No I think you are misunderstanding.
When this happens, I can't get to a safe mode, I can't see ANYTHING on the screen as SOON as the computer powers on. I can't get into ANYTHING, I have to shut down and do what I said to get it to work.
I am at the same refresh rate I've been at since I built the computer, and all my nvidia drivers are up to date.
Are you waking your computer up from sleep mode - or from a hard start. I'm running Win 7 RC - and had a similar problem waking up from sleep mode. I ended up disabling sleep mode - and the problem went away. My monitors still go into screensaver - but my PC is either on normally - on powersave mode - or off. No sleeping for my PC.
