Restart the computer holding down the command - option/alt - P - R keys before the gray screen appears. Continue to hold until you hear the startup chime for the second time.

                                

Reset NVRAM/PRAM

 

You can also try a SMC reset. The article covers when this is required, but doing this will not affect anything.
