What is a good strategy for finding the right video and audio drivers?

1) Download all possible drivers for your computer.
2) Install each one, until you find one that works.
3) If you couldn't find one that works, try the drivers bundled with the operating system. For example, for Cyrix MediaGX, there is no audio drivers made for Windows 2000, so use "Creative Sound Blaster 16 Plug and Play (WDM)" instead.
