Motherboard Failure Symptoms

Motherboard error is one of the most difficult problems for any user or technician to solve, simply because there are a number of variables to consider. To get to the bottom of a problem, technology usually has to address different software and hardware causes. In general, there are not many signs that can help you diagnose motherboard errors. Whether the motherboard works or not, there’s nothing in between. Other devices, such as fans and hard drives, may continue to work even if the motherboard is dead, but your computer may not work at all.  If you think the motherboard is responsible, consider the following points.

Physically damaged parts. The first thing you want to do, especially if you haven’t opened your computer yet, is physically check your motherboard. This allows you to check whether the capacitor causing the problem is inflated or damaged, as shown in the figure below.

Leaking or inflated capacitors are usually the result of overheating, material defects or simply aging. If you see a capacitor about to explode, you can suspect the cause of the motherboard problem.

Beware of an unusual smell of burning. Another sign of trouble with the motherboard is the smell of fire. In most cases, a very strong burnt smell is a sign that the component is overheated. Sometimes connecting an incompatible component can cause overheating or failure. So if you installed a component before you noticed the problem, make sure to remove it immediately. You can’t just install the component on a motherboard, so check its compatibility first. Connecting incompatible RAM or graphics cards, for example, can cause serious problems and permanent damage to your motherboard.

Random block or freeze. If you have noticed that your computer has recently hung up, the first thing you need to do to solve the problem is to check if the software is faulty. However, if you have already eliminated all software factors, you will need to consider other hardware variables, such as the possibility of the motherboard failing.

Blue Screen of Death. If you have a blue death screen on your computer, it does not automatically mean that there is a problem with your motherboard. In many cases, a bad driver or a hardware malfunction can be the main cause. If possible, pay attention to the error message, especially the error code that looks like this (0x00000000(0x000000,0x000000,0x000000,0x000000,0x00000000). Once you have the code, do a Google search to see if there is a motherboard crash.

Other symptoms may also occur, such as those listed below, although they may be caused by a completely different malfunction. Below you will find other warning signs that you should pay attention to:

  • Some devices seem to stop working for a few seconds.
  • It takes a long time to boot up the computer.
  • The motherboard does not perform a self-test when powering on or booting up.

The reason for motherboard failure.

Now that you have confirmed that your computer’s motherboard has failed, you may be wondering what is causing these problems. Here are some of the most common reasons why a motherboard stops working:

  • Overheating.
  • Fan failure. Dust can accumulate very quickly in the fans, causing them to fail. Make sure you clean the fans in the tower at least once a year.
  • Too much dust in system. Dust, such as heat, can shorten the life of components and the motherboard in general. Try to clean the inside of your computer regularly.
  • Smoke.
  • Accidents in which components are subjected to unnecessary vibration.
  • Ageing.
  • Overvoltages or unstable voltage.

TroubleshootingMotherboard

There are generally two categories of troubleshooting that a user or technician can use to fix a bad motherboard. The first checks whether the computer is running a POST and whether it is booting up, and the second checks whether the system is not running a POST or no longer booting up.

A POST is essentially a diagnostic test performed by the motherboard’s BIOS to determine whether devices such as hard drives, graphics cards, RAM, keyboard or mouse are connected. When the required devices are detected, the BIOS starts up the operating system.

How to know if your motherboard is bad and how to fix it

What should happen if the POST works properly and the computer boots up the operating system?

If your computer is able to boot the operating system after POST, an error in the motherboard is not necessarily the main cause of your problem. You must first exclude other possible hardware reasons to determine whether the motherboard is bad or not.

Check the hard disk. A faulty hard drive can sometimes wrongly be considered a motherboard problem, so you want to make sure it works. If you get a blue screen with a death symptom and it shows an error code, you need to do some research. You should also be careful about the sound it makes, as it is one of the most obvious signs of a problematic hard drive. Sometimes it can take much longer to boot the system if the hard drive is not working properly. In general, the symptoms of a defective hard drive are as follows:

  • An unusual sound
  • Damaged or lost files
  • Accidental freezing or blocking
  • Near-permanent traffic accidents
  • the bad sectors

To solve problems with your hard drive, follow our manual in on this page.

Check the power supply (power unit). Often the most underestimated or even forgotten part, the GPO is just as important as the motherboard itself. However, many users usually don’t pay much attention to it, even if their computer fails. Basically, the AC adapter supplies power to your computer, and if it does not perform its task properly or does not meet the specifications, it may permanently damage the system. If the load on the power supply is too high, insufficient power for the system may cause serious damage to other components. It is therefore necessary to use a good energy source. Please refer to your motherboard’s manual for information on how to check the power supply via the BIOS menu. There are also software utilities from motherboard manufacturers that can do this work.

