My PC keeps restarting when I play games

“Hello. My computer was restarting while I was playing games. After reading several threads I already changed my PSU, the video card, and the memory but I am still having the same problem. I already tested the PC using benchmark programs without any problems, the computer only crashes and restarts with games.

Why your PC restarts while gaming?

There is not only one reason that can lead your PC to fall into restarting inferno, but numerous menaces to cause a reboot. It’s really annoying, but overall, you can refer to three directions: hardware issues, system incompatibility, and low storage space.

Thus, we list some common reasons that may result in restarting while playing games.

1. Hardware problem

This might be the most common reason why your PC restarts when playing games. Some games will burn your CPU resources, so the computer will restart to protect itself from overheating damage.

Bad PSU (power supply unit)
The main component that supplies electricity to your motherboard components is the power supply unit. If it's broken or not working properly, your computer will meet reboot issues.

The incompatible GPU installed in your PC is also a potential point to force your computer to reboot while gaming.

In current computers, the heatsink is perhaps the most significant cooling component. It keeps the CPU cool while it works and does computations. If the heatsink is set to default, you will encounter a number of problems, including the need to restart your computer.

2. Incompatibility

If the PC restart appears after you installed a new Windows update or a game update, you may think about the incompatibility of the system edition and game version. Sometimes it might even cause a reboot loop.

3. Low storage space

A crowded C drive and the hard disk might always be the source of lots of PC problems, such as BSOD, computer frozen, randomly crash, etc. Make sure your hard drive or SSD has enough free space before enjoying games.
