This site often used for "Backporting" newer computers to XP now has loads and loads of Windows 7 drivers
you can integrate into your install disk so you don't need to "hunt down" drivers or get scammed into PAYING via SNEAKWARE when you use something like driver
All the stuff here is 100% free and its an excellent site.
I used it a lot very successfully when I was "De-Vista-ing" computers a few years ago --original VISTA on hardware available at the time ran HORRIBLY.
Anyway loads of Windows 7 stuff now on the site. News | DriverPacks.net
