Perhaps you can play a bit of detective work. Usually, the most electrical hash comes from the monitor, or the cable from the video card out to the monitor. 

Once the computer is booted, pull this connector off at the computer end and see if that helps.

Ditto for the mouse, keyboard. One at a time. 

I've had sound card/ audio cables become antennas and radiate stuff. Usually, changing cables to something with more shielding or tying the shield to chassis would help. 

It may be a fan motor causing your (electrical) noise - if you can unplug those briefly to see if the noise changes. They're cheap DC motors. 

I've had better luck with 15" flat screens near mics than CRTs, if you can swing that. Plus it gives more desk room, and less heat load.
