Upgraded to a GTX 580 - no video signal on boot
- by MGOwen
I have:
New Corsair 550w PSU (should be more than enough)
AsRock H61M u3s3 mobo (with latest updated BIOS)
Just replaced my faithful HD 7790 GPU with a refurbished EVGA GTX 580 1.5GB. When I boot, it sounds like the PC boots to windows, and the 580's fan is spinning, but I can't get any video signal from the card.
Old card and integrated graphics still work fine (when I replace and use those instead).
I am using the DVI ports on the card with a DVI-VGA adapter until I can get my hands on a mini HDMI adapter tomorrow.
Anyone ever heard of a GPU needed something special to make the VGA signal work? Hold down a key on startup or something? I can't even find a manual for this card.
