Been following this thread since day one. I was having these same issues, until i built a new machine, not ONE issue since (same operating system btw Windows 7 Home Edition 64-bit). Now, I know it's not all hardware issues here, but I believe some are being caused by faulty RAM or GPUs, or other hardware problems. This game does call for a ton of GPU usage and could have caused failure where other games are not.

I think people that have not tested, should at least try and troubleshoot their hardware.
