What should I do if the motherboard does not start?

Many of us have experienced computer problems. And it's good if these are problems that you can solve on your own. Worse, if you eventually have to carry the car to a service center. And even if everything is fixed there, it's not a fact that the system will not fail again and will not fail at the most inopportune moment.

If you discard all the talk about complex system errors or some mechanical problems, the rest is generally solvable. On the Internet, a huge amount of videos on the repair of gadgets and computer components. So you can see how to change the screen on your smartphone, how to clean and lubricate the cooler, how to replace thermal paste. And what if the motherboard does not start?

Errors

First you need to understand what could be the cause of the problem. In general, the motherboard is a complex device on which a huge number of elements are placed: from large components to small bolts, sensors and indicators. Due to the fact that the board contains controllers, connectors, slots, chipset, stabilizers, capacitors, etc., it is difficult to avoid errors.

By the way, the presence of all these elements can complicate repairs, affect the methods for eliminating failures. As a result, it becomes clear that errors in this case can be divided into mechanical and system. The first can be fixed with a soldering iron even at home, although the case is quite rare. If the outcome is unsuccessful, physical damage can be eliminated only by purchasing a new device. Sometimes capacitors, power sensors or similar elements that carry voltages can simply burn out because of the load on the system.

System errors are more "flexible". They are easier to fix on their own, although sometimes you have to resort to the help of specialists. But in general, a system error is not a sentence to the device, and if you do not have a motherboard for this reason, do not despair.

Who is guilty?

It is interesting that in general, if there were any breakdowns, it is either user's fault or poor-quality food. In the first case, the buyer could carelessly handle the installation of the board, inaccurately unpack it or use it improperly. In the second case, it can damage the power supply, which not only overloads the board, but also "burns" all the other components on it.

Also to the guilty can be counted those who forwarded the product to you by mail and during transportation damaged something. There are also unscrupulous manufacturers who sometimes make substandard assembly, and also use poor-quality materials, obsolete capacitors, weak radiators, forget about chip cooling, etc.

Home solution to the problem

So, if you have a problem, and you are more or less versed in the technology of the PC system, you can try to fix everything yourself. Please note that intervening in the physical condition of the motherboard removes it from the warranty period, and everything that will happen - all at your own peril and risk.

It is necessary to understand that the printed circuit board consists of several layers, and this despite the fact that the thickness of the plate itself is only a couple of millimeters. Each layer got copper conductors, and if the problem with them, then most likely, you will help the service center or the acquisition of a new platform.

Previously, in older models, the condenser often swelled. This problem could easily be eliminated with a soldering iron. If you have already used this tool, you know how it works, then you can try to solder the small parts, while watching the temperature, and using a thin sting.

Device

Before rushing to eliminate breakdowns or to understand why the motherboard does not start, it is necessary to diagnose an "ailment". Usually, the so-called multimeter or multiverster is used in the service centers. This tool was named because of its versatility: it can check several indicators.

These devices are large. They need to be able to use, understand what is the difference between the analog and digital tester, which will test the stability of the platform. The digital device is the most comfortable to use, it is easy to work with, and it does not require special skills, especially if you have a high-quality model on your hands.

As a result, the multitesters can point to the indicators of voltage, resistance, measures the current strength, checks the resistors, transistors, diodes, the capacity of the batteries and capacitors.

Replacement

Of course, almost none of the ordinary users of the house in the box does not roll an extra multiverster. Therefore, it is necessary to diagnose the breakdown by all possible methods. If your motherboard turns on but does not start, you'll have to change it.

The main advantage of the PC is that there are many components in the case that can be replaced. To find the faulty module, you have to turn off each component in turn. It is worth remembering that much depends on trains, cables, contacts, connectors and other things. This all often leads to disruption of the connecting parts.

Usually, checking this way the work and highlighting the faulty component, experts recommend leaving the motherboard with the chip, power supply and speaker to monitor the audio signals. If this all works, then, most likely, it's in one of the disabled components. Next, it is necessary to connect one each device and monitor its operability. Some do the opposite, taking out each device in turn.

If at this diagnosis you find that the board is starting up, but, for example, the video card does not respond, it does not mean that the graphics accelerator failed. There are problems with cables, with connections and contacts on the same motherboard. Therefore, here you 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 working, or the platform does not show any signs of life, they are completely different. It is interesting that even the system itself can simply be "cunning." For example, if there is a BIOS battery on the board, or if it simply does not exist, the system "pretends to be dead". For this case, the multitestaster just fine, and if you do not have it, carry the product for repair.

There is also a problem with the provision of the standby voltage. To understand whether all is correct from this side, you need to connect the power supply to the board and plug in the power cable. If you do not have a very old model of the platform, the LED on it will light up. If the bulb does not light up, most likely, it is necessary to go again to repair.

A common problem

It happens that the motherboard does not start, but the fans spin. The problem is not the most common and is often seen on older motherboard models. Owners of such devices need to know that problems of this type are often due to the user's negligence. In this case, the usual cleaning will help. Generally, such prevention should be carried out at least once every six months: check the condition of the system, clean the motherboard of dust, monitor cooling and thermal paste. If you abandoned the board, you should not be surprised that a large accumulation of dust led to a disruption in contacts.

