Hi:
First, I am not all that familiar with BIOS or hardware issues so please forgive my obvious ignorance. I have a DFI DK 790FXB-M3H5 MB with an apparently dead onboard lan. The system worked flawlessly for several months. Just recently my nephew tried to install a TV tuner card and killed the lan doing it. When he tried to install the card, he did not disconnect the power, he just shut it down. According to him when he tried to insert the card into a slot it "slightly" touched my X-FI sound card causing the small LED on the motherboard to turn off for a brief instant. When the system was booted after this, there was no lan available. Everything else seems to be working fine. (so far/knock on wood) Using a Hiren's CD I ran numerous diagnostic tests outside of windows and every test fails to see the onboard NIC. Under Windows, Everest shows an IP of 127.0.0.1 and an all zero MAC address.
In my bios the Onboard Lan setting is enabled. I have cleared the CMOS, and reflashed the BIOS all to no avail. I obtained the NIC's MAC address from my router's table. But at this point I have no idea what else to do. One of the resources I had used before, csd.dficlub.com forums is no longer available.
I have also emailed DFI but unfortunately no reply has been received and frankly I don't expect much help from them.
So, can you possibly tell me whether my problem is likely an actual hardware problem, or a corrupt piece of firmware? Also, is there anything else I can do to better diagnose the issue?
Thanks for any and all advice!
