2 nforce2 boards, same problem. i have an nf7 and nf7s-v2 board, and both have come down with the ill-fated code 10. device will NOT start for some odd reason. It could probably be a bios problem but i really have no idea. If you go into the device manager and look at network connections you will see a yellow circle with an exclamantion point and if you click properties it will say device is installed but will not work properly CODE 10. I can't figure it out for the life of me. HELP!
