The principal offender with respect to noise from computer systems is the monitor, This is because of two factors. First, the deflection circuits tend to operate in frequency ranges (under 40 kHz) that are below many other systems and they have lots of harmonics- Second, those deflection circuits tend to be high-power. The answer to the probiem is to place shielding around the circuits and a common mode choke in the signal line.
