ive been trying to fix my friend's computer for a while now and im totally stumped. he first had this problem after upgrading to SP2; the sound went away. uninstalled SP2, still no sound. its the realtek 97 audio and the drivers for that are installed but the problem is with the "plug and play software device enumerator" which gets a yellow "!" in the device manager. i uninstalled it planning to reinstall it but it just disappeared (oops lol) its a 2002 compaq presario (no model # that i could find) with an athlon xp 2600+ 512mb RAM and a geforce 5200 (pretty much all from my old computer lol) any ideas guys?
