So today i couldn't boot my iBook, just won't boot. So i booted into safe mode, then restarted. worked fine, but then the screen went nuts, vertical lines moving really fast, and then it just went to a crazy pattern of the blurred desktop. i'm using it now, and it's working fine after a restart, but are there any prefs i could trash to try and fix this problem, it's happen a couple of times today???

Does it work fine in single user mode? Did you have Beachball installed?

I had three versions of this problem on my 800 combo iBook. Apple replaced my video card and logic board (among other things) to fix it, which may be two possible problem areas for you.

Sadly (or happily), Apple replaced my iBook the third time I sent it in within a six week period.

If its under warranty, I'd send it in.
