Installing motherboard, cpu and new GPU, Im using old HDs, do I have to reinstall windows xp?
Well, XP is going to detect all of those changes (especially if the MB has onboard NIC). Then XP might complain about it’s validation, so you’ll need to re-authorize it. Not a problem, but may require a phone call to the Windows’ mothership ;). However, if that is happening anyways, I would recommend a new install, just to avoid potential driver issues. Probably not necessary with XP, but over the years I’ve seen strange driver conflicts pop up, that a clean re-install fixed immediately. You don’t need to reformat – just a reinstall of the OS, that will leave things (games/software) on your HD, in case you need to recover something.
