[Cube] Cube shuts down & restarts intermittently

[Wade Dunham]

I just sold my Cube on eBay, and the buyer received it today. It
arrived in apparently fine shape, but he reports that after a couple
of minutes, it shuts down & restarts intermittently. Prior to
shipping, it stayed on 24/7. I would only have to shake the mouse to
get rid of the screen saver and start working. Any suggestions would
be appreciated. Thank you.
