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.
