I have a 1.87GHz Core Duo Mac Book Pro. It turns on but only shows the grey screen with the apple logo and hangs. Both when booting from the Hard Drive or Recovery DVD.
I used Command D for the Hardware Test Utility and that reported No Troubles.
I used Command V to watch it boot and it gets stuck at "ACPI:System State [S0 S3 S4 S5] (S3)"
Can anybody advise what the problem may be.
Also it also shows "Previous Shutdown Cause: 3" but not every time.
Thanks
