Hello;
Allow me to welcome you to the HP forums!
Sorry, but with a 15-year old PC, presuming it has the original hard drive, it's likely that the filesystem has become corrupted over time, and if that has affected the original Recovery partition, the HP reset function simply will not work anymore.
An added problem is that HP stopped carrying XP Recovery Media long ago, so you won't be able to order recovery disks from HP.
Since HP no longer provides Recovery Media for your model, a couple of other sites you should check are: http://www.computersurgeons.com/ and http://www.restoredisks.com/
If they don't carry it, an additional problem you're going to face is that no one sells XP anymore, so you're not likely to find any place that will sell a new copy to you.
