What must I do to get rid of the conflict between the wireless ethernet card and the wired ethernet NIC card in my mother's computer?

Whenever it turns on it displays an error about a plug and play configuration error (you can get past it by hitting F1)

Also I installed the drivers for the ethernet card and both the wireless and ethernet card were displaying in the hardware list correctly for a few days. But now only the wireless card remains and the ethernet card has disappeared.

Yesterday it was saying it found new hardware (for the ethernet card) and it couldn't find the drivers.

So obviously there is a conflict between these two cards.

I've had this conflict before in an older computer and resolved it by removing the ethernet card (I didn't need both cards).

I was running Windows XP before when I experienced this issue, and my mother is running Windows XP now as these two cards conflict again.

Thanks in advance! I suppose I could just remove the ethernet NIC card from her computer as well but I'm betting there has to be a way where both the wireless and ethernet NIC card can be in the system at the same time without a conflict. Although I'm not totally sure.....that's why I'm posting here

Thanks again.

Are they both PCI add-on cards? You probably need to start shuffling the cards in the different PCI slots until its happy. If one is build-in and the other is add-on card....try it in another slot. I have a system with a wireless card and 2 wired NIC's....all PCI...all happy together.

Sorry for the late response, Yahoo doesn't deliver the topic reply notifications for some reason.....just browsing aroud.

I've sence taken the wired NIC out because I don't use it. I'm not sure but I might have had the cards back to back in the PCI slots, I can't remember....maybe that was infact the issue. Thanks!

Why not use the NIC on the motherboard?

All you need to get that working is the nforce driver. Gotta love nvidia's unified driver stuff.
