Pc Crashes While Streaming

Didn't really know where to post this so it's right here.

Alright so the problem is this: I start streaming a game. Within 5 minutes my pc just stops doing anything. Fans keep turning, all rgb lights keep working. It just doesn't do anything anymore. I need to unplug power supply to turn it off completely before being able to restart it. Nothing overheats, that's for sure. It only happens when streamlabs and a game like Battlefield V or Tomb Raider (so like a big game) is open.

Specs:
GPU: 2080ti Inno3D

CPU: Ryzen 7 2700X
Motherboard: MSI X470 Gaming Plus
case: Sharkoon TG5 ATX
PSU: EVGA GD

anything else needed?
