Your motherboard is not presenting a double startup but a very normal behavior on systems that support Intel® AMT such as yours, as this feature initializes at the time of boot up. After Intel® AMT initializes, the system boots into the Operating System.
When you see the system shut down, it is that Intel® AMT has finished initializing so booting into the Operating System is the next step the motherboard will do.
We recommend you making sure you have the latest BIOS version of your motherboard, as well as the latest Intel® ME Management Engine Driver for a proper recognition of the Intel® AMT controller.

Thank you for you fast answer.
I installed Intel Management Engine Components but there are now just two more processes running on my system and I dont see any advantage in that nor a solution for my double start-up. Fact is: My system goes on, stay on for some seconds, turn off and then on again. If that's normal or not: It's bad for my built-in components and I dont want that! So please could you tell what I need to do to turn that off?
Regards and thanks again.
