One of the best overall driver sites I've ever found. Pacos Drivers
http://pacosdrivers.com/

At least one link I followed for S3 video drivers required a login name & password. By leaving the name & password fields blank and continuing you may be provided with a guest login which in the case of the S3 site was "archive" for both the name and password. It was however the only link out of many I followed that required a login so it may be a unique instance.

A conclusion is the place where you got tired of thinking.
