hello ive just reinstalled windows xp on my sony desktop for the first time and am having some trouble. it is with my onboard audio, i cant get any sound out of my motherboard sound. i went on the sony website, downloaded all original drivers, and installed them. but when i installed my audio driver it seemed everything installed correctly, then i reeboot and it was like it didnt even install. i still go to sound, game controller... and no sound or audio is selected or able to be selected. i even go to device manager and cant find the driver i installed. how do i get it on my system?? thanks
