Drivers. I had a problem with blue screens from a bug which got into the system and removed all

Question

I had a problem with blue screens from a bug which got into the system and removed all software and cleaned the hard drive ...haver now re loaded and all works fine but the sound and I have none. I therefore need to down load a Mircosoft sound driver for my XP pro or from Matsonic MS 8147c mother board ...I have been looking on Google for two days but can-not find a direct link to the required driver. Are you able to offer any assistance
