Win Xp change mboard and cpu?

[JGM]

I want to change my motherboard and cpu and keep my old case and
peripherals....Any advice about re-activation of my OS and my MS Office I
want to keep everything else the same and the same HardDrive. My IP address
will be the same?

Thanks JGM

IP address has absolutely nothing to do with your subject.
Will you have to reactivate? hmmm most likely yes.
Do it online if you can.
