MacBook Pro Randomly Shutting Off... Ticking? Can't Boot Up Without Crashing
Hey everyone,
I have a MacBook Pro 2012, and its been an amazing, solid computer up to this point. The computer is running Sierra. As of right now, the computer will randomly shut off completely. When I try to boot it up, it goes back to black screen without even reaching the apple logo loading screen. If I leave it plugged in, it will do this multiple times on its own, as well as produce an electronic ticking sound from the top right corner of the base. If I wait a while (Idk exactly how long) it will successfully boot up and I can log in. I have tried some basic stuff but nothings worked so far... please help me. I am very desperate, as I have thousands of dollars worth of software on the computer.

This is a video of whats happening. Right off the bat its doing the restart and shuts down... Near the end of the video at 0:58 or so you can hear the ticking.
