I had a virus hit my friends computer that disabled his anti-virus even after reinstalling it. When I went to run the program it said it wasnt there and it wasnt. Main prgram was gone. I know its a new computer but one bad trip on the net can ruin it. If it was store bought call them up and ask. If its self built (which I hope it is) you can try a reformat and reinstall as a last option. Other than the virus I'm out of ideas.
