Cannot open the macbook all the way
My Macbook when I open it appears with ? symbol. Then I applied the pressing the button Option + Command + P +R and it was appeared on. But then I tried to fix the utilities backup it didn't really work. I decided to turn off and restart again and follow the steps that made it on earlier but it didn't work. The question mark was appeared again. What else should I do to recover my macbook in order to set up again what it supposed to be? Is there any other options of opening it rather the step I used earlier, option + command + P + R? Appreciate very much your help, please.
