I need to update my video card, because i cant play some games.?

My video card says 8800 GTS on the side if that helps.

What i need is a website link that lets you update my video card for free.



PS: I think I have a cracked version of windows 7, it says:

Windows 7

Built 7600

This copy of windows is not genuine|||google 8800 GTS drivers then download the video/graphic drivers|||Its not a matter of updating your card its getting a new better one.