Central Processing Unit (CPU) Test. Like the core of any computer system, a processor failure often leads to an unstable system or a total system failure. It is therefore relatively easy to detect a problem with the processor, because the whole system works when it is running, does not switch on or becomes unstable when it is not working. If you have an Intel processor, we recommend that you use the Intel Processor Diagnostic Tool to check the status of your processor.

Checking the RAM. Installing non-standard RAM can cause jitter problems, which can sometimes be misinterpreted as a motherboard problem. Unreliable RAM can cause many problems, such as infrequent failures, data corruption, freezing problems, and so on. If the problem occurs after adding the RAM chip, try removing it from the system and restarting it. You can also test the existing memory with free software such as Memtest86 or Memtest86+.

Check the Graphics Processing Unit (GPU). If you see unnatural pixel formation on the screen, or if artifacts appear from time to time, you probably have a video problem. All motherboards have built-in video functions, but these are often not enough for graphics-intensive tasks. To circumvent this limitation, players usually add a more powerful graphics processor to their computer. If you have them installed in your system, the graphics card may be involved. Don’t forget to remove them from your motherboard to see how the system works without them.

Make sure the BIOSfirmware is updated. Sometimes an update of the current BIOS version can correct faults on the motherboard. Please refer to your motherboard’s documentation for information on updating your BIOS.

Perform a visual inspection of the equipment. If you are using a more complex installation with more hardware devices, check all connections. Sometimes restarting connections can work miracles. So just go through each connected device before trying to restart it. Make sure all fans are in operation to ensure sufficient cooling and ventilation.

What to do if the POST does not work and the computer does not start at all.

This second category assumes that nothing happens when the switch is pressed. In most cases, the reason is probably the hardware, so there are important things to check.

Physical test of the motherboard. As said before, you want to make sure that everything is properly connected and that no capacitors leak. Depending on the type of motherboard, an indicator light can help determine whether a critical component such as RAM, hard disk or processor is working. If everything seems normal and there is no visible damage to any of the components, then the motherboard is probably in good condition and there is another reason why the computer doesn’t work at all.

Check the power supply (power unit). Often the most underestimated or even forgotten part, the GPO is just as important as the motherboard itself. However, many users usually don’t pay much attention to it, even if their computer fails. Basically, the AC adapter supplies power to your computer, and if it does not perform its task properly or does not meet the specifications, it may permanently damage the system. If the load on the power supply is too high, insufficient power for the system may cause serious damage to other components. It is therefore necessary to use a good energy source. Please refer to your motherboard’s manual for information on how to check the power supply via the BIOS menu. There are also software utilities from motherboard manufacturers that can do this work.

If you have another working power supply, try using it on your system to see if the current power supply is just dead or faulty. Sometimes too many installed devices can overload your system. Therefore, try disconnecting small parts such as an optical drive or a graphics card to see if your computer is working properly.

Metal oxide control orCMOS in additional semiconductors. CMOS is a built-in chip that stores information, usually BIOS settings, required by the computer, such as date and time, system boot order, etc. CMOS is a chip that stores information, usually BIOS settings, required by the computer, such as date and time, system boot order, etc. CMOS is a chip embedded in the computer’s memory. The CMOS is powered by a battery that can discharge after a certain period of time. This lithium-ion battery helps the CMOS store the variable information used by the BIOS when the computer starts up. When this battery is charged, the BIOS settings are reset to default values after the computer restarts. If you notice that your computer’s clock has changed without your knowledge, this may be a sign that the CMOS battery is low. Don’t forget to consult your motherboard’s documentation if you want to check your CMOS.

Consultation with a specialist. If you have already taken care of everything and it turns out that a motherboard failure is the main reason for one of the above mentioned reasons, we suggest that you have the work done by a professional. Try to avoid repairing your motherboard, especially if you don’t have a strong knowledge of electronics. You may be able to identify a working capacitor, but you need a certain amount of knowledge and experience and the right tools to repair or replace it.

You can of course just replace the motherboard, but you should also consider replacing the same card. Otherwise, other components such as the old processor, RAM or even the power supply may become incompatible with the new motherboard. It’s the same here: If you’re not sure, try consulting a professional if you’re not sure what you’re doing.
