Hello. First you’ll need to find what exactly is wrong. It could be many things (Motherboard, SSD, NVRAM etc) First try resetting the NVRAM:

  1. Find the “Command”, “Option”, “P”, and “R” keys on your Keyboard.
  2. Turn on your Computer and hold down Command-Option-P-R together straight away.
  3. Keep holding this down till you hear the start up chime 3 times.
  4. Release the keys.

If this doesn’t work, try booting from the recovery:

  1. Find the “command” and “R” keys
  2. Turn on your computer and hold both keys straight away.
  3. Hold them until the recovery starts to boot.

If the recovery doesn’t even boot then there is something else wrong perhaps the motherboard.

Did the recovery boot? If it did then that proves the motherboard is fine and it just can’t boot anything from the SSD. Yes if you want you could boot from a USB because that would also prove that the computer is fine, just not the SSD
