The square waves from the M/b are murder; the sum of all harmonics as I 
recall, meaning it's liberal in resonance.

My guess is the signal's getting to the TV antenna. Try moving the 
computer away from the antenna wire; not it's probably in a wall.

Alternatively, if you can, disconnect the run from the Computer at the TV 
end.

Someone suggested changing clock speed; changing bus speed's also a 
possibility - it may be resonating with the 50/60/66/75/83/100/133 Mhz bus.
