Hi,
I recently built a new computer with an EVGA GT 640 video card. The display works fine, but as soon as I install any driver except the default Windows driver, I get a blank screen (I can only see the POST and the Windows status bar loading for about two seconds before the blank screen). I have tried EVGA drivers, NVIDIA drivers, and multiple older versions of the drivers. I thought it was a motherboard issue, but I RMA'd it and upon return, I am having the same problem. I have verified that my monitors and cables (DVI) are not broken, the GT 640 works on a friend's PC, my motherboard is compatible (ASUS M5A99FX), and I have tried two, separate hard drives after they've been freshly formatted.
Thank you for your help. I am absolutely dumbfounded by this issue.
