You need a new CD Key for XP. That key is tied to the system it was installed on.

Question though; why are you installing XP instead of 7?

You need either an XP install disk and a valid activation key, or the restore partition that existed on the HDD when you bought it, or the DVDs you were supposed to create not long after you bought it.

But XP? Just don't.
XP has less than 3 months of safe life left. April 8, it goes completely off support. No security patches, no upgrades...nada

Not only that, if your going that far back, you probably can't find drivers for your various components. Many people forget that new products may not have drivers for your components. Check before you jump.
