Hi,

I put my ibook to sleep, when I opened it up it had locked up, I rebooted and it started up ok but locked up again. Now when I switch on colours start appearing from the top of the screen and gradually move down to the bottom, then it just goes black and won't do anything. Any ideas on what could be wrong?

Thanks

Sounds like a logic board problem to me.

Agree, most likely need a new logic board.
