device manager unknown Problem Device

July 10, 2011 at 20:16:06
Specs: Windows XP, amd athlon 64x2 dual core 4200+
device Manager (XP) shows 'problem device' at PCI Slot 17 (PCI bus 1, device 0, function 1) and if i delete it wants to reinstall. I don't know what it is or what drivers it wants. I have a Gigabyte 8400GS installed as display adapter at PCI Slot 17 (PCI bus 1, device 0, function 0) if that is significant. Any advice for me please?

Is that what it says, "problem device"? And I could be wrong, but I kind of doubt it's "PCI Slot 17".

The device is listed in Device Manager under 'Other Devices' as PCI Device, with a yellow question mark and exclamation mark against it, and has in Properties as Device Status 'The drivers for this device are not installed. (Code 28)' . The "PCI Slot 17 (PCI bus 1, device 0, function 1)" was copied and pasted from the Properties/General/Location field for the device as was the similar line for the video card.

More: I found a link in this forum to www.zhangduo.com/udi.html 'unknown device identifier' (excellent) which has told me my device is an nvidia device with pnpid VEN_10DE&DEV_0BE3&SUBSYS_34CD1458&REV_A1.
My geforce8400gs is already installed as VEN_10DE&DEV_10C3&SUBSYS_34CD1458&REV_A2 so maybe the videocard wants another driver???

I have been unable to find another driver including on the nvidia site so i am still in a quandary with this unknown device. Everything seems to work ok but i do not give my videocard much of a workout so that means little. And XP still detects it as a 'new device' and wants to load driviers which of course it is unable to find. Any help would be appreciated. At present i have it marked as 'do not use' and 'dont ask again' in respect of installing drivers, so its a bit of a head-in-the-sand approach at present.

Have you disabled the on-board video adapter since fitting the PCI video adapter?
If not, the unknown device could be the on-board one, but If it is I can't understand why it would detect is an "unknown device". Still, anything's possible.

You need to disable the on-board video in the BIOS settings. Windows won't detect it at all then.

Hi Pip, thanks for the thought, but this motherboard is an ASRock 939dual-sata2 which does not have an on-board video adapter.

SOLVED! FWIW, on a usenet group about nvidia cards i found a post where someone had had problems with their card until they installed XP's SP3. Although the problem was different, i had not installed sp3 after a recent xp re-install, so i installed sp3, and on reboot xp identified the 'unknown device' as a 'NVidia High Definition Audio Device'. Loaded the drivers and all is now well. No more 'problem devices' . Have no idea what the HD audio does but whatever it is the PC and i are both happy again.
Thanks to the people who tried to assist me.
