    Hi,
    My MacPro 2010 12 core tower out of nowhere shut itself off and then would not turn on.
    I unplugged it from the wall and tried and it did not work. Suddenly out of nowhere it turn itself on and then it held power for couple minutes and turn it off by itself again.
    I called AppleCare and they said to try to reset pushing the control/option/shift keys and power button at the same time and releasing it at the same time. That made the MP turn back on but it held the power for 1 minute. The Apple care guy said to wait couple hours and try again.
    If that doesn't work to take to repairs.

    Does anybody had this issue before and knows what causes and how to fix it?
    I really appreciate any feedback.
    Regards
