Finally finished a new build but am experiencing a weird issue.
When I power on it shuts off almost immediately and 3 seconds later comes on again by itself and boots fine.
I've changed and removed all the hardware down to the motherboard, cooler and power supply.
I changed the power supply and it does the same thing. I'm told, that some motherboards do this as normal behaviour?
I've made a quick video: https://vid.me/DyAv
Board is ASRock Extreme7+, i7-6700k and corsair 750w psu
Any ideas?
