Xp Blue Screen After Change Hardware

[BigG]

Thanks all for the quick response.

I basically replaced the old Pentium motherboard with a P-II mother board; vedio card also chagend from a old PCI one to a AGP one. Other controllers are just moved over.

If I do re-install, can I install on top of the current XP (just like the old Win9x days), and keep all software installed on the HD? Or I have to re-install all software again (tons of them)?

Thanks again.
