Hey all!

My beloved iBook 1.33 wont boot, has flashing ? and freezes when I try to boot from original CD with a bunch of vertical lines. I ran the diagnostic DVD and it says Invalid memory access. I removed the external ram chip for computer and still get same error. I also zapped PRAM, reset NMVU (whatever it's called). Can anybody help me PLEASE??????? I already have the iBooks case open and willing to try anything.

Here is the freeze screen when I insert the original start up CD...

I hate to say this but it seems your motherboard is on it way out. Since you can't replace the onboard memory.

Sorry, but once your logic board dies your machine is practically dead unless of course you get if fixed where you might as well get a new(er) machine for the money it would cost. But that is what it sounds like is the problem.

It may just be a pinched cable in the hinge.

take it apart and reseat the cable.

Since you are getting video, it isn't the video chip.

Google around but I think it is fixable.

xlr8yourmac has a fix it for the video chip.
