Ethernet controller driver for IPEX

Hi there, Can anyone help? I am looking for drivers for the following: Ethernet controller, video controller, USB controller and USB device. The computer in question is an IPEX Convergence desktop. I have tried locating the drivers using Driverguide toolkit but driverguide cannot locate them. I am a premium member with driver guide so its a bit frustrating that it cannot loacte the drivers. If anyone can help or can suggest any paths to follow, it would be much appreciated. Cheers, Dave.
