although in this case the motherboard would not turn on. It is also possible that the cause of the problem is the BIOS, which is a kind of singing sound signal.

Where is the image?

Some computers have shut up because the motherboard starts, but there is no image on the monitor. Of course, the first and foremost reason is a breakdown of the display. However, it is rarely possible to get enough power; more often than not, computer users simply forget to connect the monitor to the outlet. You also need to turn off the cable connection and activate the power button on the monitor.

The reason for this loss is coming - BIOS. At this point, the training is lost and the spirit can be affected by the work of the soul. Make sure everything turns out that you need to wait until the BIOS is adjusted. Before you wash the monitor, open the PC case and find the battery. It protects the energy consumption of the memory and saves the BIOS settings. We pull it out, check it for a few seconds and insert it back.

As mentioned earlier, there may be problems with other components. Remember that this may turn out to be your greatest enemy, as it happens with your PC, immediately open the case and look at the skin. Problems may be visible, for example, you can remove the motherboard and look around until dark spots, burnt elements or a strong smell appear.

Transistori

If your motherboard from Asus or other companies does not start, then the reason may be in the transistors. Here is one more element that you can independently verify. We chatter briefly at them. Let it go and it’s rare to finish it, otherwise, as it seems, advances mean spoiling.

For diagnostics, we re-connect the board to all power outlets, so that you don’t inadvertently hit the strum. We take a multitester (so, unfortunately, those who do not have this equipment cannot perform this diagnostic) and check all the transistor connections. It is important to know this element on the platform, there are many fragments, and there are a lot of parts on the platform. The transistor is similar to a square or rectangular with three visors.

Details

All guessed reasons are the same. In the end, there are no excuses that lead to the fact that the motherboard does not start. First of all, what do you need to remember - this is a turbo about the system. You can’t buy a PC and forget about it, carefully look after it, clean it, keep it warm, etc.

Among other failures that can cause the motherboard to go wrong is the incorrect operation of the adapter - the cable that connects the Internet to the system. Unstable routers, Internet centers and other devices can cause voltage surges that lead to high voltage.

Business owners often struggle with BIOS problems. The manufacturers are trying to present a new model of this multi-program platform. If the primary battery on the board is weak, then any system troubleshooting will not help. You just need to replace it.

Food also plays a key role. When assembling a PC yourself, it is necessary to remove the required tension, which is where the life block fits. In addition, it is necessary not to forget about good cooling, since manufacturers, relying on materials, forget to install a couple of strong radiators on the power elements or use weak stabilizers.

Another reason why yours won’t start is because of damage. You don’t know everything, but if the peripherals are damaged during PC operation, it can negatively affect the payment elements. For example, if you sharply hang a bear from a socket, there will be a voltage surge that causes the port to burn. And it’s good, because the non-working ones will show up without the roses... And what if the system board burns out? You will have to collect money for a new one.

Visnovki

So, remember: if your motherboard does not start, you will probably have to take it in for repairs. This is the most logical option that will make your life easier, even if you get extra cash. If you know more about PC work, you can try to fix everything yourself - even if we found out, the problem may be in the battery, which is discharged, or in the connected cable.

Therefore, we check that all elements are properly connected, and the life block is turned on. It is also surprising that all the voltage regulators and jumpers of the processor are in the correct position: it is necessary that all components “sit” properly in their places. Since nothing appears, we take a closer look at the board and see visible damage, including the necessary elements for the cob operation. If everything works, then the reason lies in one of the connected components. If the wrong is not corrected, then it would be better to turn to fakivts.

Get started checking the usefulness of the motherboard You will need a working life unit and a working processor before preparations. Since the computer processor rarely goes out of tune, you can get by with a life block, or even 100% robotics. Take a moment to check the usefulness of the mother's payment and live with friends or relatives. Without it, it will be impossible to carry out a diagnosis.

1) For the cob checking the usefulness of the motherboard You need to connect the working life unit and first carry out a visual inspection of the motherboard. Slide check the evidence control light diode on the motherboard.

The absence of indication of the control LED on the motherboard indicates the presence of life (the reason is a non-functional part of the motherboard). Now, what needs to be verified - this capacitors on the motherboard. As a matter of fact, their replacement will not lead to stable operation of the system in the near future. Yakshcho you showed Blown capacitors on the motherboard, then replace them as soon as possible with capacitors.

2) At the next stage, take a closer look at the problem associated with. A common reason for motherboard failure is the BIOS.

If the reason for the failure of the motherboard became after its firmware, or when flashing the BIOS, life was switched on, and if resetting the BIOS does not help, then you have a direct route to the service center.

3) If all previous manipulations on your motherboard were not successful, then you need to first turn on your life unit and transfer all devices to the system unit, leaving life on the motherboard unplugged board, processor cooling system and do not forget to connect the internal speaker for due to a malfunction of the system unit

Connect the living unit to the limit, the internal speaker is responsible for producing sound, the sound of memory failure ().

If at this stage you hear a sound signal of a malfunction (non-interruptible signal), then you are more confident that your motherboard is OK. Since the internal speaker does not produce the required sound signals, you will not be able to replace the motherboard.

4) If at the next stage you heard a sound signal of a malfunction of the RAM, then install a valid RAM in the slot and turn off the computer. At this stage you will hear a sound signal indicating a video card malfunction. As a rule, the sound signal of a video card failure consists of four sound signals - one long, three short. If you hear this sound signal, then your motherboard is working fine, and the cause of the problem can be traced to the computer’s video card.

5) At this stage, we check the usefulness of the video card. If at the next stage you heard the beep sound of the video card, insert the video card into the slot on the motherboard, remembering to connect the video card (as there is an additional video card connector). Connect the monitor to the system unit and turn on the computer. As soon as you hear a short single sound from the new speaker, which informs you that the system unit’s devices are OK and you enter the BIOS splash screen, your motherboard is OK.

As if nothing happened, your video card is faulty and needs to be replaced.

If the previous steps 1-4 were completed successfully, then the cause of the malfunction is the video card, hard drive, or other device.
