Signs that your computer's motherboard is about to fail
The motherboard (mainboard – or motherboard) is quite an important component in a PC. Its unexpected failure will cause you a lot of trouble.
The motherboard (mainboard or motherboard) is a very important part, it is responsible for connecting and controlling all the activities of computer hardware components. Since it is a "connection", a defective motherboard will cause a loss of connection between the components, causing the computer to stop working locally.
In this article, we will take a look at the signs that your computer's motherboard is about to break, thus quickly preparing a timely repair or replacement solution.
Determine if the computer's motherboard is defective or incorrectly configured
Before you assume that your motherboard is faulty, you need to make sure that it is not just misconfigured. If you notice a red light blinking on the motherboard's case, the problem is most likely due to a problem with the motherboard configuration. If you have not adjusted the settings on your motherboard, check that the PSU, CPU, RAM, and GPU are properly configured and compatible.
If the motherboard and its components are not misconfigured, then there is probably a problem with the motherboard itself. To confirm your suspicions, you should see if the symptoms listed below are occurring on your computer.
1. The motherboard beeps when the computer starts
When something goes wrong with your motherboard, your computer will try to let you know about the problem through a series of beeps - also known as POST beeps. However, computer component manufacturers currently do not have a common standard set of beep codes, so you will need to determine how the motherboard BIOS manufacturer uses the beep code to "decode".
If you can "decode" the beep on the motherboard and determine that this is what is happening with your computer, then prepare to replace it. However, there are also cases where, although a beep is heard, the problem is not necessarily with the computer's motherboard, but rather with other hardware components.
2. The POST process failed or failed
POST (Power On Self Test or Power On Self Test) is a process performed by the BIOS before your computer starts. If your computer's motherboard is faulty or damaged, your PC will not be able to start POST. However, note that this phenomenon can also be caused by improper or incorrect installation of hardware components. If POST does not run, the problem is most likely with the computer's main unit or power supply.
3. Flashing light phenomenon on the motherboard
In case you don't know, manufacturers often equip the motherboard with a few extra signal lights. Based on the light signal, you can quickly identify what problem is occurring on your computer.
Basically, most computer motherboards today are equipped with four red LEDs and are clearly labeled. Specifically, BOOT indicates a hard drive/SSD problem, VGA indicates a GPU problem, DRAM indicates a RAM problem, and CPU indicates a CPU problem.
If the signal light on a component is on and you have checked and fixed the problem with that component, but the motherboard still shows a problem light that cannot be fixed, then there may be a problem with your computer's motherboard.
4. Signs of physical damage to the motherboard
Last but not least, any physical damage to your motherboard is a clear sign that it may be broken. Look for broken, bent or dented circuits, breaks, cracks, lumpy capacitors or electrolyte leaks. However, water-related damage is often difficult to detect, but look out for color changes or burn marks on the motherboard that may be the cause.
Also, check if the motherboard socket area on the case is holding the motherboard in the correct position. If they are not properly aligned with the slots, your motherboard may be shorting out. Try disassembling and reinstalling your motherboard.
If you notice that there is a lot of dust and dirt on the motherboard, clean it with a can of compressed air and restart the computer.
5. Try replacing the CMOS battery with a new one
Before you assume that your motherboard is defective, try replacing the CMOS battery.
Some motherboard "errors" are often caused by the "dead" CMOS battery. Therefore, search the Internet for information about the motherboard you are using and determine which type of CMOS battery is suitable for purchase. Then replace the old CMOS battery with a new one and try to restart your computer.
6. Replacing the RAM and removing the graphics card still didn't help
It's not uncommon for a computer to fail to boot, which is often due to a RAM or GPU issue. You can determine if your computer is in this situation by trying to remove the GPU and a stick of RAM (if using 2 sticks of RAM). If the computer fails to boot, try replacing the RAM with another stick.
If the computer still won't boot despite removing the RAM and GPU, it indicates that neither of these components is the cause of the problem you're experiencing.
7. Hardware components will continue to function normally if you install them on a different motherboard
If your computer system works again by using a different motherboard, it is likely that your previous motherboard is damaged.
Using a different motherboard for this general test is useful because it allows you to quickly determine if the old motherboard is damaged or that a hardware component not part of the motherboard, such as the power supply or CPU, is having problems.
Replace the motherboard
Generally, if your motherboard is broken, it is extremely difficult to diagnose. Although you can still solve problems with your computer's motherboard, it requires you to have extensive repair skills and knowledge.
So, if you are a regular user and find that your motherboard has a problem, you should check whether it is still under warranty or not. The good news is that nowadays many motherboard manufacturers offer quite "generous" warranty terms for the long term, so you can definitely swap in a new motherboard right away.
The advice to you here is to replace it with a new one and not focus on repairing it if the motherboard is broken.
