I am running Precise on an AMD Phenom II X2 3Gig, 4Gig Ram, with a ViewSonic 1080P HD monitor.

Thunderstorms in the area caused me to shut down the system, and when I rebooted this morning, the dekstop background and icons sizes had all changed, and my lan card would only hook up with a 100Mbit connection, as opposed to the 1Gbit it has since I built it.

I cna change the background back, but have no idea what changed that changed the size of the icons, and no idea where to start with getting the Gbit lan card back to Gigs instead of Megs.

Also, what could have caused all of this to change, and where do I go to get it back to where I was?

Your help will be greatly appreciated.
