Hi.
After updating the BIOS, chipset, and all relevant drivers, conducting stress tests, and cleaning your computer, the possibilities are narrowing down. However, the issue persists.
Unfortunately, unexpected reboots may be attributed to a hardware problem, specifically with memory or CPU. Nevertheless, let's explore all potential solutions before drawing any conclusions.

Please try initiating a clean boot to ensure that only essential system resources are started, and thoroughly check for conflicts between software.
Here is a guide on how to perform a clean boot in Windows 11:

Given that this issue occurs primarily during gameplay, consider repairing the game files through the launcher or reinstalling the games to see if the problem persists.
Additionally, use the Display Driver Uninstaller (DDU) app to remove your video driver and all its remnants, and then reinstall the most current driver available for your device from the manufacturer's website.

If none of the above resolves the issue, you can consider using Driver Verifier to force the system to create a BSOD if a problematic driver is causing the issue:
*Create a system restore point. This will allow you to roll back your computer to a previous state if a problem occurs.
-Press Windows Key + X and select "Command Prompt (Admin)."
-Type "verifier" and press Enter.
-Select "Create standard settings" and click Next.
-Choose "Automatically select all drivers installed on this computer" and click Finish.
-Restart your computer.
After your computer restarts, Driver Verifier will begin checking the selected drivers. If Driver Verifier finds a problem with a driver, it will display a blue screen of death (BSOD). If you get a BSOD, write down the error code and restart your computer. Right away, you can uninstall the problematic driver or update to a newer version.
However, it's essential to be aware that Driver Verifier can potentially make the system unstable. I recommend using this as a last resort before considering a hardware defect. If you lack experience with Driver Verifier and feel uncomfortable using it, seek assistance from a qualified technician to avoid unintended complications.
