Nervous system manipulation by electromagnetic fields from monitors

I suspect it's actually an audio frequency that's causing such effects. Some SMPS emit a rather annoying, and quite loud, squealing sound in normal use --- which some people find annoying, but I wouldn't be surprised if some people find it absolutely unbearable, even if it's not audible; e.g. the typical horizontal frequency of broadcast TV is around 16KHz, and many people can't hear it but still perceive that there is "something" when subjected to that sound.

I once saw a TV documentary several years ago that noted how wind farms were affecting people from resonation, with affected individuals getting headaches and crying fits.

These wind farms were absolutely massive (tens of feet wide), and installed on gigantic concrete bases. This served as a natural amplifier for the vibrations generated by the gearbox and motor.

None of this was audible, but it is still technically frequency-related.

As an aside, I've heard my computers make noises on a couple of occasions, and the only thing it's caused in my case is concern that the computer was okay :) - on one occasion I discovered if I held my head right that I could hear the whine of a CRT flyback transformer, and on another occasion I discovered (again if I held my head right) that if I ran a certain graphic demo program (the Xtacy linux screensaver) on a certain graphics card (a Matrix G450), a whine could be heard emanating from the PC tower. Someone I shared this with (I think on here) reckoned that this was due to overdriven power MOSFETs.
