I had a switching supply on my LAN router that was giving me fits.  So I'd 
smack it on the desk top (pretty hard I might add) a few times and the noise 
would go away (or at least detune it for a while ; ).  Sure as heck it would 
return at the most inopportune moment, so I'd smack it up side the head a few 
more times.  Replacing it with a linear supply seems to have solved the problem 
forever.  But it occurs to me, do you have some device hooked to a UPS?  Or the 
UPS itself may be a problem.  With the interference so loud, it has to be close 
by.
