Are you overclocking your video card at all? The error is exactly as it says. The video driver crashed for some reason, but luckily nvidia drivers are built to recover/reset when this happens rather than hanging the entire system.
I have found this driver version to be very helpful for my nvidia graphic issues.
Download it from here. http://laptopvideo2go.com/nvidia/255...15_winxp64.exe
That is the 64bit version I assume you need by looking at your OS you listed.
Please install and try this then reply back if it helped your problem.
