Have you installed the latest driver for your graphics card from the Nvidia driver download page. This would be first port of call. Download the latest drivers, install them and see what happens.

OK.. I'll try to download the file from the link you gave me.. later I'll install it,I'm only using the driver bundled with my video card when I bought it.. tnx for your help sir! Godbless...
