I recently had my tower changed and when I got it back the ethernet port which is built into the motherboard is not working. It has a yellow light instead of green. It does not show up in network connections. I have tried to uninstall it from device manager but device manager doesn't let me uninstall it. I have tried to update the drivers but it doesn't help. Everything was working fine before the tower was changed. I even reinstalled XP (not a complete reformat but an upgrade install) and it didn't help either. I am about to give up on it and just use a USB adapter. I would appreciate any suggestions.
