I built a 6 to 10 Amp Corcom powerline filter (available at swaps for a 
few bucks) into a 
duplex outlet box with a short heavy extension cable (16-3 or heavier) 
and plugged only 
my rig into that.  Even better build another and plug the computer and 
monitor into that. 
 Totally eliminated the trash from my computer and monitor, when ferrite 
chokes on the AC 
cables didn't help.
