Slowly getting my breath back.....
I opened my 17" PB from sleep and the screen wouldn't turn on. I switched it off and rebooted and the proc started making weird noises and spat out the disk that was in the drive.
Then, after switching it off again, it started but there was a 3 inch blue stripe down the left hand side of the screen. The Apple Logo was pushed somewhat to the right.
Then, once it got into the log on screen, the screen was flickering all over the place and there were about 10 cursors all over the place.
I couldn't get any further.
I took the battery out and disconnected from the mains and then connected again and rebooted. After a long start up time, everything seems fine again.
Anyone have any ideas of what it might be?
