I have a Windows 8 64 bit installation upgraded from a Windows 7 Ultimate installation, with an nVidia card and the latest signed drivers(306.97 as of this writing, a single bundle for both Windows 7 & 8). At random the screen flashes to black for a second upon mouse clicking.

Is this a known problem, and is there a workaround?

Have you tried the beta version of the drivers? –  Ramhound Nov 19 '12 at 15:20
Nope..does it help fix this? –  Rex Nov 19 '12 at 17:11
@Rex it vastly improves the situation –  Rowland Shaw Nov 19 '12 at 20:44
have u tried reinstalling? maybe something went wrong during installation. or try a refresh (if you don't mind) and then install all drivers again –  pratnala Nov 20 '12 at 6:18
