《The most common motherboard problems, and how to fix them》​

Not enough power​

Yes, listing “check the power” as the first step in any guide is a bit cliché, but it’s an absolute must here as motherboards have not just one power connection but two.

Make sure both plugs are fully seated and properly matched with the correct power supply cords. This will solve many issues, particularly those that crop up when installing a new motherboard for the first time. You should also consider running hardware and utility diagnostics if it is possible to do so on your PC, such as the Intel Processor Diagnostic Tool, CPU-Z, and PassMark Performance Test.

Improperly installed components​

Components can cause a motherboard to malfunction if they’re not properly installed. In some cases, your computer may not even get through POST (a self-testing mechanism employed by PCs during boot-up) or even turn on. Potential culprits include the processor, video card, and RAM.

A short circuit​

Examine how your motherboard is installed. Check that you used the standoffs that keep the motherboard from contacting the case and ensure that any unsupported portions of the motherboard haven’t bent toward the case’s interior. Also, check that all internal wires are properly shielded with a rubber or plastic exterior. Learn more: Click Here

No case power button connection​

The power button on a computer’s case connects to the motherboard through a small, thin two-pin wire. Without this important but easy-to-miss connection, your computer won’t start. That’s because the motherboard never receives the command to do so if you press the power button when the wire isn’t connected to the proper pins on your motherboard. Learn more: Click Here

To solve this issue, you’ll need the manual to confirm where the power button connector goes, and you (might) need a magnifying glass to properly align the connection with the pins. If you can’t find your manual, your motherboard’s manufacturer should have a PDF version of it on the company’s site. Just search for your motherboard’s model number. Learn more: Click Here

UEFI/BIOS hardware incompatibility​

If this happens, your computer might refuse to boot your operating system after POSTing, or it might not POST at all. Fortunately, there is an easy solution to this issue. You’ll take a step backward by re-installing the old hardware you had disabled to troubleshoot your problem. When you get your computer back to that status, reboot it. Once the old hardware’s in, you can boot your computer, go to your motherboard manufacturer’s website, and find the latest BIOS/UEFI version. After installing the latest BIOS/UEFI version is complete, you can re-install your new hardware. Learn more: Click Here

Conclusion​

There are a few extra steps involved when you’re trying to troubleshoot a motherboard compared to other tech issues, but it’s a crucial skill to learn if you plan to build and repair your PC. The experience you gain by replacing your motherboard gives you the potential to use the same computer for a decade (or more) by replacing the internals when necessary.
