Driver up date questions

Hi, I have a GeForce 6800 NX grahics card and I have recently have had some issues with my graphics.  Once I load a game the screen freezez and a whole bunch of little blue rectangles appear all over the screen.  Is this a driver problem?  If so what driver update do I need?

www.nvidia.com - if you are updating the drivers, they are all generic dependent on the family of card and OS you are using.
e.g. Graphics card -  Geforce and TNT2 - XP

What specifications does the game command?
Does your system meet them?
Is this a new problem or a recent development?

The game's requirments are far below my system and this is a new problem.

Have you installed anything new recently?

Try system restore to an earlier time.

I have just wiped my computer clean and a short time after that it started to act up.  But I haven't installed recently before it happened.  It is really weird though.  I have been played these games before and nothing unusual happened.  Also intresting is that I can play the new call of duty demo with no problem.  I just updated the driver for my graphics card too.

Windows & directX uptodate?

I bet you installed default Windows drivers for your videocard.
