    My Mac has been shutting off by itself with no warning. Sometimes it takes me 5-6 times to get it up and running.

    sounds like it is over heating. try downloading a temp program and check your temp.

    Do the fans race like mad before it happens? I had issues with my G5. First the power supply and then pretty much everything else went. Had it overhauled like twice and then I wrote to Steve Jobs and they gave me a new MacPro.

    Nope, it's not the temp. What else could it be? I thought it was the power strip, but now have it plugged directly into the wall.

    And no, no racing fan noise.

    Did you try resetting the SMU? Little button on the motherboard next to the ram slots.

    We opened it up, couldn't find any buttons. Vacuumed it out, put it back together. I went to pick up the kids, and when I got back the darn thing was off again!

    Is it a liquid cooled one? Any small puddles anywhere maybe forming?

    It's tiny and black. Look around the ram, it's there.
