Method 3: Overheating Issue

If your CPU runs too hot for a very long time, it may cause you a lot of trouble, including sudden shutdown, system crash or even a CPU failure. While the ideal temperature for CPU is room temperature, a little higher temperature is still acceptable for a short time period. So you need to check if your computer is overheating or not, you can do that by following this guide.

If the computer overheats then the Computer definitely shuts down due to overheating issues. In this case either you need to service your PC as heats vents might be blocked due to excessive dust or your PC fans are not working correctly. In any case, you will need to take the PC to the service repair center for further inspection.

Method 4: Faulty GPU (Graphics Processing Unit)

Chances are the GPU installed on your system might be faulty, so one way to check this is to remove the dedicated graphic card and leave the system with only integrated one and see if the issue is resolved or not. If the issue is resolved then your GPU is faulty and you need to replace it with a new one but before that, you could try cleaning your graphic card and again place it in the motherboard to see it’s working or not.

Incompatible or corrupted GPU Drivers

Sometimes the system freezes or reboots randomly because of incompatible or outdated graphics drivers, so in order to see if it’s the case here, you need to download and install the latest graphics card drivers from your manufacturer’s website. If you can’t log in to Windows as then try booting your Windows into safe mode then update the Graphics drivers and see if you are able to resolve Windows freezing or rebooting due to Hardware problems.

Method 6: Faulty PSU (Power Supply Unit)

If you have a loose connection to your Power Supply Unit (PSU) then it can cause the Windows freezing or rebooting issues and in order to verify this, open your PC and see if there is a proper connection to your Power supply. Make sure the PSU fans are working and also make sure to clean your PSU in order to ensure it runs unhindered without any problems.

A faulty or failing Power Supply is generally the cause for the Computer randomly rebooting or shutting down. Because the power consumption of hard disk is not met, it won’t get enough power to run and subsequently you may need to restart the PC several times before it can take the adequate power from PSU. In this case, you may need to replace the power supply with a new one or you could borrow a spare power supply to test if this is the case here.

Faulty Power Supply

If you have recently installed new hardware such as video card then chances are the PSU is not able to deliver the necessary power needed by the graphic card. Just temporary remove the hardware and see if this fixes the issue. If the issue is resolved then in order to use the graphic card you may need to purchase a higher voltage Power Supply Unit.

Method 7: Issue with the operating system

It’s possible that the issue is with your operating system rather than the hardware. And in order to verify if this is the case then you need to Power ON your PC and then Enter BIOS setup. Now once inside BIOS, let your computer sit idle and see if it shut down or restarts automatically. If your PC shuts down or restarts randomly then this means your operating system is corrupted and you need to reinstall it.

It’s better to take your PC or laptop to the service center where they would do this for you. Also opening the PC case or laptop can void the warranty, so continue at your own risk.

Make sure to clean dust settled on Power Supply, Motherboard, RAM, air vents, hard disk and most importantly on Heat Sink. The best way to do this is to use a blower but make sure to set its capacity to the minimum or you will damage your system. Don’t use a cloth or any other hard material to clean the dust. You could also use a brush to clean dust from your PC. After cleaning the dust see if you’re able to resolve the Windows freezing or lagging issue, if not then continue to next method.

Cleaning the dust

If possible see if the heatsink work while your PC powers ON if the heatsink doesn’t work then you need to replace it. Also, make sure to remove the Fan from your motherboard and then clean it using a brush. Also, if you use a laptop it would be a good idea to buy a cooler for the laptop which will allow heat to pass from laptop easily.

Method 9: Check Hard Disk (HDD)

If you face any issue with your hard disk such as bad sectors, failing disk, etc then Check Disk can be a lifesaver. Windows users might not be able to associate various error face by them with a hard disk but one or other cause is related to it. So running check disk is always recommended as it can easily fix the issue.

How to Check Disk for Errors Using chkdsk

If the above method weren’t helpful at all then there is a chance that your hard disk might be damaged or corrupted. In any case, you need to replace your previous HDD or SSD with a new one and install Windows again.

Method 10: Update BIOS

BIOS stands for Basic Input and Output System and it is a piece of software present inside a small memory chip on the PC’s motherboard which initializes all the other devices on your PC, like the CPU, GPU, etc. It acts as an interface between the computer’s hardware and its operating system such as Windows 10.

What is BIOS and how to update BIOS

It is recommended to update BIOS as a part of your scheduled update cycle as the update contains feature enhancements or changes that will help to keep your current system software compatible with other system modules as well as provide security updates and increased stability. BIOS updates cannot take place automatically. And if your system has outdated BIOS then it can lead to Windows freezing or rebooting issue. So it is advised to update BIOS in order to fix this issue.

Note: Performing BIOS update is a critical task and if something goes wrong it can seriously damage your system, therefore, expert supervision is recommended.
