Need Motherboard drivers (by 2 users)

I did a clean install of XP pro on my HP Pavillion 522n. I found the video drivers for the motherboard and chipsets. I am lacking sound and cant find the drivers for sound. The sound is AC'97 ADI191A. I've tried installing the drivers for this sound i downloaded from a website and when its almost done, it reboots my computer and sound is still nowhere to be found. So I'm looking for the motherboard drivers and trying that route. If anyone can be of any assistance it would be greatly appreciated. HP is of no help and neither is the ASUS website. I even called Tech Support and they cant help me. Someone out there has to have a solution. Thanks in advance
