Closed PC power-off Tags: CPUs Power Last response: November 15, 2010 5:46 PM in CPUs Share Nads63 October 31, 2010 8:24:55 PM Why does a PC power itself off while a user is working, for no apparent reason? There is no given indication of the intention to power off. Just powers off as if there were a houshold power failure.
