Dell Dimension 2400 Drivers

A few months ago i reinstalled windows cuz of a virus and i needed to install my drivers again...i did them all i think but the speaker drivers dident work and ive been without sound for 5-6 months and its getting to me.

i went to dell.com and downloaded them and i needed to restart my computer to get the to work or somthnig and they dont.

What I would do is get the original box for the computer (hopefully you have it) and look at the original settings which should be in the manual.
