In addition to the other suggestions offered (all excellent), make sure your
excess cables are "barred" not coiled. The coils will act as inductors and
create all kinds of RFI issues. 

Use high quality, shielded cables for your interconnects. If problems still
persist you can build a small "black box" with optoisolators that if used in
conjunction with separate grounding for RF & computer will create complete
physical isolation between the two.

Finally, Jack's remark about line suppression power strips was dead on and
his suggestion about using ferrites should be the first remedy you try after
making sure your cables aren't coiled. It is arguably the single best thing
you can do to minimize interference. Don't scrimp. High quality ferrites are
available from vendors such as Digi-Key for a reasonable price. An excellent
tutorial on ferrite suppression (and what types you'll need) can be found
at:

Good hunting and let us know how it turns out.

Subject: [Dxbase] RFI PROBLEM

Hi All

I have been having windows opeing, closing cause, along with other problems
with RF getting into the computer.  Are those power strips with about 60db
reduction do any good?  Those with the line filters built into the power
strip for the data lines are they any good?  What are the good ones that
work?
