I had this problem largely resolved by replacing the power supply in the

This is a biggie,I've seen a large variance in PSU filtering...
Some cheaper PSU's don't even fit the filtering components to the
PCB's,they jumper over the common-mode chokes,and leave the caps off the
board!

Some PSU's have 2 common mode chokes in series,and alot of filtering...
It depends.

Another tip,If you can fit one,use one of the IEC sockets with the
built-in filtering can on the back on everything in your house that uses
an IEC socket,all the SMPS's in everything now days are nasty.

Ferrite every cable on your PC,at both ends of the cables.
(okay,maybe just one ferrite on the mouse and keyboard,or else it might
get annoying.)

Basically filter the hell out of everything-go overboard with it.
PC's are *horribly* noisy beasts to tame..
