New build harrassment BSOD

recently bought a new PC, it suffered a couple of BSOD then the graphics card stopped working. I asked for a replacement, got it installed today and after 3 hours another BSOD, I dont know the source of the problem and the people I bought the PC are useless. I'm attaching the minidump, if anyone has any ideas whats causing the problems please tell. I spend £600 on this PC and so far in two weeks I've only gotten about 5 hours of gaming out of it.

Did you test your RAM

thanks it looks graphics related from all the ATI bumf on the page, I'll run the memtest now anyway.

BC TDR116 is also caused by defective RAM or PSU :)

do you think this could be caused by the power supply overheating?

PSU rarely overheats so I don't think its the cause

cheers for that, I'll run some tests for now.
