I WANT TO REMOVE MICROSOFT VISTA AND REP...

To be able to do a change from vista to xp you have to do a clean install of the XP...that is you have to restart your PC and BOOT with your XP CD.First you need to have all your driver.If you go on searching for drivers according to your Laptop Model you'll get confused or maybe not find them.Install this software [EVEREST] first from here http://www.softpedia.com/progDownload/Everest-Home-Edition-Download-16369.html and when you run it you'll find the make and model of your hardware.The important ones are AUDIO,VGA [Graphics] and the LAN [that makes half of your worries go away].Download the drivers for the three from their specific sites or search them on Google it makes a lot more easier. For the installation of XP,this site will give you an Idea http://www.winsupersite.com/showcase/windowsxp_sg_clean.asp read each and every step and I suggest if you are doing it for the first time you use another computer so that you can get help if you want to.you can also find this youtube link helpful http://www.youtube.com/watch?v=JlnddZ7w5J8 and http://www.youtube.com/watch?v=EufVizUCSOI&feature=related I hope it helped.
