hey
i came across this post...
i had the exact same problems! I have an OCZ Modstream 520W PSU.. and realized the problem was a badly plugged PCIe power connector on the PSUs end...
after connecting.. no more crashes!!
it just sounded weird to me that no "power disfunction" was brought up by either the OS or the BIOS on the VGA... but hey: its working perfectly now!!
The weird part was that even though FPS games were crashing, i could play for instance PES4 without the power connector correctly plugged :S weird huh? :S oh well... bahh
take care,
