Hi,
I'm 90% sure my new Maximus VII Gene has an hardware issue but I give it another try.
If you have one, maybe with a i7 4790K like me, does yours boot in a kind of 2-steps process?
- push the button
- fans start, light on the Corsair H100i cooler turn on for 1-2 seconds
- fans stop, light off for 1-2 seconds
- fans start again, light on the cooler turn on again and finally boot
I also did a short video of this 2-step boot process (don't pay attention to the sound, forgot TV in background):

Thanks a lot
