I think this is the key here. The game runs fine until certain strains are placed on your graphics. This is where you should center your trouble-shooting efforts IMHO. Have you checked your in-game graphics settings or the graphics setting in your GPU control panel? Maybe something as simple as toning down the "Particle Density" setting could be the answer here. Also, monitor your system temperature (if you can) while certain loads are placed on your GPU. It could be that your GPU is overheating. Hopefully you don't have a jumble of wires hanging down and interfering w/airflow. If so, tape them together and out of the way.
Sorry, wish I could offer a sure-fire fix.;)
