Hi all, I just experianced a really weird fatal crash on my Macbook Pro running fully updated 10.4.11. I was surfing on Safari, minding my own buisness, when the screen started to dim from the top to the bottom. There was a horizontal bar above which the screen was dimmed that moved down--it took about 3 seconds. After which a large warning in ~4 different languages (English, spanash, german, and some asian, I believe) appeared on the screen saying I had to reboot. I then had to force reboot by holding the power key. An odd thing is that even though the sound was muted before the crash, and remained muted after rebooting, the boot chime still started when I restarted the computer. After reboot OSX told me that I had force rebooted, and asked if I would like a report--I said yes, but no report came up. I wasn't doing anything strange with my computer, and afterwards I verified my disk and checked permissions using disk utility--no problems. I've never seen a crash like this before on my mac (or any other), and couldn't find anything on Google. Has anyone else experienced anything like this before? Any ideas of what's going on? Thanks!
