The title says it all in a nutshell. I go to faceit, find a match and start cs2. It launches the game but freezes before cs2 screen(the yellow one) and system reboots itself. It wont change, havent figured out whats wrong.

I had before win10 and two errormessages, which I changed to what faceit ac client required - but no change. The errormessages wanted me to change some uefi and reboot settings from bios - which I did.

Now I have win11 and haven't changed anything. Checked every update from win11, gpu etc. Dunno why it cant start the cs2. I have asked from faceit and valve and they didnt know also whats wrong. This might be my last change to get it work with this setup.

Cs2 works fine. Theres nothing with that. Does this sound familiar to anyone?
