Onboard nic help

I lost the wired connection on one of my motherboards and I am trying to determine if the onboard nic has failed?


Have tested:

cable

router

tested whole set up with laptop-connection fine

drivers

reinstalled os(win7)

checked device manager

tried uninstalling driver and let windows install it on reboot

reset ipconfig/all

updated bios

also tried a linux live cd and no connection(wired)


Not sure what else to try except RMA the thing back. Any suggestions? Thanks

You covered everything I would have tried. I'd say go ahead and RMA it

sadly that is what i thought. Thanks
