Hello There!

So I just built a new computer last night. I have built several computers in the past, this is the first one that Is really giving me a headache! hah. Here are the parts: 

EVGA 750 GQ 80+ Gold 750W Semi Modular 
EVGA GeForce GTX 1070 FTW 
Intel Core i5 3.2 GHz (Skylake)
EVGA z170 FTW
Ballistix Sport 16GB Kit (RAM 4x4GB)
Samsung 850 PRO (512GB SSD)
CRYORIG H7 49.0 CFM CPU Cooler

So basically, I get these two codes on my mobo during boot. A2 and B2. It is important to note that the computer boots properly to BIOS - and I was even able to install the OS to the system, so after booting - it makes some strange beeps shows those two cards very briefly and then goes to the Windows 10 desktop. Does anyone have any ideas why I am getting these MOBO codes even thought the system seems to be booting properly????

Thanks alot for any advice  

Thanks. I checked those out and I am going to try a number of things. 

Okay so here are the list of things I tried.
 
Stress tested CPU,GPU,PSU,MEM - all passed.
 
reset CMOS - A2.B2
Updated BIOS - A2,B2
took all DIMs out except first slot - A2,B2
tried different DIM in first slot - A2,B2
took SSD out entirely - A2,B2
 
So I have no idea what to do. This code will not go away and I can not pin point why it is happening. The computer works fine and literally all parts passed stress tests. So what the deal?
