It depends on what you mean by "CLEAN". If the cd you have from the manufacturer is a "Restore CD", chances are it's the XP install cd. When you run the install, it should format the harddrive, meaning completley erase every file and partition you have. If you want to do a complete wipe w/ a fresh re-install, that's the way to go.
I've heard of some XP disks that DON'T format automatically, but give you a choice whether you want to. I've never experienced one of those myself, so i don't know what it edits or keeps.
Remember, before you reformat and re-install, save any files you need to keep on a floppy, cd-rom, or flash drive.
