It looks like there's still a problem with the graphics
drivers (0x3B) possibly due to a damaged or corrupt system file (win32k). I'd run a system file checker scan from an elevated command prompt (option two.) If problems are found, run the scan 3 times and reboot the computer after each scan. See if the problem is resolved.
SFC /SCANNOW Command - System File Checker
If not, I'd next try to roll back the Nvidia
driver to a previous stable version. I'd try using the Nvidia "Beta and Older Drivers" link to find a driver from maybe 6 months to a year ago. Install that driver and check for problems. If no problems are noted, try upgrading to the next newest driver. Keep checking until (a) you've installed the latest non-Beta driver or, (b) you find a driver that causes issues, in which case go back to the previous driver.

You may also want to read through this Nvidia forum thread about how to uninstall/install Nvidia drivers. Apparently, things have changed.
