TweetI'd just wipe it out and start from scratch(format)...put a windows system in that you like... install anti-virus and anti-spyware
My mom has my old computer and I have no idea what the heck she has done to the thing, but I am going over tomorrow night to see if I can't clean it up.....She has so much crap on there and never defrags or scan disks so the thing is always freezing and does other odd things and who knows how many viruses are on it since she let the anti-virus lapse..argghh!
Good luck with the "new" computer fo yours!
