Check For Overheating Issues

As we mentioned before, one of the reasons why your computer is shutting down randomly by itself could be that one or more computer components are starting to overheat. This heat related problem can occur if your computer is working too hard, for example if you are playing some graphically intense game and your video card's cooling fan is not working properly.

First, we recommend you to check the power supply cooling fan on the back of your computer. If it works properly, then it should be moving smoothly and quickly. To check other cooling fans in the computer require you to open your computer case. Check all of the cooling fans like CPU fan, case fan, video card fan, hard drive fan etc., make sure that none of them are making squealing sounds or other unusual noises. If your power supply cooling fan is too hot, then you may need to replace the power supply.

We recommend you to clean the inside of you computer as well, clean your computer from stuff like dirt or dust that could possibly cause the overheating issue.

Check For Malware Or Viruses

If your computer is shutting down randomly because of the software related problems, then you might want to try to scan your operating system for viruses and malware. Some viruses or other infections are designed to cause system crashes like computer shutdowns. Besides, it is always a good idea to scan your system from time to time. You can use Windows Defender (built-in antivirus program) which protects your computer against viruses, spyware, other malicious software. Or you can run any other third-party antivirus if you have one installed. To run full system scan using Windows Defender type "virus" in Search and click on the "Virus & threat protection" result.

Turn Off Fast Startup

Turning off Fast Startup feature could prevent your computer from shutting down randomly. Fast startup is a feature on Windows 10 (and also Windows 8) that provides a faster boot time when starting up your computer. It is a useful feature and one that most people use without knowing, however, some people disable it immediately when they receive a new computer with the Windows operating system. With the fast startup feature enabled, shutting down your computer might seem like you are completely shutting it down, but this is not entirely true, since it moves into a state between hibernation and shutdown. Leaving fast startup enabled should not harm your PC, since it is a Windows feature, but it could possibly cause this problem. To disable Fast Startup go to Search and type "power". Click on the "Choose power plan" result to open it.

turn off fast startup step 1

In the Power Options window, click "Choose what the power button do".

Click on "Change settings that are currently unavailable" and then uncheck the "Turn on fast startup (recommended)" option if it is enabled. Click "Save changes" to save the changes made, restart your computer and see if the problem with unexpected shutdown still persists.

Update BIOS

BIOS (Basic Input Output System) is software stored on a small memory chip on the motherboard. You might need to access the BIOS to change how the device works or to assist in troubleshooting a problem. It is possible that the hardware responsible for this unexpected shutdowns problem is having some problems and updating BIOS could fix the problem. Bear in mind that updating the BIOS is a procedure for advanced users, and if not performed properly, can cause permanent hardware damage.

To update the BIOS, go to your motherboard manufacturer’s website and download the latest BIOS version for the motherboard. There should be a manual describing how to update the BIOS - ensure that you read this carefully. If you do not know how to update the BIOS, find an expert to avoid damage to your computer.

Reinstall Video Drivers

Device driver is software that informs the operating system and other software how to interact with particular hardware. It is rather like a translator between software and hardware, since they often are created by different manufacturers, companies, or people. The driver facilitates smooth communication between hardware and software. In most cases, computers are unable to send and receive data correctly without drivers. If the appropriate driver is not installed, the device might not function properly and cause various problems. One of the reasons why your computer keeps shutting down randomly could be that your video (graphical processing unit) driver needs to be updated by reinstalling it. In this guide we are going to show you how to uninstall and then reinstall the video driver. Before going any further we recommend you to download the video (GPU) driver from its manufacturer's official website and have it downloaded on your computer or USB.

To update the GPU driver, open Device Manager by right-clicking the Start button and selecting "Device Manager" result from the contextual menu or type "device manager" in Search and click the "Device Manager" result.

reinstall video drivers step 1

In Device Manager you will see a list of devices connected to your computer. Find and expand the "Display adapters" category and right-click your display adapter, select "Uninstall device".

reinstall video drivers step 2

Mark the "Delete the driver software for this device" checkbox and click "Uninstall".

reinstall video drivers step 3

Now right-click your video device again and select the "Update driver" option from the contextual menu. You will be asked if you want to search for updated driver software automatically or to browse your computer for driver software. If you select the first option, then Windows will search your computer and the Internet for the latest driver software for your device. If you select the second option, then you will have to locate and install the drivers manually. Select the second option if you have downloaded the video driver as we recommended in one of the previous steps.

reinstall video drivers step 4

Now click the "Browse..." button and locate the downloaded driver. Click OK when selected and then click "Next", the installation process should begin.

reinstall video drivers step 5

If reinstalling the video driver could not solve the problem, then we recommend you to try to update the driver by selecting "Update driver" when right-clicked your video device and select the "Search automatically for updated driver software". Restart your computer and see if the problem is now solved.