In this case, the most successful option is to test the performance of each connector. It is possible that the place where the power unit is connected is heavily soiled and requires regular cleaning. It also happens that the problems in the connectors are noticeable during the external inspection, then it is much easier to understand what needs to be done next: simply change the cable or change the connector.

Capacitors

It is interesting that if the Asus motherboard does not start, then they try to blame it on capacitors. In general, the manufacturer is considered to be conscientious and always equips its models with quality materials. But in the old models there are flaws. Some users decide to solder these parts by themselves, but they do it poorly, which again causes system errors. It happens that the capacitors are changed in the service center, and the motherboard ceases to "live" after a while.

No answer

It also happens that the motherboard starts and immediately turns off. Usually people start to think that the computer has overcome a terrible virus. He "ate" everything that was, and there is no road back. This is a rather rare explanation. Immediately it is worth checking whether the power button is turned on, then you need to look at the system unit and clean it from dust.

Yes, again you have to disconnect everything in turn or disconnect all at once and leave the main elements. It happens that the PC does not turn on due to the power supply, which does not perform its basic functions, although in this case the motherboard would not be included at all. It also happens that the cause of the problem will be indicated by the BIOS, which will emit a certain sound signal.

Where is the image?

Some users are faced with the fact that the motherboard starts, but there is no image on the monitor. Of course, the first and main reason is the failure of the display. But this happens quite rarely, much more often users simply forget to plug the monitor into a power outlet. Also, you need to exclude cable damage and activate the power button on the monitor.

The next reason for this error is BIOS. It sometimes resets the settings and can generally affect the performance of the motherboard. Usually everything is solved if you get into the BIOS settings. But the monitor is silent, so open the PC case and look for the battery. It is responsible for the non-volatile memory and stores the BIOS settings. We pull it out, wait a couple of seconds and insert it back.

As mentioned earlier, there may be problems with the rest of the components. Remember that even dust can be your worst enemy, so if something happened to the PC, immediately open the case and look through each element. Malfunctions can be visible, for example, you can get the motherboard and inspect it for the appearance of dark spots, charred elements or a sharp smell.

Transistors

If you do not start the motherboard Asus or another company, then the reason can be covered in transistors. This is another element that can be checked on its own. We are looking for a short circuit on them. Let and happens such it is seldom enough, but, as they say, it is warned - means it is armed.

For diagnostics, release the board from all power connectors again to avoid accidentally electric shock. We take the multitesters (yes, unfortunately, those who do not have this device can not make this diagnosis) and check all the conclusions of the transistors. This element on the board is difficult to find, since it is small, and there are a lot of details on the platform. A transistor is similar to a square or a rectangle with three leads.

Further the multimeter should work in a mode of "dithering" of diodes. Two elements of the devices need to touch the "legs" of the transistor. Sounds indicate a malfunction of the transistor.

Details

All the above reasons are not the only ones. In general, there are a lot of mistakes that lead to the fact that the motherboard does not start. The first thing to remember is the care of the system. You can not buy a PC and forget about it, it's important to take care of it, clean it, monitor heating, etc.

Among other breakdowns that can disable the motherboard, can call the incorrect operation of the network adapter - a cable that connects the Internet to the system. Due to unstable routers, Internet centers and other devices, there may be voltage surges that lead to the burnout of the circuit.

Often, users face problems in the work of BIOS. Because of them , the Gigabyte motherboard may not start . Typically, manufacturers are trying to present a newer model of this multiprogram platform. But if suddenly an ordinary battery on the board has sat down, then no system implementation will help. You just need to replace it.

Nutrition also plays a key role. If you are assembling the PC yourself, you need to calculate the necessary power, which the power supply unit will handle. In addition, one should not forget about good cooling, as manufacturers, saving on materials, forget to install a couple of extra radiators for power elements or use weak stabilizers.

Another reason why your Asrock motherboard does not start is the damaged ports. Not everyone knows, but turning off the periphery while the PC is working can adversely affect the elements of the board. For example, if you sharply stick your mouse out of the connector, a voltage jump will occur that will cause the port to burn. And it's good, if the unplugged is only a connector ... And if the whole motherboard burns down? I'll have to raise money for a new one.

conclusions

So, remember: if your motherboard does not start, most likely, you will have to carry it for repair. This is the most logical option, which will make your life easier, although it will require additional funds. If you are more or less versed in the work of the PC, you can try to fix everything yourself - after all, sometimes, as we found out, the problem may be hidden in a dead battery or a disconnected cable.

Therefore, we check that all elements are firmly connected, and the power supply unit is turned on. Then we look, whether all voltage regulators and jumpers of the processor are in the correct position: it is necessary that all components are firmly "seated" in their places. If nothing happens, we look closer to the board and look for visible damage, we connect only the necessary elements for initial work. If everything works, then the reason lies in one of the disabled components ,. If the problem is not resolved, then it's better to contact the specialists after all.
