I purchased a program called "Driver Detective" a while back and i used it because my Windows was corrupted and so i had to reinstall it, in the process of doing so i wiped my hard drive of everything including drivers, so i got driver detective and downloaded all my drivers back. since then my windows had a virus so i recovered everything again but this time driver detective could not find the audio driver download usually it would appear as "PCI device" and have a little save icon to download it, but now there is no icon and im unable to download it.
