Pc restarting after closing a game

Before assuming it's a hardware issue, it's a good idea to also test with an older Nvidia driver.

Try one from at least 3 months ago.

Search and download an older driver from the link below.

https://www.nvidia.com/Download/Find.aspx

– Under "Windows Driver Type", leave "DCH" selected.

– Under "Recommended/Beta", leave "Recommended/Certified" selected.

You will need to use DDU again to remove the current driver. I suggest disconnecting from the internet during the entire procedure.

See if the system will work stable after installing the old driver.

If you have GeForce Experience installed, temporarily disable the automatic driver updates in the application settings.

If the problem persists even with the older driver, I suggest you use the free MemTest86 tool for a deep check of your RAM.

The deep scan can take a long time, depending on how much RAM you have. So do it at a time that suits you.

Feel free to send a photo of the test result.

Regarding testing the GPU, it is recommended to test on another device if available. There is no reliable tool for testing GPU via software.

I've had cases where GPU testing software didn't indicate any problem with the GPU, but in fact, there was a problem with the GPU.

With the clean installation i did in mind, should i try the older driver first ? or install the most recent one ?

In your case, try with the old driver first. If the problem persists, you can install the latest driver without having to uninstall the old one using DDU.

I installed the old driver: same problem arised.

I also did the memtest, it found nothing.

It seems like there's a problem with the GPU itself.

Download the free version of the OCCT tool from the page below and see if it detects any problems with the GPU.
