Exact same problem as before, with the same driver unfortunately.

Would it help if I just reinstall windows from scratch as my install is 3 yrs old? I just need a stable system.

I gotten a few video driver recovery error messages. New Nvida driver out so I updated to 331.65

You could try installing the program again.

Turned the computer off last night but didn't wait for it to shutdown. This morning it was still on, so I turned the monitor back on and moved the mouse around but nothing came up on the screen. After hitting reset to reboot I checked and there was a new dump file.

I would suggest rolling back to a few earlier WHQL versions of your nVidia graphics card driver, since it seems to be having issues with handling power related IRPs.

I uninstall the driver from device manager and had to reboot as the driver software wasn't recognizing the graphics card after the uninstall. After a reboot I told Win7 not to search for a driver and install 320.49 which is 2 versions earlier. 331.65->327.23->320.49. That is the same driver I had when I started the thread. I let you know how it goes.

Okay, thanks for the update :)

I was just thinking, the problems with the Adobe driver could have been caused by the nVidia driver's interaction.

Update:
3 weeks ago I switch from Firefox v25 to Chrome. Since then my system has been much more stable. I had one freeze early on but no BSOD for nearly 3 weeks. The research I've seem to suggest something about the hardware acceleration setting in that version of Firefox as the source of the issues.
I upgraded my computer with 2 new data HDD (not system)to increase my storage 2 days ago. Today I got a BSOD but no dump file was created. Here is a picture of the BSOD.
