Photoshop :: CS6 Locks Up Computer Using Lighting Effects?

I have been able to reproduce this lock up consistently using the Lighting Effects, and I can also get it to lock up while using the Lasso tool, and also setting guides, but those are less consistant. I have tried to switch the advanced graphics options around too. It is currently on normal though. I currently have the GeForce Drivers v. 320.14 installed, which at the time of this post is the most recent stable build. I have even gone so far as to try every GeForce driver from 295.73 to 320.14 with no luch at resolution. Some of the drivers let me get a little further with the lighting effects, but still eventually lock up the computer... Currently I have had to uninstall Photoshop and then re-install it just to get PDF export to work right, but even after updating to the newest version of PS, I still get these lockups.
 
Here are the rest of my specs just in case.
