HELP PLEASe

[edinburghdave]

I have a 12" powerbook and just last night it came up with a message saying it needed to shut down, this message was in multiple languages if that helps any. It then brought the same message every time i restarted until it stopped going into OS X and brought me to unix where it wouldn't boot from saying there was alloc mem problem. Now when i turn it on the screen stays black.
If anyone can help it would be great, I have no idea whats happened
cheers
Dave

Try this…
restart while holding the Apple key + the "S" key (without the quotes)

If you get a screen of text…wait until it stops scrolling and then type /sbin/fsck -fy and press return
If it finds problems continue to repeat the fsck command

What you had was a Kernal Panic. This happens rarely but if it happens again try to remember what you were doing to see if there is any pattern to a particular application causing the panic
