After isolating an issue on your Mac to a possible hardware issue, you can use Apple Diagnostics to help determine which hardware component might be causing the issue. Apple Diagnostics also suggests solutions and helps you contact Apple Support for assistance.
If your Mac was introduced before June 2013, it uses Apple Hardware Test instead.
On my 15' MacBook Pro (2.4GHz Penryn, February 2008), I've found I can boot into the hardware test mode without having the hardware test disc in the machine. If I press F2 before the startup bell, the machine directly enters hardware test mode. I don't know if this works with MacBooks or iMacs, however.
How to use Apple Diagnostics
If you choose to get more information, your Mac starts up from macOS Recovery and displays a web page asking you to choose your country or region. Click ”Agree to send” to send your serial number and reference codes to Apple. Then follow the onscreen service and support instructions. When you're done, you can choose Restart or Shut Down from the Apple menu.
This step requires an Internet connection. If you're not connected to the Internet, you'll see a page describing how to get connected.
