Something wrong happaned to your macbook laptop, it seems look like:
(1)froze suddenly
(2)Internal hard drive disk not recognized, not respond any more
(3)freezes takes long to start up
(4)flashing folder icon on boot
(5)got the flashing question mark folder, a sure sign of death when the computer turned back on
(6)didn't boot up properly and the screen displayed a folder with a question mark! Restarting again did not make the folder with question mark go away
(7)boot to a gray screen or keep freezing when it did boot.
(8)A new drive did not solve the problem.
