      The last several Dell Desktops I've ordered would do this. Not for the duration you specify though.

      First order of business - Open it,.. Pull everything out (not the CPU) and put it all back. If this was newly shipped, it is possible that the Memory and etc could just need to be re-seated.

      If this does not resolve it,.. it's likely either something more serious.. Maybe either with the CPU or the MOBO itself.

      i tried to pull out everything excluding CPU but the same thing happen,
      Note : there is no beeps,
      this computer has 5 years old

        Okay - What about indicator lights? The 780 should have status lights of 1-4. Are there any ones blinking?

        Likely that your PSU has crashed.. there is enough voltage to cycle the fans but little else.

            PSU = Power Supply Unit

              Yes - as SAM mentioned PSU Power Supply.

              The power button does have a green LED - but the numbers 1-4 should be amber. , and they actually maybe on the back of the unit. They are a POST - Power on Self Test - code...

                Various solutions to remove booting errors:

                • Verify the Computer Finishes Initial Power-Up (POST)

                • Unplug All External Devices

                • Check for Specific Error Messages

                • Reset the BIOS to Default Values

                • Run a Computer Diagnostic

                • Check Dell Optiplex 780 Manual for more solutions.

                  Can you try swapping the RAM DIMMs, or removing one.

                  Also try:

                  Disconnect it from the wall outlet, press the power button for 30 seconds for 2-3 times, connect it to power and power it on again.

                    @gjacobse In the past I have had issues with the 780 and 7010 series where the power button board causes this issue. Replacing the PSU did not work so found out the issue on the power button just in case the PSU does not work for you.

                      Funny how a necro-post (almost seems like a bot-post) by @cucezo has brought new life to this thread.

                        Funny how both posts by that account are totally bot-like...

                        edit: both their posts have links to "guideusermanual.com". not suspicious at all.

                            As mentioned, check the power button itself. Still have 780's here many times the button sticks and will cause this symptom.

                              What ever came of this? Was it the PSU?

                                Apparently this got abandoned.
