New Computer Please help BSOD

[Syntax1985]

Hi all,
Just a quick explanation :

I recently built my pc, brand new everything, all worked fine except i was getting random artifacts on my screen, even right after booting on the windows desktop.

I put this down to a faulty card, and replaced the new card with an older 560se ( the new one being a 7950 )

It worked great, so i RMA'd my 7950 and received a new one today.

after uninstalling nvidea drivers & installing new ati drivers, everything worked fine, i was playing bf3 on ultra and getting a solid 60 fps ~ 70fps, but my game crashed after about 15 mins of game time.

So i launched Far cry 3, and got a BSOD right as i loaded a new game. i did get BSOD on the other card i RMA'd.

SO either im the most unlucky guy in the world and ive been given 2 naff cards, or there's something else wrong in my system....

as instructed in the how to thread ive uploaded the data from the SF diag tool, Thank you in advance to anyone taking the time to help me

Update : While browsing the forums just now, my screen flickered black a few times, ive never experienced that before,
Seems its getting worse...

And another update :

I ran memtest a few days ago ( just seen some people ask about it ), it came back 100% fine with 0 errors
