I've been having a perpetual issue with Unity games crashing my PC. This has been going on for almost a year now, starting when I got my PC. I have rebooted my computer countless times, I have factory reset my computer and redownloaded the OS from the disc, and I have reset my BIOS more than once.

The problem still persists.

Whenever I play a game that runs on the Unity engine, after a seemingly random amount of time(usually between 10-20 minutes), my computer will simply shut off, and then reboot. This is consistent for every Unity game I have tried. Examples include Rust, Phasmophobia, and Superliminal. The crashing symptoms are consistent between all three games.

My computer specs are as such:

Motherboard: B450 Gaming Plus (MS-7B86)

Processor: AMD Ryzen 5 3600 6-Core Processor, 3600 Mhz, 6 Cores, 12 Logical Processors

GPU: AMD Radeon RX 5700 XT

4 8GB sticks of DDR4 RAM (Corsair Vengeance LPX)

OS: Microsoft Windows 10 Home

Power supply: Corsair TX650M
