Unknown pci device in device mgr - cannot get rid of it

If anyone has a clue what this is, I’d sure like to find out:

Had a problem develop suddenly (no known cause) with onboard sound on an HP6735, 15 gig HDD, close to 190-something MB ram, running Win Me. Device mgr showed a conflict with the WDM audio, and in addition, showed conflict with an unknown pci device. Deleted the sound to let Win recover chipset sound, didn’t work; restored device driver from system restore disk, still didn’t work; formatted and restored the whole drive image, still didn’t work; disabled the sound in the bios, and installed a sound card, sound now working fine. Throughout this whole time, at each step, the unknown device continued to show as a conflict.

There are 3 pci expansion slots in this machine, they are all now occupied and fully functional and accounted for by Windows (sound, modem, ethernet) yet device mgr is still showing an unknown pci device with a conflict. It’s clearly a hardware problem that has survived even a clean re-install of the os. What could be causing this? Does anyone have any sugestions what this may be? never had this one before!

thanks! maureen

 

Did you install the motherboard drivers first thing?
Under Sound Video and Game Controllers, is there a Wave Device for Voice Modem?
