Are there any entries in the Windows system logs ?
Well, i'm not quite sure where to look.
I see a kernel-power-failure (improperly shutdown), because of the reset i had to do. That's about it.
I could be looking in the wrong place though..
I did found out: if i set the GPU (Gigabyte GV-R928XOC-3GD) fan to 100%, i get NO crashes..
The weird thing is: temps don't go over 50 degrees Celcius anyway..
But if i go below 75%, even if i underclock: it will suddenly blackscreen without warning.
Usually when playing video or switching active screens, etc.
So, it could be a sign the card is defective.. Maybe it will be fixed by an aftermarket cooler?
