Motherboard will not boot.

[Smoblikat]

So I just got a new motherboard and it wont work now. I installed windows on it no problem and then when I went to add all the real stuff to it (RAID cards, RAM cooler, USB 3.0, new GFX) it wouldnt boot. It gives me error code B2 when either of my RAID cards are plugged in , so I took them out. It gives me error D7 when my KB/M arent plugged in, so I keep those plugged in. And now its giving me error A2, so I took out 3 sticks of RAM and left in one and it still wont display image. I have tried 3 graphics cards and all 3 work in other systems. I have no idea what the problem is but im about to just RMA it. Please help me.

EDIT - Suppose the name would help:
ASRock Z77 Extreme4

Did you update the BIOS after you installed Windows?

In case anyone else has any input, these are the debug codes he is referring to:

0xA2 = IDE Detect
0xB2 = Legacy Option ROM Initialization
0xD7 = No Console Input Devices are found

No I didnt, I installed it just because I cant install it on my RAID card and then proceeded to setup my computer the way it should be. I sent it in for RMA anyway, it had a broken USB3 hub so I figured it was faulty.

Install latest BIOS, thats what I always say there is a reason for it, and its not beta unless it says so.

This started happening, or its been like this since you build rig ?

RAID cards sux, mobo onboard RAID is much more civil I think.
