keep tapping F8 when the computer is booting. It will take you to a list with lots of options. You will have the system administrators options, i supect you know this allready. Anyways, you have system restore and cleaning disk options from that menu in XP. If only you knew if u have a virus and its names. When you log in Safe Mode, it has a purpose. You can delete any suspected file that you think might be causing any harm. Safe mode does not allow any files that are important for the computer to function normally to be deleted. And restores them in normal mode. So you can delete your heart out and get rid of the infected files that are supicious. Keep trying. If nothing works, then you must download a win XP Cd, found even on Kazaa. You will download an image, which you can burn on a CD. You can borrow it from a freind if you have just one computer. Then u can reformat without loosing the files, in Xp as I remember. Just trying to save you money. GL.
