Hello,
I installed a new HD 7950 and windows won't boot; it gets stuck at the BIOS options screen. The board gives me an E6 code which is "Started connecting drivers." Thus far, I have tried uninstalling all Nvidia drivers with my GTX 470 plugged in then downloaded Catalyst Control (and I think the latest AMD drivers). Reinstalled the HD 7950 and the system still freezes at the BIOS screen. When I reinstall the GTX 470, everything works fine. Any suggestions?
System spec:
DP 55KG board
i5-760 CPU
Corsair TX 750w PSU
128GB SSD
Windows 7 64-bit
