   Well, kinda.   Just make a repetitive sound and check the power drain in the   
   PC to see if it induces a repetitive current draw.   In other words,   
   measure correlation over a long term.   Other than a microphonic   
   component, it's not likely this test will find a correlation there.   
      
   That assumes that there's no store-and-forward internal element, and that   
   PC operational 'noise' isn't dominant (over the long term, like hours, noise   
   will average to zero).
