I have installed two GTX 580's in SLI in my ASUS P8P67 Deluxe mobo. The issue I am having is that one cards video output is active from post until just before windows login, then it goes into sleep mode. The other card is in sleep mode until until windows login, then it becomes active.
Anyone have an idea as to what is going on?
