Sorry for my bad English, I speak French.

I have a problem with my new custom PC:
i7-4790k
Asus Z97-E
Avexir 2x4gb
EVGA 750w bronze
Bitfenix Shadow
Seagate Barracuda 1tb

When I first boot my pc, it works.
Then I shutdown: it works
Then I boot my pc again: The fans spin, the LEDs are on, but the screen is black. If I press and hold the power button to shut it down, it doesn't work. I need to shutdown the powersupply at the back of the case.
Then I press the power button again and it boots normally.

I need to do this everytime.
What's the problem?

Thanks!
 
Solution
I would replug all cables/reseat all the components except the cpu.

Be sure the hdd is plugged into the lowest number sata port. If it already is, try the next one...
