Ron,

You might try grounding the pc to the station ground.   If it's a 
desktop computer, one of the 4 screws that hold the power supply is a 
good grounding point.  Otherwise any good connection to the pc's chassis.

You might want to try and determine just where the noise is coming from. 
  Try unplugging various things and see what makes the noise go away: 
keyboard, mouse, monitor, USB cables or other cables to peripherals. 
Even wall warts for all the computer connected junk.   Once you find the 
offender, you can  try ferrites  to tame it.

I wound up going to a wireless keyboard years ago.   The one that had 
come with a new pc was noisy.  No noise with the wireless and one less 
cable to deal with.
