Not at all, a power suply won't effect anything at all if you replace it, its just like replacing batteries, except nothing on the computer will reset. The only thing that will make you loose your stuff is replacing the harddrive, however if you had to do that it seems it still runs, so you can clone it using a program by synamatec called ghost i believe it is, i know the process is called ghosting, I have the program here somwhere.
There's a free program called Drive Image XML (or DIX - hahahaha!) that will do the same job.
Oh cool, for once I didn't get this one on the low down, school was giving away copies as they got macs and didn't need all the copies and lisences anymore. I will deff try and look for this program you speak of, good to have a couple, because sometimes computers just reject stuff, dam things.
Did you mean replacing a power supply?
Exactly my thoughts, but he might be pointing out that replacing say hardrive b will not effect any programs installed on harddrive a, providing HDD a has windows (or other OS) installed on it, as an example, me removing my music HDD won't effect windows running, or any of my other programs (also installed on a sperate HDD)
Yeah that one... LOL
