What do you assign to Mordor?

[Galadriel55]

I assign computers that do crazy things behind your back.

My computer decided that it will have lots of fun erasing all the memmory and all the programs (even those basic ones like Word), and instead of showing a window for the internet it now covers the whole screen, without the blue border or anything, even covering the Start button... I'm practically banging my head against the wall trying to get it to work properly...and not succeeding, obviously...
