Hi r3n311,
Welcome to Vista Forums!
Assuming you are using the correct drivers for the card and your version of Windows, I'm extremely tempted to suggest if the old NVidia drivers worked fine, just revert to them:
Restore a driver to its previous version even if it is generally recommended to use the most updated drivers available.
Why are you updating the drivers? Because you do so periodically and noticed new ones were available or because you were having some other problem (if so, what)? Where did you get the new drivers - directly from the NVidea website or elsewhere (if so, where exactly - the website URL if you have it)? If you got them from Microsoft Update, then definitely revert to the prior version.
If you insist on using the new drivers and they are appropriate and obtained from a reputable source (the NVidea site or the computer manufacturer website are the only two you should consider), then download them again to make sure you didn't get a corrupted file and install them again (and triple-check to make sure they are appropriate for the card and your version of Windows). Then go to Start / Control Panel / Device Manager and verify that the drivers are properly installed with no errors and show they are working properly.
Try to play with the settings in Control Panel / Personalization - changing themes, color/appearance settings, DPI settings, resolutions and anything else that can be configured to see if that helps. If not, check with the computer manufacturer to see if there are driver updates for the monitor - if so, install them and that may resolve the problem. Also, make certain Windows Update is totally up-to-date with the latest SP and every critical or important update available - the new drivers may require something in an update that isn't installed.
Other than that, I'm just about out of ideas. But post back anyway (in either case) and I'll do more research and see what I can come up with. Please include the manufacturer, make, and precise model of your computer.
I hope this helps.
Good luck!
P.S. If nothing here worked and you have no specific reason to need the updated drivers (like some software that needs them), then I personally would revert to the ones that worked and accept that you may not be able to upgrade with this version. Perhaps a later update will work better or perhaps you may need to stick with the ones you have that work properly.
