Lost all Audio

Hello, I was hoping someone could give me some insight as to what may have happened to my Logitec speakers. My Compaq recently crashed, so I reinstalled everything but now my speakers aren't working and I can't even put the volume icon in my system tray or the desktop because the tab isn't there in the Ctrl Panel under sounds, multimedia, etc. I am running Windows 98. There are two satellite speakers, one subwoofer and a remote. Everything is hooked up correctly and I tried to install/update the driver but my computer couldn't find any software to install the hardware with. I also when into "Multimedia" in the Ctrl Panel and it said there are no Audio, Mixer, Line Input and MIDI devices installed. The computer was given to me and I didn't recieve much software with it and there isn't any Logitech disks. Are the speakers uncompatible now? Plus, I also lost CeQuadrant JustBurn (no disk for that either).
Thanks.

 

Compaq Presario? Which Model?

 

My Presario Internet PC-1999 (I believe)
