I want to do a complete clean of my laptop. That means taking it back to the original factory settings and getting rid of every file and application on there. A complete and total clean. It is operating on Windows XP and I have the original authentic code but I do not have any boot discs. - where can I get that info from? I am happy to download the info and make new set up discs myself (as appose to purchasing them) but I don't know where to get them from. Can you help?
