Picked up my Pro this weekend. There is an odd cyclical buzzing sound that's happening non stop (attached). Game or attract mode, it's happening. Changing the volume level does not change the volume of the noise. It's coming from all three speakers. When it first boots up it's a little fuzzy like a hard drive sound, but quickly turns into this after a couple minutes of warming up. In my quiet room it's noticeable while standing at the machine. It's -like- the sound of interference from a blinking light, but I can't seem to tie it to anything.

Please advise!
