So I just got a GForce XT 770 and installed it. When I booted up my PC it showed screen where you can chose to go to the Bios but then it went black and never loaded windows. I tried removing it and resetting it in the slot. This time it wouldn't do anything, in fact when I power on the computer it shuts off after about 15 seconds and then turns back on. It does this repeatedly. Does anyone know why this is happening? Any ideas how to resolve this issue and make the card work like its supposed to?
