6. Check the CPU temperature

check for overheating issues

In some cases, your CPU or GPU may overheat and that will lead to shutdowns. Namely, your motherboard is programmed to shut down everything in order to prevent serious damage to your CPU.

This especially goes for laptops that are most of the time lacking an adequate cooling system for intensive gaming.

You can check system temperatures with 3rd-party tools or just casually touch the backside of the laptop.

If the temperatures are alarmingly high, you’ll need to take some action.

  • Clean fan bay on laptops or CPU cooler on a desktop.
  • Change the thermal paste.
  • Use the cooling pad of some kind to reduce heating.
  • Change overclock settings to default.

In case your notebook/PC is in warranty, we advise you to take it to your supplier and let the professionals do the cleanup.

7. Update BIOS

Even though BIOS updating is not advisable, especially for beginners, sometimes it’s required. If misused, BIOS update can cause a lot of problems and most of them are fatal to your PC.

Some motherboards offer special update tool featured in BIOS settings. If you have a new motherboard, you’ll have an easy time updating.

However, those of you with the older configurations have a much harder task.

Make sure you gather all the information before performing the process. Moreover, if your motherboard is up to date, don’t upgrade it.

Another thing worth checking is your HDD. If your HDD is corrupted or it has damaged sectors, you’ll probably encounter a large variety of problems.

Most of the time the system won’t boot, but it may as well be related to sudden shutdowns. For that purpose, you can use 3rd-party tools and scan the disk (like HDDScan), or use the built-in tool and do it internally.

For starters, the built-in tool will serve you right and here is how to use it. On the other hand, if you are seeing Unknown, Caution, or Bad, your hard disk has some issues.

Of course, you can always scan your HDD with one of the best tools from this great list!

9. Perform a clean reinstall

At the end of the day, the clean reinstallation of Windows is the most viable solution. Of course, if the hardware isn’t the instigator of the uncalled shutdowns.

You can use Media Creation Tool to easily obtain installation setup for either ISO DVD or bootable USB.

Have in mind to back up your data from the system partition before the process commences. Moreover, take good care of your license key.

The process is not as hard as it was on some of the previous systems so you’ll be able to finish in two hours.

That should wrap it up. We hope you’ll find these workarounds appropriate for the issue.

Finally, all you can do is try since Microsoft is the one that should address this issue with more enthusiasm. In case you have any suggestions, alternative solutions, or questions, don’t forget to tell us in the comments.
