What is making my Mac Pro shutdown?

I installed a new SSD and upgraded the memory and now the computer shuts down for no reason. I'm running 10.9.5

Any help will be greatly appreciated.

Thanks

Mac Pro, OS X Mavericks (10.9.2)

Clean Install of El Capitan or Later on a Clean Disk


  1. Restart the computer. Immediately after the chime hold down the Command-Option-R keys until a globe appears.
  2. The Utility Menu will appear in from 5-20 minutes. Be patient.
  3. Select Disk Utility and click on the Continue button.
  4. When Disk Utility loads select the drive (usually, the out-dented entry) from the side list.
  5. Click on the Erase tab in Disk Utility's main window. A panel will drop down.
  6. Set the partition scheme to GUID.
  7. Set the Format type to Mac OS Extended (Journaled.)
  8. Click on the Apply button, then click on the Done button when it activates.
  9. Quit Disk Utility and return to the Utility Menu.
  10. Select Reinstall OS X and click on the Continue button.


To install the version of OS X that was currently installed use Command-Option-R. To install the original factory version when the computer was new use Command-Option-Shift-R.
