I have read two similair but did not quite answer the question I am looking for. My motherboard in my Hp a1130n went out. I purchased a new motherboard but it is an atx so i purchased a new case as well. I was just going to put everything from the no longer working computer into the new case that has a new motherboard. Then I got enough money to build a new machine. The hard drive from the Hp has all my music,videos.etc on it. I need to keep those. I have another computer i use for gaming. I would like to make that my new computer for music and every. I then wanted to sell the hp component computer to someone else. I want to put the music hardrive in my old gaming computer and the old gaming computer into my new gaming computer. I am basically trying to swap hard drives. I have read that this can happen and i have read that this cant happen. I do not want to purchase a new copy of windows and reformat or copy or ghost. I would if possible I would like just swap hardrives. A thread by savage something said that it worked for him. The post Can i? said it can not work. I need to know if it can or if it can not. First thread sorry if confusing.
