The motherboard is the basis on whichbuilt system. Of course, without a CPU and a power supply, it will not work at all, but it is still considered the “blood system” of the PC. As with any other component, there can also be some problems with the board. And many are very upset when the platform fails, because buying a new one can lead to hardware incompatibility of components.
If problems occur, you should immediately thinkon how to check the motherboard. You may be able to fix any defects yourself. In addition, many problems can be noticeable even to inexperienced users.
What is needed for diagnosis?
Some people want to know if you can check a motherboard without a processor. Immediately answer that without this component is allowed to diagnose. But without a power supply will not work.
CPU, GPU and BP - the components that are most oftenfail. It is because of them that many begin to check the performance of the board. This especially applies to the power supply, which is important to learn how to choose correctly in order for the system to work stably.
Before checking
How to check the motherboard onperformance? The first thing you need to carefully examine it. But before that connect the power supply to it. If you have one of the latest models, then on it you will find a toggle switch, which in the assembled state of the PC is located on the back panel of the system unit.
If the board is old-fashioned, you will need to "pochaman" to connect it. We'll have to close several contacts. To do this, you need to find out the model of the board and find ways to connect it without a button.
If the component is working, a light will come on. A red or green LED is located on one of the edges of the device. Therefore, you will need to inspect the platform carefully.
Visual inspection
How to check the motherboard?If the indicator does not light up, and you understand that there are some problems with the board, you will need to identify them. To do this, you will have to carefully examine and, possibly, even smell the charge (to identify the burnt areas). What should I look for?
- scratches on the component;
- condition of capacitors;
- extra details;
- deformed elements and connectors;
- pollution;
- BIOS battery.
External damage
How to check the motherboard - knows noteach, but it is easy to guess that the first thing you need to examine it. If you notice any scratches or cracks, it means that the performance of the device is already under threat. Even the smallest scratches can harm the board and the system. This is due to the fact that the contact lines intertwine with each other and pass through the entire textolite. If at least one millimeter of this space is broken, then failures will be observed.
Capacitors
Batteries are most often subject to differentmalfunctions. Condens swelling is a common problem that can occur with both the motherboard and the power supply. Both in one and in the other case, the problem indicates that something really happened to the board.
Condensers look like cylindrical turrets.They are easy to see, although they have decreased significantly over the past few years. How to understand that they are swollen? Well, firstly, capacitors do not swell all at once, so you will notice a difference in their appearance and you can compare. When bloated, the element loses its cylindrical shape and some deformation is noticeable. Also the outer covering of the part is broken.
Что делать, если такая проблема обнаружилась?You can include a fee to the service center, where you will change the capacitors for workers. There is also an option to do it yourself. To do this, it will be necessary to purchase new parts on the radio market and replace the damaged ones.
It is important to understand that over time it may be necessary to once again figure out how to check the motherboard for operability, since such a procedure does not give any guarantee.
Unnecessary parts and deformation
If something happens to the capacitors,it means that other details may come into disrepair. Need to inspect the board for the presence or absence of any details. If something is missing, you will notice it almost immediately. Perhaps you will find on the board a chipped piece of one of the parts of the device. In this case, it will become clear that some element works incompletely.
You also need to inspect the device for the presence ofdeformations. For example, one of the contacts may be unnaturally arched in the other direction and you will notice a trace along which it should be located. It may be that the contacts of one of the slots are broken or deformed. All this accurately affects the performance of the system.
In this case, you can hardly do anything. It is advisable to take such a fee to a service center, where specialists can “make a diagnosis” and determine the future fate of the device.
Cleaning
How to check computer motherboard?In the case of visual inspection, a lot can be said pollution platform. The fact is that few of the users pay much attention to cleaning the computer. Because of this, many errors and failures occur.
It is necessary to monitor not only the purity of the system.cooling and power supply, but also behind the motherboard. Some small hairs and dust can interfere with the work of some contacts. And if there are noticeable pieces of dirt on the board, it means you need to seriously pursue it.
Immediately it should be noted that you can not usesynthetic due to its static properties. It is recommended to use compressed air (no more than 3.4 atmospheres). This is the most secure option that does not force the user to touch contacts and other connections with their fingers.
For thorough cleaning, use a soft brush. She needs to work in the places where dust accumulates the most: power supplies, fans, air intakes and radiators.
Reset
How to check if the motherboard is working?Sometimes not enough of the above procedures. It may be that the performance is suspended due to system failure. Users note that often the board began to work actively after resetting the settings. What do I need to do?
On the motherboard there is a BIOS battery. It is very similar to that used in wristwatches, only of large sizes. The battery is responsible for all computer settings.
First you can try to get it.Do not try to pick it with improvised means. Near the connector there is a lever that easily pulls out the battery. Wait 5-10 minutes and reinstall it in the slot. After resetting the system, the system can earn again.
Why did the system crash?Some inexperienced users and overclocking newbies can harm the system with their experiments. To avoid critical situations, the BIOS protects the system and blocks its operation. After reset, everything will return to the original parameters.
If the fee refuses to respond to anyCommands, try replacing the battery. If a low-quality battery was installed on the motherboard, it could lose all its charge in a year. Due to the fact that the battery is discharged, the board does not turn on. Find the label on the battery and get the same new one.
Conclusion
How to check the motherboard, few know.If you do not have enough knowledge, it is better not to experiment on your own. In the service center, the specialists themselves diagnose the breakdown and advise what to do next. If you still have enough knowledge and experience, you can carry out the above procedures, but not the fact that the failure can be visually diagnosed or corrected by resetting the settings. You may need a speaker who will indicate the problem by sound.
