I have 2 sapphire HD7790 Dual-X OC in crossfire and I keep getting the "Display driver stopped responding.." message only while I'm in windows. Like when I'm watching youtube, watching a blu-ray, browsing the internet. I even left it Idle for a few minutes and it still crashed. It crashed while I was typing this post. Oddly enough it never crashes while I'm playing a game.
I've tried all the fixes, the "TdrDelay" registry key fix from microsoft, disabling crossfire, underclocking and overclocking my GPUs, disabled ULPS, disabled all of the Windows 8 visual effects like Aero. Nothing works!
The last driver that worked was 13.11 BetaV1. Everything after that crashes. Sometimes the screen will go black and stay black or my PC will restart. Here are my specs:
MB: Aus P8-Z68-V/GEN3 (Bios 3603)
PSU: Corsair GS600
RAM: Kingston Genesis 16GB DDR3 1600MHz
HDD: OCZ Vertex 3 120GB
