Hey, I'm helping my gf upgrade her computer from a P3 450 or something to a P4 system. The only thing that's staying in the computer from its present state are the drives. I've had problems doing such changes in the past where I pretty much need to reinstall the OS. Is there anyway to avoid all that? The thing is, in W2k, I can usually get by with doing a repair, and I'm not a huge XP person, but I've seen my roommate unable to do repairs with XP, where you MUST have a ASR disk or reinstall, no easy repairing. Countdown of about just under 2 days til the upgrade. Would like feedback as soon as possible.
