Random Windows 7 BSOD BCCode 1e

Hello seven forums I need some help from an issue I have been having. I have a Dell Optiplex 755 that has randomly been giving BSODs. The error usually pops up randomly, usually when I step away from the computer and come back to find the computer has reset itself and all windows and browsers that were open are closed and a message that "Windows has recovered from an unexpected shutdown.

This is the error I receive:
Problem signature:
