I need Computer help!

[Onimusha12]

This might be a good time to tell you that I am clueless and inept at searching for things on the net.

I need the following drivers for Windows XP

USB 2.0 Wireless Network Adapter

Multimedia Audio Controller

Universal Serial Bus (USB) Controller

Ethernet Controller

SM Bus Controller

I downloaded a driver detective to find them for me but it requires $30 to use so I thought I'd come here for help from my peers. Any advice (preferably helpful) would be greatly appreciated.
