Do you know what is causing it not to boot?
The Computer will give the happy boot chime then it will start to boot on the hard drive but the monitor has grey lines in it. The computer will keep acting like it is booting but never completely boot. It just has the circle go around and around on the monitor with the lines in it. I have rest the PRAM and PMU and the lines changing but still not booting. Tried to boot from external drive but it would not recognize the firewire. Tried booting in target mood to get the data off the hard drive. The computer trying to recognize this PowerBook did not recognize the PowerBook in target mode. Pulled the hard drive and was able to read the data off of it. tried to boot from the Tiger System disk but it would not boot from it. Tried to boot from the external hard drive with the option key held done but it booted the same as the internal drive did. Do you have any ideas of what part needs fixing? Thanks
