PC Restarts while gaming

[Jembo]

I recently bought a Radeon radeon rx 6700 xt red devil, and today (after the pc has been running fine for the past two days since upgrading) my PC started restarting itself after a short duration of playing games as well as one game would run correctly (I could hear the menu responding to inputs and the music worked) but had a total black screen.
This issue seems to have started after I installed the newest AMD launcher and drivers. Upon removing the launcher, the black screen game worked properly but I couldn't launch the other game that was making my pc restart due to the error “DX11 feature level 10.0 is required to run the engine.” CPU and GPU temps were in the 40s-50s degrees C

**UPDATE**
same restart happened during a longer play session of GTA V 
performance was good during gameplay (100+fps) on normal settings fullscreen, 1920x180p
Unknown CPU and GPU temps 
All AMD programs uninstalled during this play
**UPDATE**
Max settings doom eternal runs fine at 140 fps average
(no restart happened during playtest)
