Troubleshooting Hardware Related Issues
If troubleshooting the software related issues didn’t work, then troubleshoot the hardware related causes, which are overheating, irregular power supply and hardware failure.
Solution 1: Check If The Computer Is Overheating
The first thing you must check when your computer randomly turns off is if the computer is overheating. Overheating is the most common cause of this issue. If you find that your computer is overheating, then you have found the culprit of the problem. Now, you would need to check why your computer is overheating.
Caution: Follow the steps given below by yourself, only if you are skilled enough to handle hardware components. Else it is advised that you take the PC to a professional computer repair shop and have them follow the steps.
Open the CPU cabinet and check if there is any dust inside. If yes, then carefully clean the dust with a dry cotton cloth.
Next, check if the cooling fans are obstructed or if they are broken. If the fans are obstructed by something like wires or dust, then remove those obstructions and check if the fan is working. However, if the fan is broken then you will have to replace it.
Solution 2: Check For Hardware Failures
If you have recently installed a new hardware component, then you should remove it (if not essential) and then check if the problem gets resolved. If some of your hardware components fail, then you can face this type of issue.
The hardware components that you should specifically check for this issue are the RAM, motherboard, hard drive, and the graphics card.
Solution 3: Check The Power Supply
Another common cause of this issue is an irregular power supply. If you are using a UPS, then try plugging your computer directly to the power source and check if you still face this problem. If the problem gets resolved, then the faulty UPS was causing this issue and replacing it should fix this problem.
Now, if you don’t have an UPS and rather power your computer directly, then you should check if the power from the power outlet port is unable to power the internal PSU properly. Check if the power is fluctuating in your home.
Also, check if the plugs are loose or if the wires are torn or burnt that can cause irregularity in the power supply.
So, now you know what to do in case your computer shuts down randomly again. The above troubleshooting methods should help you fix this issue so read them carefully. As always, feel free to share your thoughts on this article in the comment section below.
