Yawgy is correct .... the drivers may not have had much to do with the real problem. However if you want to try new drivers nvidia.com would probably be the first stop. If you want a whole lot of driver options then try this page:

Be aware that TNT video cards are not generally supported on the newer drivers. I think they stopped supporting them after the 50 series of drivers but could be wrong.
