Shift key creates "|"

[Kay]

I inherited a used computer, and have an intermittent
problem with the left shift key. If held down, it acts the
same as holding down the pipe "|" key. It's repeatable,
but does not happen every time, and does not do this with
the right shift key. I was wondering if there may be a
Windows configuration function that may have a created a
macro or something similar for this functionality. Bottom
line, if it is software, I want to turn it off!
