Problem started maybe 2 weeks ago, sometimes it doesnt happen at all. I suspected the cpu overheating so i reapplied thermal paste. CPU temps a bit high but still ok. Maybe it is a failing psu? Gsync is disabled. Monitor cant be restarted after problem occurs, it just boots but nothing happens, have to restart the system. Any ideas?
