I've just about gone insane trying to deal with this issue.
I have a:
R9 390
i5 4690k
ASUS Z97-a motherboard
And XFX 750 watt power supply
My computer will randomly crash to a black screen and occasionally show a error saying "Thread stuck in device driver".
It seems to work fine when i remove the video card an run on the integrated graphics on the CPU
I have tried reinstalling the video drivers, updating the motherboards BIOS, changing the PCI slot, nothing has worked, and i've run out of ideas
