text: windows xp? if my computer is messed up bad and i install windows xp will it fix it?    if so how do i install windows xp on my computer? it depends on what is wrong with the computer.  you would be best off doing a clean install which means formatting your hard drive and then installing xp.  you should save whatever data you want first if you are able, and it would also be of aid to know what all you have installed in your computer.
