So I just got home from work and I'm having a problem while starting up my Mac. When I turn it on it makes the start up sound but sits at a blank screen. The screen is on but nothing shows up. I turned it off and on with the power button but that hasn't done anything. Anyone have a idea on what to do? I tried uploading a photo but it won't let me on my iPhone.
