Before we get to the main topic, let us remind you that we accept requests for help with your Windows computers. If you have a problem for which you do not seem to find a solution, please send us your problem by clicking on the link at the bottom of this page. Remember that window problems are sometimes difficult to diagnose. So try to give us a very detailed description of the problem. You want to mention the relevant story that may have led to this problem. The more information you provide, the better chance we have of making the diagnosis. We also expect you to list the steps you took to resolve the issue before contacting us to prevent the issue from repeating in our article. Again: The more details you give us, the faster we can determine the exact cause and the appropriate solution.

Mainboard error symptoms

Motherboard defects are one of the most difficult problems a user or technician can face, simply because there are a number of variables to consider. To get to the bottom of the problem, the technician usually has to track down several software and hardware causes. There are usually not many signs to diagnose a faulty motherboard. The motherboard either works or doesn’t work, 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 stop working altogether.  If you think the motherboard is the culprit, consider the following.

Physically damaged parts. The first thing to do, especially if you haven’t opened the computer yet, is to physically check the motherboard. This allows you to determine if a burned or damaged capacitor is the cause of the problem, as shown in the illustration below.

Leaking or blown capacitors are usually the result of overheating, material defects or simply aging. If you see a capacitor that is about to blow, you can assume that the motherboard is the source of the problem.

Look out for an unusual smell of fire. Another sign of a motherboard problem is a burning smell. In most cases, a very strong smell of burning is a sign that the component has overheated. Sometimes connecting an incompatible part can lead to overheating or malfunctioning. So if you installed a component before you noticed the problem, you should remove it immediately. You can’t just install any component on any motherboard, so check compatibility first. Connecting an incompatible memory or graphics card may cause a problem. B. cause serious problems and permanently damage your motherboard.

Inadvertently block or freeze. If you’ve noticed your computer crashing lately, the first thing you should do is check to see if there is any software involved. However, if you have already ruled out all software factors, you must then consider other hardware variables, including the possibility of motherboard failure.

Blue death screen. If a blue screen appears on your computer, it does not automatically mean that there is a problem with the motherboard. In many cases, the underlying cause may be a faulty driver or a hardware error. If possible, note the error message, especially the error code, which looks like this (0x0000(0x0000,0x0000,0x0000,0x0000,0x0000,0x0000). If you have the code, search Google to see if it says anything about the faulty motherboard.

Other symptoms may occur, such as those described below, although they may be caused by an entirely different malfunction. Other warning signs that should be kept in mind are listed below:

  • Some devices don’t seem to work for a few seconds.
  • The computer takes a long time to start up.
  • The motherboard does not perform power or consumption self-diagnostics.

The reason for mainboard failure

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

  • Overheating.
  • Fan failure. Dust can accumulate very quickly in the fans, which can cause them to malfunction. Be sure to clean the fans in the tower at least once a year.
  • Excessive dust in system. Dust, like heat, can shorten the life of components and the motherboard. Try to clean the inside of the computer regularly.
  • Smoking.
  • Unintentional fall where components are unnecessarily struck.
  • Getting older.
  • Overvoltage or unstable voltage.

MotherboardTroubleshooting

There are generally two categories of troubleshooting that a user or technician can use to resolve a faulty motherboard. The first controls whether the computer turns on and starts, and the second controls whether the system turns on or not.

POST is essentially a diagnostic test performed by the motherboard’s BIOS to check if peripherals such as hard drives, video cards, RAM, keyboard or mouse are connected. When the required devices are detected, the BIOS loads the operating system.

What to do if the POST is successful and the computer starts the operating system

If the computer can boot the operating system after POST, a faulty motherboard may not be the cause of your problem. You must first rule out other possible hardware causes to determine whether or not the motherboard is defective.

Check the hard disk. A faulty hard drive can sometimes be misinterpreted as a problem with the motherboard, so make sure it’s working. If you get a blue screen with a death symptom and it displays an error code, be sure to look for it. Also listen for sound coming from the hard drive, as this is one of the clearest signs of a problematic hard drive. Sometimes booting up can take much longer if the hard drive is not working properly. In general, the symptoms of a failed hard drive are as follows:

  • An unusual sound
  • Damaged or lost files
  • Unintentional freezing or blocking
  • Traffic accidents, which are almost permanent…
  • the bad sectors

To troubleshoot the hard disk, follow the instructions in section on this page.

