Left MacBook running yesterday when I got home it has frozen with a blank white screen I switched it off and on and the apple logo comes up like when i normally log in the the spinning ball at the bottom jst spins doesnt take me to a different screen and its making this annoying screeching noice from the inside.
I switched it off and on again and now it comes up with a box and a question mark on it?
Help please on what to do -
Has anyone else gone through this and able to recover whats on the harddrive or will all that be lost?
Any help is appreciated
