Windows 7 Ultimate
 
 
Monitor not detected

I'm running into this and issue and I can't peg down a cause. I recently updated my Vista HTPC to Windows 7. When booting up I can get into the OS, but the screen goes black shortly after.

I have tried two monitors: the Panasonic plasma just goes black and when I try Samsung Syncmaster LCD it looks like it's searching for digital, then analog sources.

I have an Nvidia 8400 GS card and I've tried both the 191.07 and 195.62 drivers. I've also let Windows install the drivers after uninstalling the Display Adapter in Device Manager in Safe Mode.

When I start in Safe Mode I cannot recreate the issue. I tried uninstalling/reinstalling the drivers in Safe Mode.

Thanks in advance for any advice you can give.
