Okay so here is an update:
I spoke with Overclockers, and we started by eliminating things. Hard drive etc. Got to the graphics card and I took it out, and it was still crashing... so not the graphics card. Power unit is brand new can't imagine its that. Then disaster strikes... the pc isn't even turning on! And it's just crashing on load all that kind of stuff.
I then went into the BIOS when I could finally get there and turned the internal fans from Normal up to turbo and it SEEMS to be working okay, and I am not crashing in game. Of course I need to test this for a longer to see what happens, we will see...
Failing this... I will have to return for repair 1 day in
Sad I know, but if this doesn't work I have no idea what's causing the crashes. I also stuck a big fan up the backside of the stack to push even more clean cool air through it. It's got like 6 fans in it already though ¬_¬
Update again soon.
