I have read the other threads on getting a black screen and none of them seem to help me. I know that i installed the GPU correctly/routed it power since when i turn my PC on, the GPU's fan starts spinning for about 5 seconds and then stops. After this there is the regular dull hum of the CPU and nothing happens on my screen. I have connected the GPU to my monitor with a DVI-D. I tried un-enabling the integrated graphics on my hard drive and then installing the card, only to get the exact same result. I also know its not my power supply, as i installed a brand new 500W EVGA Supernova recently, and my computer works when the GPU is not in. Should I try installing my GPU's drivers and then installing the card? Any help guys?
