My MacBook Pro refuses to boot up cleanly after crashing. It says your computer has restarted because of a problem, press any key or wait a few seconds to continue starting up. Then it just shows the Apple logo and stays blank. Then the whole screen is occasionally covered in rainbow noise and it shuts down. Please I need help
First see if you can start it in recovery mode. When booting hold down the option key the select the repair partition if it comes up. Next run Disk Utilities on the drive.
