So my new Computer was workin' fine until one mornin' I lost power to my desktop due to a blackout during an update and my LAN built into my motherboard stop working. The motherboard claims that it's enabled in the bios but it doesn't show up in my Ubuntu installation nor my XP boot. It's a ASUS P7P55D motherboard. Any info would be helpful. Thanks.

Note: please excuse any grammatical mistakes that don't make any sense because I am typing this out on an iPod.
