[RFI] computer shut down

[W9RPM]

Hi, I recently started having a problem on 30 meters with one computer 
with Multiple Monitors jumping everything around on different screens, 
and another computer shutting down. I have a couple of other computers 
in the shack that are not affected. I did install a new 30 meter beam, 
and the problem seems to have started after that. SWR is fine. This is 
running 200W.

Any ideas of where to start?
