Hello, I've has this minor problem with my Asus GTX 670 for some time, but its suddenly become a big problem. I cant remember when it started, but it happened gradually; On booting up my screen remains blank until the windows login screen appears, the screen also remains blank if i try and enter the BIOS, this happens on both DVI, HMDI and VGA (with an adapter) on both of my monitors and both of the TV's in my house. For an unrelated reason I cleared CMOS on my Maximus V gene after which the screen remains blank even after the login screen appears.
I've narrowed the issue down to the GPU as i'm now running fine on my iGPU (BIOS appears on that too), and all my other screens are working. I have no idea where to start with this issue so i'm turning to this forum to try and help me avoid no doubt a lengthy RMA.
What I've tried:
Display set to PCIE in BIOS
GUI Boot is enabled
Different ports / monitors
i7 3770K @ 4.6Ghz, Corsair H100i, Asus Maximus V GENE, Asus GTX 670 @ 1140mhz, Corsair Vengeance 8GB @ 1800mhz, Crucial M4 512GB, Xonar Essence STX, Corsair AX750, Corsair 650D
