  Are these PS/2, or AT/serial?  Any chance two PS/2 devices are reversed?

  I would definitely try a different keyboard.

  Most motherboards should be grounded at three points:

1.  The ground lines of the power-supply connector.

2.  The contact between the mounting brackets of expansion cards and
the case.

3.  Screws through one or more plated-through holes.

  Grounding *all* -- or even just many! -- of the exposed contacts on
the underside of the board to one another is a very Bad Idea.

  Testing the mobo outside the case isn't great, because you have to
rely on #1 above only.  the surface the board rests on should be non-
conductive and anti-static.
