There's no such thing as "Windows XP". Windows XP is a general term. Microsoft has....Windows XP Editions

Home Edition

Professional Edition

Media Center Edition

Tablet PC Edition

Professional x64 Edition

Which one "exactly" are you refering to???

I assume you've chosen to do an "Upgrade (recommended)" installation, rather than a clean installation?

If so, I'd suggest doing a "Clean" installation, reformatting your drive and starting afresh with XP Pro. This would delete any data files you might have, music, pics etc, so copy them to another drive or partition first.

Make sure you've got your driver disk handy to reinstall them once the new installation has completed.
