[QUOTE="Kevriano, post: 1348731, member: 18605"] Exactly that, though you could try resetting PRAM and NVRAM, which may help/stop the issue. To reset PRAM, restart while holding down command, option, P and R. Keep holding them down and wait for the start up chime to ring 3 times, and then release the keys and allow it to boot. Resetting NVRAM is a little different, and is not necessary usually, but try it if PRAM reset fails. Restart holding command, option, O and F (bit of a stretch!). Wiait for a white screen with some text to load, and then type the following commands> reset-nvram (now hit enter) set-defaults (hit enter) reset-all (hit enter) The computer will then reboot to it's start up screen.
