If the PC emits RF, it could just get into your guitar cable or pickups - and it would make perfect sense that with the PC off you don't hear it.
You could make a quick test leaving the PC on and all in the same position, but disconnected to the 11r - and play the latter as a standalone unit. Try also have someone moving the mouse (is it wirless) or so.
Maybe i wasnt clear on my issue, but as soon as the pc is off and i play through the 11r, the noise goes away. When the pc is working hard (cpu fan works more) it increases the noise. To me, its obvious that the problem is coming from the pc. Is how to get rid of it the problem :)
