So I finally received my new Sapphire HD7970GHz today. Removed my old 6950, put in the HD7970. Start up the computer, the "Sapphire" logo on the card lights up and the fans start spinning. But absolutely no video output. All 16 PCI-e connecters are plugged into the card and seated properly. Card is seated properly in PCI-e slot. When using my i5's integrated graphics, I get video signal, and Windows Device Manager shows "Unknown Device" and that the drivers are not installed. I tried completely removing all the old AMD display drivers from my system with Driver Sweeper and did a fresh install of the latest version of CCC. Every time I try to install or uninstall anything with CCC, it will says "Completed (with warnings)" but it doesn't tell me what those warnings are.
...is this card DOA? Any suggestions on what else to try before I contact Sapphire? Specs are in my signature, but ask if you need any other information
