Also the speakers will still affect it even if they are turned off, cos they have bloody big magnets in them. However, if your wifes iMac is affected it sounds more like pickup from the wiring.
Im not sure about US wiring, but in the UK, they change the standards every year, and if you are in a house over 10yrs old the wiring maybe of a bad/old standard. One thing has just occured to me, I was in a Comms room once where the cables went all the way around the room under the floor, the last spur being near to the entry point. This caused a rather nice magnetic field effect in the room. Moving to another room cured the issue, but, in your case if one room has this wiring chances are they all will. Just a thought.
