Had a desktop computer with bizarre pointer behavior.  The pointer would
jiggle at a frantic rate and would keep returning to the same place - off
center - on the screen.  The computer was utterly unmanageable.  After
heroic efforts I got a reasonably clean shutdown.

Dual boot, Mint and W8.

Being a newbie at the moment I brought it to a repair shop who told me that
Linux had attacked the Windows partition.  I paid them for their
"diagnosis" and called another shop who were similarly baffled, but asked
one crucial question.  "Are there any other USB devices attached normally?"
 I started laughing, because I remembered that I had - but had not been
using - a touchscreen.  The connector must have been loose, producing a
spurious signal, causing the manic pointer.

I was considerably happier paying the second fellow.
