I brought my MacBook air home from school cause I got a new charger shipped to my house. I plugged it in and then opened my MacBook. When it turned on, there was a grey folder with a question mark flashing. I figured out how to get around that. It loaded one time and then I tried to do a restart and now it will get to my account and password, then load half way and stop. Eventually it turns itself off. Is my ssd going out? I can verify and repair it in disk utility.
