scary crash...

[raz25]

Something weird just happened to my iBook...:
- strange stripes suddendly appeared on the screen, and then It went blank (black), It would not wake up so I kept the start button pressed for a while to make it restart....I heard then a fan noise, but It restarted properly....

What could it be?
(for info: the HD on this computer crashed and died 4 months ago and it was replaced with a new one).

It could have been a kernel panic or video crashing for some reason.
Has it done that before?

[raz25]

no, never...
what's a panic kernel?

thanks....found the panic.log, here you go:

Wow you learn fast
You have had one kernel panic on your computer for some USB driver issue but that was on 22 February.
So probably this time the video froze, or the windowserver had something odd happening there, or there might have been some pressure on the video cable. Bottom line that if this has happened only once and will not repeat, I wouldn't worry too much.

That's a OS X Kernel Panic. It's like the Blue Screen of death on Windows.

Has anything bad happened though like data loss?

Depending on what model iBook it is, it's possible that you have a bad motherboard. I had to return my old iBook to Apple to get the issue fixed (bad video processor, or something...), but they did it for free and apologized kindly.

1. No, I did not get this image on the screen, It just went dark...after the stripes, I think I was using Acrobat when this happened.

2. No, I did not have any data loss
