Hey everyone Not total tech rookie here, but by no means an expert. A few days ago my macbook pro mid 2010's started crashing. Suddenly full black screen and constant beeping - I looked it up and it was probably a RAM problem..? Anyways, I couldn't get to a service yet but it started up after a few hours just fine but chrashed again, same black screen and beeping. Now it only starts up and shows the - hopefully - attached message. What could this problem be? I haven't altered anything in the hardware, haven't updated to Sierra OS, I'm on the newest El Captain... Does anyone have any suggestions?
