I was wondering if it is possible for some one to play a joke with you by putting essentially summoning circles on your dvd for your OS and cause the sound to go up and down and really deep bass like every one was demons or something. Plus all the videos were messed up like boxes around the top of there heads and smiles were really messed up. The computer ran really slow. I just got windows 7 home premium and it no longer does that. One good thing about it was oblivion was a whole lot more frightening.
