Years ago, a guy with a background in RF engineering told me that from an RF 
radiation standpoint, the PCI bus was horribly designed, so that's probably 
another of the many sources.  The main one is still the CPU, and since this 
didn't happen until after your upgrade, the CPU/mobo are your main culprits.  
CPUs do put out lots of RF interference.  Back in the old days, there was a 
program (probably several, for various platforms) that could play music over 
your radio if you put it close to your TRS-80.  It caused the RF output of 
the CPU to vary and played music.  The owner of my neighborhood Radio Shack 
had it on a TRS-80 there.
