Alright...it's crazy that so many poeple are having this problem. I have the remnants of what used to be an HP Pavilion mx70. It's my grandparents computer and before I arrived they had some problems and...it looks to me like someone charged them to take out the old board and put it in a new box. The audio is built into the board and I did try the steps suggested to the other HP owner but when I got to the end of the install for the ADI 188x well it told me that "the drivers weren't found" and that I should reboot and try again..so I did...and got the same message. Any help?
