I actually tried that by downloading the drivers and putting them on a flash drive to install onto my PC before I got my wireless working... it gave me an error and never installed.
When I go down to the sound part - there is a little red X over it and I can't do anything with it. Also, when I go to device manager and try to update, I still have no sound. I think i'm about ready to just give up and re-install XP on this old junk, lol.
