How To Troubleshoot A Motherboard? [Easy Way to Diagnose]

A motherboard is one of the most important components of a computer. Your CPU, GPU, memory, and soundcard all need something to plug into. So, how to troubleshoot a motherboard in an easy way?

When building a PC, it is usually the first thing you will buy, but it is not often talked about outside of enthusiast circles.

The motherboard is the backbone of your computer, setting the rules on what components can be installed and how they work together.

With all that responsibility, it’s no surprise that even a bit of bad luck with hardware choices can throw a wrench into an overclock or quick-and-dirty gaming PC build.

The truth is, motherboard fails, but how to troubleshoot a motherboard is something that usually needs some time to diagnose.

When your computer stops responding, and you jump to the conclusion that your motherboard is dead, there are several things to try and test.

A motherboard can be a pain to troubleshoot because it has so many components that can fail, so you don’t know where to start.

How To Troubleshoot A Motherboard?

This guide will give you a general idea of how to troubleshoot your motherboard when things go wrong, or at least what to try first before getting frustrated.

Diagnosing a Motherboard

When you troubleshoot a motherboard, the first thing to check is that all the cables are plugged in.

This seems like a simple and mundane task, but it is one of the most common problems.

It might seem silly, but spending a few minutes making sure everything is plugged in correctly will save you hours of frustration later on. To further troubleshoot a motherboard, you can

See if components are mounted properly

One thing to check is that your components are mounted properly. In particular, the CPU socket and RAM slots are places where components come into close proximity.

These aren’t likely to fail on their own, but a bent pin or a misplaced memory stick can lead to dead boards very quickly. If you find an issue with these, then fix it before jumping straight into motherboard troubleshooting.

Replace the Power Supply

If everything seems well with the components, it can be a good idea to rule out the power supply as the source of the problem.

Swap it for a new one, or replace it with an older one to see if your motherboard starts working again.

A faulty power supply that creates too much or not enough voltage can cause your system to malfunction.

Replace RAM

If possible, try swapping out RAM sticks one by one to see if some faulty hardware is the problem.

Similarly, you can try a different slot for each stick that you own. If you have two of the same brand and type, then try both of them in each slot.

Check for loose parts on the motherboard

On the subject of components, it is always worth checking that nothing has come loose from your motherboard during a move or an upgrade.

Check to see if screws are holding certain ports and sockets in place. Loose bits can cause problems from electrical damage to shorts on the motherboard.

Check BIOS settings

While you are tinkering around with cables and hardware, you may as well check the BIOS settings too.

Check to see that your boot order is correct and that it isn’t set for an empty CD drive or a faulty hard drive.

You may need to update your BIOS from the manufacturer’s website, especially if you are still using an older version.

Look for ways to update or reset your BIOS settings and see if any of them fix the motherboard issue you’re having.

Check the beep sound

If your motherboard is beeping at you, then that is probably a pretty good sign and means that it isn’t all dead.

What the beep code means will vary between different boards and BIOSes, but there are common problems that have specific patterns associated with them.

A beep code means that your motherboard is having trouble accessing and initializing a module of BIOS-encountered hardware.

The number of beeps will vary depending on the board, but a good rule of thumb is one beep for every error message.

What if nothing works?

If you’ve done as much troubleshooting as we’ve suggested here and still your motherboard isn’t up and running, then it might be that your motherboard is dead. In that case, you should consider replacing it.

Alternatively, you can also take it to your nearest motherboard repair shop to get it fixed.

This is generally easier and more reliable than fixing the motherboard yourself and can save a lot of time and effort.


Diagnosing the motherboard is a difficult task, and a lot will depend on the type of motherboard and how it’s configured, but you can make things easier for yourself by starting with simple checks that eliminate as many possibilities as possible.

Once those are ruled out, then you can get more advanced in your troubleshooting.
