Thanks for the quick reply and the link. The pc was custom built, so I don't know. I have no idea about the ethernet cards either. I'm a novice when it comes to computers, sorry. Having run some software I found out it has a platinix motherboard (I'm not sure if that helps any). It also said it has a sound blaster sound card and according to the article in the link you provided, they can cause conflicts. I checked the sound and vid cards in device manager and they seem to be working fine though. I was just trying to install some newer usb drivers and the instructions said I needed to remove any unknown devices before I install them for it to work right.
