My guess is that your antenna is coax-fed and is more than just a few
feet from your computer.

We must keep in mind that the RFI generated by the switching power
supplies in a computer system enters the ham receiver via the receiver's
antenna input.  Those using well-matched coax-fed antennas are probably
bothered very little by this type of RFI.  But those whose antennas come
into an antenna tuner located in the shack are probably more cognizant of
the problem.
