When you say "I lost my onboard LAN". What exactly do you mean?
*That you cant see it on device manager? or That you don't have connectivity?
Can you see any lights on the network card port?
Have you done any recent changes that might have caused the issue?
What operating system do you have? What service pack?
What is the version of your BIOS.
