Well I've been working on this problem since March and am finally giving up and asking for some help. I did a clean install of Windows 8 x64 after using Windows 7 Ultimate x64 with no problems for many years on this machine. After install things work just fine except I have one device that is labeled as unkown. In Device Manager right click > Properties > Details Tab I get this Information:
and a google search has so far turned up nothing.
Also my computer was an HP Pavilion a1350n (same mobo, cpu, dvd) just upgraded RAM, added a 5.25" and 3.5" floppy and a couple USB 3.0 ports and newer nVidia Card but the system worked just fine under 7. Now my computer has an integrated Realtek AC97 audio card that I just can not get to show up at all in device manager in Windows 8 and an installation of the drivers does absolutely nothing to help. Any help would be appreciated.
