Mac Mini Restarting Multiple times per day
I have a Mac Mini from Sept 2010. Recently upgraded to Mountain Lion and now the restarts due to an issue several times per day. The computer is fine when i am using it, but the issue comes up when i return to wake the monitor by hitting a key or moving the mouse. Sleep is disabled, but the monitor is set to turn off after 10 minutes of inactivity. Sometimes it will be fine left for hours on its own and other times when i come back to the computer, I am met with a gray screen stating the computer had to restart.
Below is the log from the last crash:
