How do I reset my Dell 4700 to when I first got it?

Are you planning to sell your computer to someone else after you have recover it to factory settings? If yes, I will need to add some extra security precautions to the normal recovery procedure.

Also, do you have the discs that came with your computer? Do any of these discs say something like “Windows XP Reinstallation Disc” or ” System Recovery”?

Thanks!
