I just recently purchased a new motherboard, AMD cpu, and computer case. However I came to the realization that there is more than just installing the parts into my new case and hitting the power button. I completely spaced the fact that i would need to do some downloads/updating on the software side of things....but...where and what do i start with???? I would like to use the same hard drive from my old pc, but if thats going to be too much of a hassle im willing to get a new hard drive and OS.
