The process of identifying and analyzing issues with the motherboard could be complicated. As issues with the CPU, it is difficult to accurately pinpoint the root of the problem. If a computer’s motherboard is malfunctioning, it will run at a slow speed, occasionally freeze or reboot or not boot up to an operating system or not boot at all.
In addition, the system also can shut itself off or show a “blue screen of death” (BSOD). Sometimes, the computer may give the user a warning by flashing a very general error message or a sound signal or flashing a bright red display. These signals can signal a problem with the ports and the expansion slot, modules for memory or any other hardware component that could trigger extensive analysis of the motherboard.
How to Test Motherboards – Many Methods
Due to the multitude of small components integrated into the power supply and motherboard, diagnosing issues in any component is the most challenging aspect of fixing computers. You are accountable for carrying out the required study, even if technological advances have enabled you to spot motherboard issues in a more straightforward and user-friendly method.
Utilize the information in this list to isolate every motherboard issue within minutes.
Apply POST Diagnosis
If your power to the computer procedure called the Power-on Self Test, also known as POST, is carried out on the motherboard. If everything goes according to schedule, it is expected that the POST will permit the automatic continuation and complete start-up of the system.
In other cases, any problem with the motherboard may cause the POST to show the same error messages as the ones mentioned earlier.
Be attentive to all diagnostic Signs.
A problem with your computer’s hardware could cause an unplanned shutdown of the system, and the root cause could be with the motherboard. The lights, sounds, and error codes may refer to specific troubleshooting and problem-solving instructions.
It is best to note these signs as they could give you a step-by-step solution to the issue.
Use BIOS/UEFI Diagnostics
Every motherboard manufacturer includes diagnostics programs using the Unified Extensible Firmware Interface (UEFI) in their offerings. If your motherboard has issues, there will likely be a possibility that you’ll be unable to access your motherboard’s BIOS or the UEFI.
Utilizing a UEFI program that works with your computer, which could be installed onto a USB drive that can boot USB drive, is a way to bypass this restriction. Testing your motherboard is feasible, as is diagnosing issues with displays, RAM fans, and other computer components with this program.
There are instances where the problem is due to an outdated BIOS configuration. Once you have entered the UEFI, verify for any updates available to the BIOS in the meantime, and then take the time to install and download all updates. If there aren’t any updates, search for a button that says “restore” or “reset” to ensure you can restore the BIOS settings to their default state.
Change the CMOS Battery
If your computer can’t start-up in the BIOSsystem, then there’s a high chance it’s because the batteries in the CMOS must be replaced. A CMOS chip that is still in use on older motherboards can be responsible for keeping boot settings to assure that the system boots up correctly.
When the computer is shut down, the CMOS chip has to have a power source, so it can continue to function and preserve the bios settings. If your computer can start typically using the BIOS following the CMOS battery is replaced, the problems with your motherboard might be resolved. All you have to do is make sure that the time and date signals transmitted for the computer’s clock are accurate.
Reboot with Partial Components
If you suspect there’s a problem with the motherboard, it is recommended to examine every component of your computer to see if there are any issues with it. Another method to look for motherboard issues is to restart your computer with only the required components.
Take out any components that aren’t needed, like modems, sound cards, and related peripherals. Then, remove the RAM and processor and then install both. If you notice loose connections in the motherboard, you should look for them when reinstalling the essential components.
Separating from the drive can be a different option to elevate matters to another level. While you will not be able to operate any operating system without your boot drive that is your primary one, you’ll be able to view the BIOS’s entire configuration. Suppose you’re connected to another computer functioning and have a graphics card. In that case, you can make an extra step in this process by replacing parts of the Power Supply Unit (PSU) and graphics card of that computer with those components on the PC that has failed to boot.
Then, try turning on the computer with the issue. If everything works according to plan, the motherboard is working fine. In this instance, the problem most likely is with one or more components you have removed or changed. It is now possible to return the components to the motherboard to identify what is causing the problem. Think of it as a search for an outlier in the group.
