Reformatted my computer and installed Windows XP on it. Apparently somewhere my computer lost my sound drivers, and now when I try to install the ones from the Dell Website is doesn't work, it says its installed but when I go to audio it says there are no devices even thou I have my speakers hooked up. When I try to double click on the sigmatec audio program it says that it's curropted or not installed right and windows can not open it. I have a Dell Precision Desktop 390, with Sigmatec Audio Card. Help, I must have my music.
