my window xp is running very slow
Could be one of 50 things with how much info you provided. Maybe 54 things.
Need to list your system specs, what you did to try to fix this, if you get any error messages, any other issues aside from it being slow, is it slow in only certain places or slow in anything you do (that means opening programs, opening files, moving around the hard drive, internet, etc..., don't just say EVERYTHING is slow, that helps no-one).
