The way it normally blink just before the login window appears or (if auto login is on) it gets me to the desktop. The reason for this is that the blue screen was 'blinking' every half minute or so. I could hear the hard drive working, but it appeared to be stuck in some sort of loop. Just to be sure, I let the machine keep trying for over a half hour. After installing the latest Security Update 2008-002 v1.1 (Leopard) via Software Update I would not get past the blue screen after restarting. I just got stuck with the same or a similar problem. Nope, i cant get into safe mode, no way to access any menus because it freezes before the desktop.well i was able to back everything up, i also used another external system restore the image of the drive to the external, im gonna reinstall tiger and see if i can migrate my stuff over.also, i repaired permissions and it didnt work =/
