Yes this is what confused me to, as it does not run in kernel mode and therefore should not be able to crash my PC. I ran steam as admin sometime ago, cause this fixed an issue with csgo being capped at 30 FPS, however this was on a different device and right now neither steam, nor CSGO or CS2 runs with elevated priviliges.
I have never suffered from this in anyother game, from CS, to Rocket League, FIFA, Valorant, RDR2, GTA V, Far Cry or anything, so the issue should definitely be within CS2.
I do not overclock, but I will check my graphic drivers. I will not reinstall windows, as I have a bunch of shit on this device. If I cant get this fixed without overhauling my entire machine, I'll be quitting the game. :'( Thank you tho boss.
