Quotethis problem is caused by a mixed set of drivers (different builds) for your graphics card. You can get this if windows updates your graphics card and you don't actually reboot before running the vendors graphics setup program. Basically, windows update attempts to install the graphics driver but it is in use so it puts it into a queue to be installed on the next reboot (not sleep). In the mean time, before you actually reboot or power cycle your machine you use the vendors update program that does not require a reboot. All is well until, some time later you reboot and windows sees that it has a update to install on the reboot and does it. Now you have a mixed build and your graphics card will not work correctly, Also, windows makes a backup copy of the drivers and puts them into its driver store for you and keeps putting it back on your system if the driver is deleted. (but it will work until you reboot again because the actual driver is not installed until the reboot)bummer, at this point you would go into control panel, disable the autoinstall of device drivers, uninstall the video driver, reboot, and install with the vendors setup program and reboot. Then enter control panel and re-enable the autoinstall of the drivers again.
