A new install of Windows XP Home is giving us some issues. We suspect that the root cause may be an error in the listing of hardware devices:
Control Panel / System / Hardware / Device Manager

Under Processor, the processor appears twice, and under System Devices, Motherboard Resources also appears twice.

I have attempted to remove ALL the duplicated items and reboot the computer, but when it comes back, the devices are still listed twice.

There is no yellow question mark beside the items in question, indicating that the OS seems to think everything is OK, and if I examine the properties, everything says it is working properly.

I know this is wrong, and I suspect this is causing other errors (mostly in games), so I would like to get this corrected. However, I don't have any ideas of what else I can try.

Appreciate any and all ideas....
TIA,

Did you also re-install the motherboard-drivers?
They came on a CD, or if lost, you can find them on the manufacturer's website.

Reinstalled the chipset and sound drivers from the motherboard CD. The LAN drivers that were installed with XP seemed to be working fine.

I had a suggestion from another source that I may have a hyperthreaded CPU which would account for the double entry. Does that make any sense to you? It doesn't to me, but what do I know?

CPU is an Intel 3.2GHz. I don't recall any other details without going through old sales receipts to see if there's more info there.

In point of fact Intel processors with hyper threading technology do in fact so up in device manager as 2 CPU's and the motherboard resources also appears twice on such intel chipsets. so this is NOT the source of your problems. although you could probably CREATE problems trying to remove these entries.

It's a bit soon to say for sure, but it looks like the problems I was having were not the device manager duplicates -- which have now been explained to my satisfaction -- but due to the fact that I neglected to obtain XP version of the motherboard drivers. It just never occured to me that the motherboard drivers would be OS specific, so I installed from a CD I had made with the Win98SE versions when I first downloaded the latest drivers for the motherboard.

Live and learn!

Thanks for everyone's assistance.
