Multiple BSODS

Hi all, since about a month ago I've been getting seemingly random BSOD's, When the problem started there were a few things that were constant, i would get stuttering in games every 1-2 seconds for a second, non-stop, and i would get audio crackle while watching videos and opening programs at the same time, and of course the blue screens. The crackle and stuttering are gone the system runs perfectly fine performance wise, just the crashes.

I was getting errors like IRQL_NOT_LESS_OR_EQUAL, PFN_LIST_CORRUPT, DRIVER_VERIFIER_DMA_VIOLATION, SYSTEM_SERVICE_EXCEPTION, SPECIAL_POOL_DETETCED_MEMORY_CORRUPTION. And others..yeah alot.

I've since replaced my ram as i thought that was the cause, i went about 2 weeks without a problem now its back again. I have also upgraded my PSU recently as some people on another forum thought that was the problem. The DMP files included are the only ones I have, the BSOD's dont seem to always create them.

Current Specs:
GPU : Nvidia GeForce GTX 670
Processor: AMD Phenom(tm) II X4 955 Processor (4 CPUs), ~3.2GHz
Motherboard : Gigabyte GA-970A-D3
Ram : G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
Operating System: Windows 7 Home Premium 64-bit

Any help is much appreciated i will include the DMP files that i have.

EDIT: Last 2 hours i have had no blue screen while google chrome has been closed.
