I am a new member, hello! But I am posting a solution to a problem I had recently. It arose when I decided to get a second GTX 580 for Sli. I have the Asus P8P67 Pro B3 motherboard and two EVGA GTX 580s 1.5GB cards. On my previous Windows 7 install, I could not enable SLI. As soon as I would tick off "Maximize 3D performance" and click Apply, the nvidia control panel would crash, and the driver would go straight to hell. The screen would flash to black for a second and then I would be stuck with 800x600 res. The only solution would be to reinstall the driver. However, after many attempts to reinstall drivers and whatnot, what really solved this problem was to update my motherboard's bios to the latest version, reformat my hard drive and reinstall Windows 7. Turns out it was some sort of driver conflict. I tried Driver sweeper and "fresh" installations of geforce drivers, but that didn't help. So to any of you guys looking to upgrade to SLI, be aware that this might happen to you. Or if you already have this problem, try my approach. Note that this problem may be unique to my motherboard.smile.gif
