How To Tell If Motherboard Is Bad

How To Tell If Motherboard Is Bad 1

The motherboard is an integral component of laptops and computers. After all, it’s here that other crucial electronic components, including graphics cards, the processor, ROM, RAM, hard disk drives, CMOS, and PCI slots, get connected. Therefore, any issue with the motherboard affects these vital components and affects your computer’s overall functionality. 

Quick Answer

With this in mind, you must be able to determine when your motherboard is experiencing showing failure symptoms. This can enable you to quickly think of an appropriate solution to avoid more severe complications in the future. Some of the common symptoms of motherboard failure include the following.

Blue screen of death.
Power supply disruption.
Physical damage to the hardware.
• Recurring beeping sounds.
• Random reboots.

If you notice any of these signs, there might be an issue with the motherboard. Without further ado, here’s a more in-depth look at these symptoms of a faulty motherboard. 

Blue Screen of Death (BSOD)

The blue screen of death can be caused by various reasons, including installing third-party driver codes on your computer. However, this issue can also be due to problems with hardware components such as the motherboard, hard disk drive, and RAM. To know what caused the blue screen of death, you should search the error code on Microsoft’s website or Google. 

If the error code is linked to an issue with the motherboard, you should try troubleshooting it to see whether there’s any improvement. When the troubleshooting error is always displayed, this is a clear sign that there might be an issue with your motherboard. 

Disconnect Every Component Other Than the Power Supply Unit 

If you want a more technical approach to confirm your motherboard is still fully functional, start by disconnecting all the other components besides the power supply unit. It’s an accurate approach because disconnecting components such as RAM, HDD, CPU, and peripheral gadgets such as USB drives or keyboards allow you to focus solely on the motherboard

After disconnecting the motherboard from the PC, put it over an anti-static material. Plug the power supply cables connected to a power source to the motherboard. Consequently, switch on the motherboard by jumping the power on pins on the front panel header of the motherboard. 

If your motherboard switches on and is either making beeping codes or flashing lights, it indicates that it isn’t dead. This means the issue could be due to other connected components, such as the RAM.

Inspect the Hardware for Physical Damage 

Another effective way to determine if your computer’s motherboard is bad is by inspecting it to look for physical damages. As you do this, your focus should be on the motherboard’s CPU sockets, header, and DIMM slots. Many things can result in physical damage to the motherboard, from accidental power surges to poor handling

If you suspect your motherboard is bad due to physical damage, here are some things to check during your inspection.

Check for Bends or Fractures 

When inspecting the motherboard, you must check the pins and slots to confirm they aren’t bent or loose. If there are minor damages, you can quickly repair this issue at the local repair shop. But if the motherboard has noticeable cracks, this isn’t something that you can’t fix. Therefore, you’ll be forced to invest in another motherboard to continue using your computer. 

Burned Spot on the Motherboard 

The sight of a burned spot on the motherboard is also another sign that all might not be well. This burnt spot might have happened due to a short circuit when running your computer. And if there’s a short circuit, your computer will stop working immediately, leading to the motherboard’s quick death. 

Bulged Capacitors 

You can also use capacitors to determine whether the motherboard is fully functional. This is because capacitors are vital in handling power spikes to safeguard the motherboard from possible damage by preventing a sudden and high power surge. If the capacitors are swollen, they might not be fully functional, exposing your motherboard to voltage spikes. 

Water Damage 

The risk of water damage is also another common reason why the motherboard might become faulty. This problem is especially common in computers with small stickers that can quickly get discolored once it comes into contact with a lot of moisture. Therefore, you need to inspect your motherboard when it starts experiencing issues to tell if there’s water damage. 

Listen for Beeps 

Does your computer produce a beeping sound when turning it on? If yes, this is a sign that the boot-up process isn’t going on smoothly and that there’s a hardware issue. You’ll be happy to know you can effectively determine whether your motherboard is bad by closely listening if it produces beeps when switching on your computer.

Usually, a faulty motherboard will produce a single beep, followed by three, four, or five beeps. In contrast, a problem with the ports typically generates four beeps and consequently other two, three, or four beeping sounds. Both these cases are a clear indication that the motherboard is indeed faulty. 

Random Reboots 

If your computer randomly keeps restarting itself, it is another indication that the motherboard might be faulty and nearing death. However, this issue can also be caused by many other factors such as hard disk error or virus attack. Therefore, you need to first inspect the hard disk and the presence of viruses before making a conclusive decision. 

After confirming that the issue isn’t caused by a virus or hard disk error, you can confidently determine that the motherboard has a problem. 


Because the motherboard plays a crucial role in interconnecting all the computer components, the slightest issue affects the PC’s overall functionality. This is why you need to take time to familiarize yourself with the various reasons that might result in the failure of the motherboard. Only by doing this can you know ways to resolve the causes of motherboard failure quickly. 

This blog post has eased your stresses if you were unaware of how to identify that your motherboard might be faulty. But since you now know these valuable insights, you can quickly pinpoint a defective motherboard and get it repaired on time to safeguard it from further damage.