Check the power supply. The power supply, often the most underrated or even forgotten part, is just as important as the motherboard itself. But many users usually don’t pay much attention to it, even when their computer breaks down. Essentially, the power supply provides your computer with power, and if it doesn’t do its job properly or to the specifications, it can cause irreparable damage to your system. If the load on the power supply is too great, the resulting inadequate power supply to the system can cause serious damage to other components. Therefore, it is necessary to use a good power supply. Refer to your motherboard manual to check the power supply voltage through the BIOS menu. There is also utility software from motherboard manufacturers that can perform this task.

Central unit control. Like the core of any computer system, a faulty CPU often leads to system instability or complete system failure. It is therefore relatively easy to detect a problem with the processor, since the entire system either runs when it runs, fails to boot, or becomes unstable when it doesn’t. If you have an Intel processor, we recommend that you use the Intel Processor Diagnostic Tool to check the status of your processor.

RAM test. Installing non-standard RAM can lead to jitter problems, which can sometimes be misinterpreted as a motherboard problem. An unreliable memory can lead to many problems, such as. B. lead to frequent crashes, data corruption, freezing problems, etc. If the problem occurs after you add a RAM chip, you can try removing it from the system and rebooting. You can also test your existing RAM with free software like Memtest86 or Memtest86+.

Checking the Graphics Processing Unit (GPU). If you see unnatural pixels on the screen, or if artifacts appear from time to time, you probably have a video problem. All motherboards have built-in video functionality, but it is often insufficient for graphics-intensive tasks. Gamers usually equip their computers with a more powerful graphics processor to get around this limitation. If it is installed on your system, the graphics card may play a role. Consider removing it from the motherboard to see how the system works without it.

Check whether the BIOSfirmware has been updated. Sometimes an update to the current BIOS can fix defects on a motherboard. Refer to your motherboard’s documentation for information on updating your BIOS.

Make a visual check of the equipment. If you are using a more complex installation with many additional hardware devices, check all connections. Sometimes restarting connections can work wonders. So check each connected device before trying to restart it. Make sure all fans are working to provide adequate cooling and ventilation.

What to do if POST fails and the computer does not boot at all.

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

Physical check of the motherboard. As mentioned earlier, make sure everything is connected properly and that there are no capacitors leaking. Depending on the type of motherboard, the LED can help determine if a critical component such as RAM, hard drive or CPU is working. If everything seems normal and no parts are visibly damaged, there is most likely nothing wrong with the motherboard and there is some other reason why the computer is not working at all.

Check the power supply. The power supply, often the most underrated or even forgotten part, is just as important as the motherboard itself. But many users usually don’t pay much attention to it, even when their computer breaks down. Essentially, the power supply provides your computer with power, and if it doesn’t do its job properly or to the specifications, it can cause irreparable damage to your system. If the load on the power supply is too great, the resulting inadequate power supply to the system can cause serious damage to other components. Therefore, it is necessary to use a good power supply. Refer to your motherboard manual to check the power supply voltage through the BIOS menu. There is also utility software from motherboard manufacturers that can perform this task.

If you have another power supply whose operation is known, try that on your system to see if the current one is just dead or defective. Sometimes too many installed devices can overload the system. Try turning off unnecessary components, such as an optical drive or graphics card, to see if the computer is working properly.

Check for metal oxide orCMOS in another semiconductor. CMOS is an embedded chip that stores information, usually the BIOS settings that the computer needs, such as B. Date and time, system boot order, and others. The CMOS is powered by the battery, which can become discharged after a certain time. This lithium-ion battery helps the CMOS to store the volatile information used by the BIOS when the computer is booted. If this battery is charged, BIOS settings will return to default after the computer is restarted. If you notice that your computer’s clock has changed without your knowledge, it may be a sign that the CMOS battery is low. Remember to consult your motherboard’s documentation when checking the CMOS.

Consult a specialist. If you have already ruled everything out and it turns out that a faulty motherboard is the cause, we recommend that you have the work done by a professional. Try to avoid motherboard repair, especially if you don’t have a good knowledge of electronics. You can detect a leaking capacitor, but you need a certain amount of expertise and experience, as well as 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 your old processor, memory, or even the power supply, may no longer be compatible with your new motherboard. Again, consult a professional if you are not sure what you are doing.
