Jenson,
Thank you for the response.
I'm confident it's not the discrete GPU because the BSOD log specifically points out the Intel graphics driver. The log hasn't reported any errors with the nvidia drivers.
As I said in the original post, I've done a thorough memtest86. The ram came back error free after 5 complete passes. I'm not sure what you're talking about with erasing the gold teeth terminal, however I do know the ram is error free.
The CPU certainly has sufficient thermal paste. I installed it only a week or two ago from a brand new retail box. I've also verified the CPU is in a very safe temperature range, so do not believe the thermal paste or cooling is an issue.
I'm using a 660w SeaSonic PSU. They are one of the revered names in quality power supplies. I'm using the i5-4760 (100w), Nvidia GTX 760 (170w), Samsung SSD (>1w), leaving more than plenty of headroom. I agree that trying a working PSU is a good troubleshooting step, but I believe the issue has been resolved...
Downgrading to the .3345 driver, I haven't noticed any crashes. With the 3379 driver it was crashing every hour or two of use.
