My 2009 mac mini randomly reboots. It is running OS X El Capitan 10.11.6
Hi everyone, a few weeks ago my mac mini started randomly rebooting. sometimes it automatically loads to the sign in screen and works just fine. However, most of times it either freezes on a gray screen with an apple logo, or it reboots multiple times and never gets to the sign in screen, or it freezes in a gray screen with a big "ø" symbol with some text over it saying basically that the computer experienced a problem.
The following images are of the report that appears when the computer starts again.
I don’t understand anything of what it says.
Any help is greatly appreciated.
