Ok so about 6 months ago i reformatted my computer, and after it was all said and done i lost my audio in the process, well i tried countless times to fix it and every time i go to install realtek AC 97 it pops up during installation saying “the software you are installing has not passed the windows logo testing to verify its compatibility with the windows XP” i have read many forums and i see this is a frequent problem to some folks. so if anyone can please help me i would greatly appreciate it, this is an on going problem that has my head scratching forever.
