MacBook beeps
My MacBook started to beep after I opened it last night. The screen froze and it continued to beep. I pushed the switch-off button and it shut down. I turned it on again and this time the screen turned all white while it was still beeping. After about 1 minut it stopped beeping but a map with a question mark came up. What should I do? Does anyone know what is wrong?
