Custom Built PC Problems

I am really at the end of my patientnce now i don't have a clue what is wrong with my PC

Specifications

MOBO : 970 PRO 3 ASUS
CARD : 7870 ASUS 2GB
CPU : 8320 AMD AM3+
PSU : XFX 850W MODULAR 80 PLUS
HARD DRIVE: HITACHI 2TB 3GB/PS
RAM: CORSAIR VENGANCE 2X4GB

I am getting BSOD constantly

This is what i have tried.

Flashed my bios to the latest version to support the 8320 CPU.

Then i thought it was potentially a hard drive problem i erased this by runnig CHKDSK, and other tools which gave me no errors, also replaced it with another ard drive for testing purposes and this did not work either.

I then got told to run memtest86 so i pulled my one ram stick out leaving the one in running it over night to get 12 passes no errors so now im at the end of my patience

What on earth could be causing this have recieved numerous message on bsod here is one

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000001a (0x0000000000000031, 0xfffffa8008eea9d0, 0xfffff88002c1a000, 0xfffff8a0085f791f). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 122312-45427-01.

Any help would be highly appreciated.
