My Psu on my old computer crapped out and I just ordered new parts for a nice new q6600. The only thing I have a problem with is im gonna reuse my old seagate 120 gig hdd. It has alot of info on it games etc and its running windows xp pro. How would I go about getting it to run on my new system? Would I have to reinstall windows again? I wouldnt mind formatting it but theres info and programs I need?
