Make sure you have the most up to date driver for your graphics card from its manufacturers website.

You could also try booting into safe mode (F8), go to device manager and remove the existing driver. When you reboot windows should run on the default driver which will then show you if the problem is just graphics. Personally I think there is more to it than that and there may be another issue as well. Try that and a new download for the driver and let us know.
