Yes, that's exactly what I had, a dark grey screen so my monitor was definitely still on and it wasn't asking me to check the video cable as it normally does when it doesn't detect a signal. I've seen a few posts from people having problems installing these on Windows 8 so my own advice is to avoid them and use the certified v306.97 drivers instead. These install fine on my system through the both the Windows Update and if I install them manually. Windows 8 does seem to like restarting though. How did you fix your grey screen issue, Spets? How does one bring up the options in Windows 8 to, say, use the last known working configuration as I'd like to known that in case I have this issue again. The first (and, so far, only time) it happened I had to do a refresh install and the lost all my settings and applications which then forced me to restore my Windows 7 backup. Very annoying. I would like to know how to use/recover a system checkpoint instead.
