Hello, I've been confronting with this problem for a few years with this problem, It happenes even when pc is Idlling, mouse freeze, Alt+Ctrl+Del not working, have to hard reboot. I had some problems with cpu voltages (had allways to hard shutdown, upped voltages, activated LLC carrefully, disabled all energy save features in bios). Cpu good temps, Vrm not hot, in aida64 test, no throttle, all ok. But these freezes still persists. please help, I've lost many hours of game play, now I save every 30 mins -1 hour manually, please help it's verry frustrating.
