I had / have a similar problem, but it was / is related to plugging
in a usb device.  It appears to be a static electricity issue,
although I never get a spark.  However, it completely goes away if
I remember to ground the end of the usb cable I'm about to plug in
(touch to my finger) and ground the port on the computer (touch my
finger) before plugging the one into the other.  Try consciously
touching a metal ground point on the box before you do anything
else.  Drove me crazy, still does when I forget and the whole thing
freezes up.  And yeah, it should all be well grounded, but
apparently something isn't.
