How To Test Motherboard Failure Symptoms Signs?

If a human succumbs to any disease, then there will be some kind of common symptoms. Similarly, the motherboard also starts to function slowly, and the user faces some kind of unusual activity. If you still ignore it, then you cannot revive the bad motherboard. That is why you need to know the symptoms and signs of motherboard failure and so that you have enough time to take preventive actions.

I. Visible Damage

The motherboard is very exquisite. It is made of thousands of miniature capacitors and other electronic components. To inspect if any of these components are damaged or not, first turn off your computer and open it. Don’t touch any of them with pressure as it may displace the components.

If you get any burning smell, then shut down your desktop immediately. It may be a result of overheating. So, search for the damaged or burned components and go to the repair shop and replace the electronic components.

II. Blue Screen

If you can see that your machine is showing a blue screen or black screen or beep codes without any reason or in between your ongoing task, then don’t ignore it. It may occur from any of the hardware-related issues, I mean motherboard issues. With the error code or the warning signs, just try to find the problem initially on Google or Microsoft’s website. If you are still unable to find the reason for the screen of death or Blue screen errors, then don’t waste your time go to the repair shop and tell them to find out the reason and fix that.

III. Random Restart

If there is any software-related issue, then your system can do frequent shutdowns with error beeps. But it may also happen due to the failure of the motherboard. Initially, try to find if there is any malicious software in your system or regularly update your software and security intelligence update for Microsoft defender. After doing all these steps, if the random restarts still happen, then it is a sign of motherboard failure. Go to any technician and try to figure out the problem and fix it.

IV. Getting Slow

If you are facing some slowness for a couple of days suddenly, then it is a sign of a bad motherboard or dead motherboard or other physical drive issues or drives failure or due to software issues or due to memory issues. This means your desktop needs some attention immediately, and you need to fix it right now.

V. Unable to Detect Hardware

If your desktop cannot detect the hardware like your Video cards or flash drive or memory module, first of all, change the port and check if it is working or not. If no, then there is a problem in that port. You should replace this. Or, in the rear I/O panel, if any of the USB ports or expansion slots are not working, then go to your motherboard’s official service center and tell them to replace the whole I/O panel.

Causes For Motherboard Failure

We have already discussed all the motherboard failure symptoms above. But, you should also know the reason behind it. If you can take some precautions, then you may not face the problems. So, without wasting more time, let’s know the reasons behind motherboard failure.

I. Power Instability

If your system does not get a stable power supply, then it can easily damage it. Make sure you have used proper PSU for your system and use UPS also. UPS will save your system from power instability. Without a proper power supply or due to power surges, the capacitors or the transistors even the Video cards may get damaged immediately.

II. Dust and Smoke

When you go without cleaning your system for over a year, and your case or cabinet does not have great dust prevention measures, maybe there is no dust filter in place, then the motherboard or other components are covered in dust. Dust also covers the VRM heatsinks, chipset heatsink. You will even get dust on top of your PCI-Express slot; it gets fairly excessive. And if you find something like this or maybe dirtier, you might want to consider cleaning. Smoke can also damage the hardware components of the motherboard slowly, and after a year, it may become a defective piece.

III. Heating issues

Generally, the CPU produces excess heat if you put a workload on it. If excessive heat cannot dissipate from the system, then it may damage your motherboard and cause motherboard failure. Due to modern technology nowadays, we can see the overheating warning in our system. If you face any kind of these things, shut down as early as possible and go to your technician and tell them to check the cooling system and the thermal paste level.

IV. Age

Each and everything in the world has a certain life span. If you are using your system for a long time, then it can stop any day and this is one of the main reasons for hardware failure or hardware issues. If you are using a very old machine, it will come to an end because the motherboard components’ longevity becomes very less. So, make sure to change or upgrade your parts with time. 

V. Signs of Damage from Dropping a Computer

If accidentally you drop your computer, then do a visual check if the outer case or the chassis is broken or not. In the case of a laptop, start examining the internal hardware or Physical Damages. Try to listen if there is any lose part moving inside by shaking the laptop. If your laptop comes with an HDD, then it may damage because it’s breakable. For the desktop, first, turn off the power button and unplug from the power cord and then open the side panel of the cabinet and check properly piece of hardware is damaged or not.

VI. Symptoms of a Bad Power Supply

There are some symptoms by which you can understand whether the power supply unit may be failing. There are some typical signs like Random Computer restart, noise coming from the case, etc. Generally, if you notice that light is flashing in the motherboard, that means the power supply is faulty. In some cases, your PC will not start because the eight-pin power supply which comes from the PSU can’t deliver power to the CPU. That is why you will find that the fan is moving, but the screen won’t light up. In this case, make sure to use any surge protector.
