Network controller stopped working when an expansion board was added to the computer.
Cause Solution
The network controller requires drivers. Verify that the drivers were not accidentally deleted when the
drivers for a new expansion board were installed.
The expansion board installed is a network card (NIC) and
conflicts with the embedded NIC.
Under the Computer Setup Advanced menu, change the resource
settings for the board.
Network controller stops working without apparent cause.
Cause Solution
The files containing the network drivers are corrupted. Reinstall the network drivers using the Recovery Disc Set in
Windows 7 or Windows recovery tools in Windows 8.
If necessary, download the softpaq from the web (from a
different computer).
The cable is not securely connected. Ensure that the cable is securely attached to the network
connector and that the other end of the cable is securely attached
to the correct device.
The network controller is defective. Contact an authorized service provider.

sequence to boot from another source.
