Hi there an welcome

Shut down your Mac.

Find Command (⌘), Option, P, and R on your keyboard.

Turn on your Mac.

Press and hold the Command-Option-P-R keys immediately after you hear the startup sound.

Hold these keys until the computer restarts and you hear the startup sound for a second time.

Release the keys.

Tell me if it then starts please.
