Computers work through layered, dynamic processes which mean ANY playback will be electrically different. In fact, replaying the same file a second time is more likely to yield a difference because the file is likely to be cached entirely in memory the second time. I say likely because dynamic management means the cache is reclaimed piecemeal by other processes as time goes on... None of this is useful from an audio point of view in terms of understanding what is "better or worse" noise! The audio designer should concentrate on rejecting EMI and RFI noise from wherever it comes - whether computer circuits or a fridge. (Which gives me an idea: the audiophile fridge!)
