When I start my Mac Pro by pressing the power button the fans kick in and it sound like it's about to start for a second, then it immediately switches itself off. This happens time after time every morning. After unplugging everything from the back and plugging it all back in again I can often get it to start up, eventually, then it's usually fine for the rest of the day. Next morning, same problem. It's very disconcerting.

This problem has only started to happen fairly recently and I'm pretty sure the warranty has expired. Can anybody help?

    Sounds like you might need a SMC reset.

    I've been having the same problem for 5 months now and it seems to be getting worse!

    Did have a spell when it was fine for over 3 weeks then one evening powered up, got as far as chime and gray screen/apple logo then clicked off. Since then it's hit and miss as to how far through the start up process it gets.

    Fed up with it!

    Unplugging seems to help as does moving but only for a short time.
    Have taken it in and had it looked at to no avail, suggestions being to try a new power supply or logic board. Going to start getting expensive!

    Seen similar faults but rare!??
    Anyone??

    What else have you tried?

    it sounds like an issue I was having with my Mac Pro earlier this year, as it would turn off and not turn back on (which I believe a black out in the neighborhood was the culprit). I eventually took it in to the Genius Bar where they fixed it. It was the Logic Board and PSU that they replaced. Everything (in terms of powering on) was fixed after that point, although I do have a new issue. lol.

    Buy a good solid 1500VA UPS and protect your equipment.

    Have the same problem, push the start button, runs from 2 to 60 seconds, shuts down. Tried all the fixes suggested on this site, no joy. Took to the repair shop (twice) and they could not duplicate the problem after several days each time, so brought it home and worked o.k. for a couple of weeks and then started doing the same thing. The third time I took it to the shop,we plugged it in while I was there and it would not start. They ordered a power supply and I should have it back tomorrow. Glad I have applecare.

    Why not, try running your Apple Hardware Test . It's not perfect, but may flag something.

    Will definitely let you know if this cures the problem.
