Hey whats up I was wondering if it was possible to have a a virus which makes your computer freeze. Because my computer has always worked well, but all of a sudden something happens and now it always freezes. And sometimes it even freezes at start. Is there a way that I can stop this? What causes a freeze and how can I fix it.

Im pretty sure you guys are going to tell me to reformat, but is there any other alternative options? I would say my computer is pretty secure, Im running Windows XP, Pro edition.

Please any help would be greatly appreciated.
