I have an EVGA GTX 960. It is a year and a half old. Basically I will be gaming or watching a video, and it will usually get really sluggish, like freezing and unfreezing randomly. Then eventually it just completely freezes and whatever noise is playing at the time of the freeze just distorts to an infinite glitched ear rape sound. Then if I do nothing the pc will restart itself. It boots on integrated graphics (shitty resolution) and says in device manager - display adapters that my 960 "has problems detected so it stopped working (code 43)". I have updated drivers, deleted them, reinstalled them etc... It wont help. This does not happen immediately I could play for 5 hours with no problem OR it happens after 30 minutes. It is completely random. But if I hold down power button and hard restart it always fixes it instantly. Device manager says my GPU is fine drivers = fine. But then I am just waiting for it to do it again. Idle GPU is like 50 Celsius and while gaming is like 57 Celsius. Any idea how I can fix this or what is causing it? Performance is fine before crash but then the glitches start happening and a minute later the PC is frozen. Sometimes it will just freeze/crash with no prior symptoms. Seems to be only when I am watching videos or gaming but that could just be coincidence.
