BSOD Lots of odd issues with this PC HELP PLZ

OK I have been building PC's from Newegg and various local store for my family members, friends and Co-Workers. I am not a Programmer or anything of that caliber but i built at least 20 PCs over the past year alone, mostly gamer rigs. But this one, which so happens to be mine, keeps giving me alot of issues.

I built it originaly about a month ago, and after a few days got some file corruption messages and BSODs. Running MEMTEST 86+ it narrowed out the ram pretty fast 100,000+ errors in like 10 minutes of starting. Various timings changed the error count but was by far from STABLE. I RMA'd the RAM to Gskill. Recieve that about a week ago.

I since did a clean install with Windows 7 64Bit.
Mainboard: ASUS M4A79XTD EVO
RAM: G-Skill F3-12800CL9D-4GBRL 1600 MHz Ripjaw series. (2x2Gb)
CPU: AMD Phenom II x4 955BE
GPU: XFX GTX 260BE
PSU: 650 watt HEC-XpowerPRO

It passed a few hours of Memtest (3-4) so i began the fresh install. Everything worked fine for about a day.
Second Day I was playing Modern Warfare 2 game, and the game screen went Grey it rebooted after about minute or so and the CPU internal Speaker did the Pre-Post beeping to indicate no graphic card installed or what not.
I reset it manually with the front panel power switch and it boot fine. Windows report a Hardware failure, with the GPU. So i went and found a newer driver, i was using 195.6 or something and there was a 196.21 driver that just came out. I installed that.
Next day.. It crashed just loading GTAIV, Hardware issue it says, agian. but different error message. In fact just prior to the failure i got an on screen popup about DirectX failed to do something, then Win 7 popup said something i may need to run in windows basic theme disabling Aero to increase performance of my resources being low. (Yeah like my video car doesn't have the HP to run on Win 7.)

I went into the controll panel and removed everything that had the Nvidia logo on it(via program remover) and then rebooted. I let windows find the drivers for my video card and install them.

PC worked fine 2-3 days, I thought i was out of the BSOD era...... Wrong

Tonight about 2 hours ago i was just surfing the Net piecing the next rig together for a new build for my son. Was reading a review, not opening anything at all. BSOD

SO i am at a loss now. I figured it might have something to do with running stable with 1600MHz ram, as it seems to be a common issue with these CPU according to googling things, so i just set it to default / auto in the bios which defaults it to 1333 MHz. I only bought the ram due to a sale, if its ram related and 1333 works, so be it, but is it? I think i zipped the .dmp files right so here they are, please help if ya can.

the motherboard has the most recent BIOS, the video card is acutlly older than the cpu mobo and ram. its about 10 months old. was in my old PC that I pieced out for a friend. SO i am not thinking the Video card is bad it served me very well.
