A lot of BSODs while gaming. Different every time.

I have been getting BSODs every couple days.

SYSTEM_SERVICE_EXCEPTION
BAD_POOL_HEADER
NTFS_FILE_SYSTEM
MEMORY_MANAGMENT
PAGE_FAULT_IN_NONPAGED_AREA
KMODE_EXCEPTION_NOT_HANDLED
CRITICAL_OBJECT_TERMINATION

I used to have x2 Asus 5770 GPUs crossfired.
I figured it was the cards considering I got ATISYS errors.
I just bought a XFX 6870 yesterday and still getting BSODs.

It seems like something different every time.
I have been trying to figure out what is causing the BSODs but I just can't narrow it down and I'm totally losing it.
Lately I have just been letting it go but now this is really getting on my nerves.
Someone please assist me.
I greatly appreciate the help.
I'll upload a .zip of my speccy report and bsod files.

The dumps indicates a hardware issue.

In order to eradicate the BSOD, please do the following
