I just purchased a GTX570, and have been having so much trouble trying to get this thing to work. Now I have been reading a lot of threads, and people are saying this is usually a PSU problem. I have an 850w power supply, I plugged in both PCI-E 6 slot pins to my Graphics Card, so there isnt a problem there. I uninstalled all of my old drivers too. I plugged in my monitor to my motherboard, and it works there, but not when I plug it into my Graphics Card. Does anyone know how I can fix this?
