Problem with 7 Ult X64 Recognizing 2nd Video Card
I have 2 EVGA GTX570HDs, I want to run them in SLI on my XFX 790i Ultra SLI Motherboard. i have qx9650 and 4gigs of ram. I just reinstalled windows 7 ultimate clean install. But windows 7 isnt seeing the 2nd Video card. On top of that when i activate 2 monitors which ever is my primary screen ( with start menu and all) will flicker while the 2nd screen is flicker free. When i go back to one monitor ( either of them) it doesnt flicker at all.
