Hi,
Got a problem here that I've been scratching my head over for a while. I purchased a PowerColor Radeon R9 280X and when I install it in the PCIe x16 slot of my DH67GD, the system will not post nor output any video. The onboard video does not output anything in this case, either. This is the 2nd card I've had the problem with, I RMA'd the 1st card back to the seller and received a replacement. My older PowerColor HD 6770 works just fine in the same slot, and the onboard video works just fine either with no video card installed or with the HD 6770. With the R9 280X installed I cannot <F2> into BIOS config, no video comes out on any port I can see, and despite LEDs being on and fans spinning on CPU, case, and video card I see no indication that anything is happening. I've also tried using the BIOS Config jumper on the motherboard to force the system into BIOS config screen, but no luck when the R9 280X is present. Installing all the latest AMD drivers didn't affect anything, nor uninstalling all video drivers and using default Microsoft inbox drivers. Any suggestions?
Feels like a compatibility issue between the R9 280X and something else, but I can't tell if it's with the i7 or the mobo/chipset.... I saw a similar discussion on another thread, but the card in question was an XFX R9 280X.
