I installed my GTX 750 graphics card and downloaded drivers but the screen is black.

I have 2 graphics cards and one is a AMD radeon something. The monitors connected to the ATI are working fine, but the monitor connected via HDMI to the GTX is not turning on. When I unplug the HDMI from either end, the screen starts cycling from HDMI to VGA and repeats. Once both sides are plugged in, it stops cycling and goes black. PLEASE HELP!

try plugging it into a different port on the card and see if it helps... the port could be physicly broken on the card... either way I would return it and get a 2 gig 750 ti(750 ti is a lot better than normal 750)
