PCI Devices Not recognised In Windows XP
 

I have an unusal problem with an NEC PC with an intel 915 chipset, whereby windows cannot detect either the installed PCI cards or the network card (which is integreated with the motherboard), although these are clearly identifiable in the BIOS.

The PC is installed with windows XP pro

The problem originated when windows refused to boot for no apparent reason (it had been working all of the previous day without problem and the ethernet port was connected directly to a router. It shut down without fuss) and I had to boot into the recovery console to fix the MBR. This allowed me access back into windows but resulted in the current problem.

Anything plugged into USB or other ports works without problem

The devices are not shown at all in device manager, as if they are not installed, and all other motherboard functions work without problem (ie PCI express graphics, USB, Firewire, COM ports). Forcing the PC to install drivers for these devices does nothing as this just leaves the device driver with the yellow exclamation mark next to the device in device manager.

The devices in question are a bog standard modem and a TV capture card, both which work flawlessly in another PC.

I have checked the BIOS many times to ensure that the devices are recognised, but still the problem persists. There must be a basic setting I am missing?:dunce:

Is there any glaring issue that I am overlooking as this seems like an easy to solve problem - but apparently not to me:mad:

have you tried search for new hardware in control panel?

if this fails I would try resetting bios to defaults then try bios update
next would be a repair install to see if its just a windows componant gone bad
then the dredded reformat,
My guts worried about the mobo though

Hi Zinglebarb, I have reset the BIOS to default settings and have even upgraded the BIOS to the recommended latest version from the NEC website, without joy.

I have also tried to search for new hardware devices in add new hardware wizard, but again nothing is detected, other than that which is already installed.

I also have misgivings about the motherboard but hopefully this is not the case :Yikes:

try a repair install then or just go for a format,
The initial failure to boot is whats worrying me about the board
