Iv done everything in this list except disk as I didn't get on with my MacBook. Only difference it's made is when I tried resetting the pram the start up noise came back. I get the apple symbol for about 30 seconds before it turns into a stop / prohibited sight . What can I do , this all happened cause my mac froze and so I tried to reboot clearly not worked
