Hi.

I recently disabled sli on my 780 gtx s

To see if total war Rome 2 would run better on one card..

Anyway after I did that I tried to re enable sli and my screens just go blank

After hard rebooting my PC comes back on disabled sli. I have uninstalled and reinstalled the drivers.

Any thoughts?

Bear in mind it worked fine before. And both cards work and are installed correctly..
