I'm going to attempt to build my first computer and I need a little help doing so. I've got an emachines that I'm going to swipe the cpu, ram and hard drive from to place in the new pc. Question: I have winxp on my current rig, what steps do I need to take before I can exchange the hard drive? Do I need to merely reformat the drive and then shutdown and place it in the new machine, then load up winxp on the new rig? Any help is appreciatted.
