Bryon,
I do not recall the details of how your computer is connected to your audio system, but assuming it is via wires, then I would most likely attribute the difference to a change in the computer generated noise domain resulting from a configuration change to the computer.
I'd be very interested to know if a difference was heard changing drives if the computer is isolated from the stereo using a wireless connection. I would predict not, but it would not be the first time I was wrong if so.
