What do you have for Windows version and what do you have for a video card, motherboard and cpu?
Have you tried updating the driver for the video card?
Windows 7 Home Pemium 64 bit
Video Card: Integrated 1600MB Intel® HD 3000 &
512MB AMD RadeonTM HD6470M
Motherboard: Dell Laptop?
CPU: Intel® CoreTM i3 2310M (2.1GHz/3MB cache)
I think the problem started with updating the video card, BIOs, etc.
