Run an Apple Diagnostics or Apple Hardware Test

For other way of solving this, you can run an Apple Diagnostics or Apple Hardware Test to see if anything is wrong with your computer's hardware. Shut down your computer. Turn it on, and before it can boot your desktop, press and hold down the letter D on the keyboard. Your system will run a diagnostic test and inform you of any problems. Depending on what it finds, you can then determine how to fix the problem using Apple's online support or going to the Genius Bar at the Apple Store.
