And if the game doesn’t have autosave or you haven’t found a checkpoint yet, all progress is lost. But no worries, the ultimate guide is here.
In this article, I’ve explained why your computer keeps restarting when you are playing games and how to solve this annoying problem forever.
Why Computer Restart When Gaming?
Your computer keeps restarting might be happening because of some power supply issue or power settings, a lousy GPU, or your GPU doesn’t meet the requirements for the game or overclocking the CPU. Dirty fans, heatsink, or old, ripped-off thermal paste can make the CPU overheat and shut down your PC.

You need to find out what’s causing this problem. Is it the CPU or the GPU? The power supply or the power settings? Or some other settings that you’ve knowingly or unknowingly changed.
Here are the reasons that might cause your computer to restart:
Game Requirements Not Met
Check the requirements of the game that’s causing your PC to restart. If the conditions don’t meet, it might be causing too much stress on the CPU, and you shouldn’t play that game without upgrading your PC.

- Click the Windows icon.
- Go to Settings > System > Power & sleep > Additional power Settings.

Don’t play third-party cracked versions of any games. Also, update the game and check if your PC fulfills game requirements.
You can reinstall the game as well and check if the issue is resolved or not.
6. Update Windows
A defected process running in the background or a temporary bug might be causing your PC to restart.
If that’s the case, check for Windows updates, update your drivers if available, and restart your PC after updating. It will stop any harmful processes and remove bugs.
7. Check PSU
If you still have the restart problem, it might be because your Power Supply Unit (PSU) is not providing power supply properly to all components.
Make sure your power supply can keep up with the graphics card. If it can but still failing, that’s because the PSU is faulty, and if it cannot, then you need to purchase a PSU that provides more power.

If the CPU gets too hot, it’ll shut your computer to protect itself. You need to prevent the CPU from getting too high temperature.
Just keep your computer desk clean, check if the heatsink is fine, ensure all the fans are working correctly, and keep them clean.

Be very careful; all your softwares and configurations you’ve made on your PC after the restore point will be deleted.
Here are the steps to restore your PC:
- Right-click the Windows icon and select Run.
- Type exe and click OK.
