    New PC takes multiple tries to power on

    I'm a IT Pro, but I wanted some more opinions on this one.

    PC is custom built and less than 6 month old. The specs don't really matter just the usual system (750W PS, Quad Core Intel, 8GB DDR3 RAM, ATX Case). The PC has started developing the symptom of not turning on the first time you push the power button. Its progressively gotten worse to where now it takes 3min+ of trying the power button before it will power on.

    Things I've tried:
    - Took case apart, inspected power button and wires; they were good
    - Checked motherboard connector/pin, was good
    - Checked all voltages being outputted, they were good (+12, +5)
    - Tried a different wall outlet, and power cord


    When the system is on, it works fine. I think I may have seen this in the past long long ago, and it was a bad PS. In the end it eventually just doesn't turn on.

    Anyone have any input?

    When I hit my power button, my computer turns on for a few seconds, turns off, then turns on and gets going.
    It was somewhat bothersome at first, but it's done it since the day I put it together.
    There's nothing actually wrong, and it works just fine.

    That's what I get for buying an open box motherboard I guess

    I have a 2700k i7, do you have something similar?

    37.5 MPG, AC on, cruising at 80.
    30.0 MPG, AC on, aggressively driving around 90.
    27.5 MPG, no AC, cruising at 90 with occasional gridlock. 40 degrees Fahrenheit

      Does it power on when you just jump the pins for the power button? Other wise i'd probably just replace the power supply.

          Sounds like you are on the right track. My first guess would have been faulty power button/wiring, then loose connection at the board, and finally power supply.

          There are of course other possibilities if it isn't the power supply. Other problems could be the memory isn't reading properly preventing the cpu from getting proper start up voltage, the motherboard could be bad, or if by some chance your motherboard is refurbished or open box special you may need to reset your bios.

          Hope you get it worked out. Good luck.

            Yep, this is what I would try as well. Just short the pins with a jumper of some sort (paper clip, alligator clips, pin jumper, whatever) and see if it works as expected. You don't need to keep it shorted, in fact you shouldn't; just do it momentarily and remove the jumper.

            Another easy way to test: if your case has a reset switch, try connecting that one up instead and see if it works as expected.

            If nothing above helps, I would troubleshoot the PSU first, then the motherboard next.

              good idea using the reset button! And I never tried jumping the power pins, I may try that also. But if these fail, I think I"m going to go with the PS replacement.

                  You said you inspected the Power button, how through was this inspection? Did you take it apart? Have you tried a different power button? It could be a poor connection in the power button.

                    This seems to be the simplest approach.
                    The power button isn't really associated with any software, is it? It's just a simple on/off switch (at least when the computer is off, anyway.) That simplifies things. it's not a software-related issue. Simply an electrical issue. That means you have 3 possible options: the switch, the wires, and the power supply.

                    If you're an IT pro, I assume you have plenty of spare parts sitting around (I'm not a pro, and I have at least half a dozen computers floating around my house!) I'd try another switch, and if the result is the same, look to the power supply. I've seen screwy power supplies cause all sorts of weird symptoms in the past!

                      Took front bezel off and took power switch apart, inspected wires connections and pin.
                      But as mentioned prior I'm going to use the reset button as the power button and see if I get the same results. <- Great idea which I never thought of doing.
