Sounds like a possible hardware failure. Power the system on and access your BIOS (press F2). Locate and disable your on-board ethernet adapter. Save and try restarting the system normally.

Also, your boot settings seem to be trying to boot from the network, this could indicate a HDD failure as well. While in your BIOS, check those settings (boot order/devices).

Please share the results. Good luck!
