Title says what the issue I'm having, the PC just shuts off when in-game. I can't find anything in the Windows event logger that helps. Any stress-testing I run, it passes without any CPU or GPU faults.

What I have tried:
  • Got an error when trying to stress test the cpu with OCCT, fixed it by increasing the voltage by 0.1 from auto in bios.
  • Fresh install of windows
  • Updated BIOS
  • "sfc /scannow" and "dism"

Specs
CPU: i9-10900k
GPU: 3090
RAM: Corsair Dominator RGB DDR4 3200MHz (96GB in total)
PSU: Seasonic Prime Platinum 1300

There are no overclocks in use. For some reason it only happens in game. Temps are really good when gaming so it can't be that. I see no spikes in either CPU or GPU temps or in usage when the crash happens.
