If mobo is mother board I have no disk for it . Came with the computer The audio card is the one that came with the computer and has not been messed with for 3 yrs. anyway I have no disk for the audio card. I did not change or install anything having to do with audio. all I installed was XP. I don't understand what you are saying. Other than changing to xp this computer has no add on devices except my HP all in one printer. Other wise it is a very plain generic no frills computer. The only discs I have are xp ,hp, quest dsl, I don't have games or other stuff added. Just what came with xp. Please enlighten me
