Try droping down in drivers. Nvidia has all the older drivers on it's web site you have to search for them then unistall the one you have and then let windows run the video so you have a GUI and then re-install the driver you used before if you have updated the driver after you updated Vue. It takes 10 to 15 mins total. But then I am not sure with win 7 that and Vista where a big mistake by Microsoft. But it's about money with them not quality.

Good luck.
