Dead LAN Ports?

Recently there was a thunderstorm, and lightning struck a nearby powerpole. As a result, our modem died, and so did the GIGABYTE switch.
I replaced the modem, and confirmed it working with some laptops, both wirelessly and by cable.

But now, my stationary computer won't even detect that there's a cable in. There is one unknown SM Bus-controller showing up in device management.
Does this indicate that my built-in LAN port is dead? It's a Marvell Yukon something something. If so, what can I do to fix it?

The second LAN port also has problems, I can only get "Local Acess" only no matter what I do. It has been like this for a while, though.

What are my alternatives here guys?

Motherboard is a Asus Rampage Formula.

Does the Ethernet port light come on when you plug the cable in? If not, then your port is fucked. It'll light up if you have drivers for it or not, unless of course the light is shot, which is very rare.
