So I just installed Windows 7 on a pretty old pc in my house because it was really shitty and needed to be re-formatted anyway (it had xp before) and everything is working perfectly except I get no sound because it won't recognize the sound card drivers.

Now I really really don't want to have to go download a new copy of xp and reinstall that cause I've spent way too long on this computer, and the sound is the only issue.

The computer is a Dell Dimension 8300. The specs are Intel(R) Pentium 4 CPU 3.00 GHz, 1.25GB RAM, and a 120 Gig HDD. I installed Windows 7 Ultimate RC Build 7100.

In the Device Manager it says there is no driver for the Multimedia Audio Controller

This is the sound card driver I tried to use but it won't work, maybe cause it's made for xp? It's called R58182.exe, I got it from the dell website under driver support.

If anyone can help I will love you forever.
