Everything is connected properly, the motherboard is working fine and everything is as it should be seen as though i had my old gpu up and running 30 mins ago, i try my new gpu (msi hd7970 twin frozr 3gb) and nothing...i made sure all bios was up to date before i changed gpus and now my old one doesnt even work when i put it back in. Whats happening? My mobo has no video output so i cant access bios through that so im basically screwed.
