im not giving the gfx back mate, im in loveRight, still testing parts... my friend took the gfx card to try on his system and found that it was okay, nothing wrong with it.
I'm ordering my new case next week, getting the Antec 1200 and on thursday, hopefully I'll have all my parts back. We'll put everything back in and see what the outcome is.
I think it's down to 2 parts (CPU & Mem), unless we're missing something.

(that means the graphics card is fine, so that aint a problem)
on a side note, it surely cant be the ram/cpu as you've tested it with memtest fine
