[QUOTE="harryb2448, post: 1324794, member: 42497"] G'day and welcome to the forums. Have you tried SMC reset and a PRAM reset? SMC reset turn off power at mains and remove plug from socket and leave it off for a minute or two and reconnect and see if it starts. To zap the PRAM, immediately after the chime, hold down the Command, Option, P and R keys all together and keep held down until you hear a second and then third chime. Release and if any luck may be a goer. Try booting without the kb and mouse attached. And time machine is not bootable alas. [/QUOTE]
