I'm currently having trouble with my setup!
I'm using the following specs

Intel Core i7-5820K - Boxed
EVGA SuperNOVA 750 G2
Corsair Hydro Series H110i GT
Asrock X99E-ITX/ac
Geil Super Luce - DDR4 2400Mhz CL14 Kit - 32GB
Sapphire Radeon R9 390 - Nitro OC Backplate
Samsung 950 Pro - 256GB

It's not giving me any BIOS screen, it's my first time working with an mITX motherboard.. did i forget something?
Once i boot up the pc, everything starts to work.. Lights go on fans do their job full blast.. then they go to a much slower speed.
I'm kind of a newb when it comes to building, However im sure i can work my way around!
Anyone knows any way i can test what the cause of this problem is?
(checked GPU with my own Desktop GPU.. same result)
Thank you!
