So...are you running Nvidia drivers? Lately there seems to be a lot of problems with Nvidia cards both integrated and standalone.
In my opinion, I upgrade drivers on anything only if I start having problems and can positively trace the cause back to that component; I have see too many of this kind of thing where buggy upgrade drivers cause as many problems as help. "If it ain't broke, don't fix it".
> Are you sure that your video card is causing the problems? Did this start immediately, like within 10 minutes, after installing the updated drivers? Make totally sure the the video drivers are the problem and not something else.
> If so, roll back the drivers: try a system restore to a date immediately before this started. OR:
> Get on the Nvidia website, and download the drivers that were originally on your laptop; sometimes these manufacturers will have older drivers posted, especially video cards. Look for a video card remover program supplied that will auto-remove the drivers first, then install the original ones. You can always enter Explore, find the Nvidia folder, and manually remove the drivers in Safe Mode, but be very sure that you have the correct drivers to immediately reinstall on a CD or thumb drive!!
> If you are a very lucky person and have the drivers on a CD that came with your computer, use that to uninstall the old drivers and reinstall the originals.
> If worse case happens and nothing works, try a refresh reinstall, but do this only as a last resort.
