• Answer:

  You need to do a clean windows install. That means you need to reinstall your copy of windows. If you have a computer such as a dell or hp ( any mainstream company ) then call them up and usually they give you another installation disc for free or for a low price. If you are a computer expert and have another computer that has the same version of xp on it then follow this tutorial http://www.howtohaven.com/system/createwindowssetupdisk.shtml If not, im sure the people from the company you bought your computer from will try to help
