The suggestion was - try another keyboard/moust - as I said I think it
becomes a hardware issue, perhaps I should have said inside the box, try
memtest and see if it is flaky, check your on board temp, lm-sensors,
try anything, but be prepared to buy a new box.
I don't think that changing the mouse and keyboard will impact anything.
It does have to be tested, or you won't know.
