Well....all of my windows software expertise flew out the window this weekend. Wife decided she wants better speed for computer so not to let a good FSX upgrade opportunity go to waste I jumped in with both feet. Idea was to put system in my computer into her case (her's is a smaller footprint, semi portable case) reattach her drive and voila...instant upgrade for her. Put in new motherboard and cpu in my case, reattach drive and move forward. Both machines are running separate copies of XP home. What a disaster. Neither drive would actually load windows... hers or mine. After fiddling with it all weekend long, I put her machine back the way it was, attached a newly formated drive to my upgraded hardware, installed xp and called it done for the weekend. So....my goal for her machine at least, is to NOT reformat her drive since all her programs, files, and bookmarks, etc I would very much like to leave alone. If there's no other choice, I'll format and start again, but I'd welcome other ideas.
