Have you followed the Repair Install (aka in-Place Upgrade) procedure after
installing the new MB?
During the initial installation XP configured itself to suit the hardware in
order to provide a more stable system. Because of this a major change in
hardware
can cause the kind of boot problems you are experiencing.
**** If you have a XP installation CD ****
Any important files should always be backed up in advance of hardware
changes.
Many users, myself included, prefer to do a full clean install after major
hardware changes as you describe.
The alternative, and equally valid option, is the repair install (also known
as an In-Place Upgrade).
See following Knowledge Base article for details. Pay careful attention to
the possible loss of data links in the MS article.
How to Perform an In-Place Upgrade (Reinstallation) of Windows XP

After doing this you may need to re-activate your installation of XP. If it
has been more than 120 days since you last re-activated you should be able
to activate over the internet, otherwise it will require a short phonecall.
After the repair install you will need to re-install any XP service packs
and updates, but you will not need to re-install any applications.
Hope that helps
