Hi, I'm new here and this is my first post. I'd appreciate any assistance you might give me. I purchased this iBook G3 used and it won't boot. Symptoms: ~Everything is extremely slow- blank white screen, wait, Apple logo, wait, circle beneath, wait, finally 'prohibited' (no smoking sign) ~It won't boot from CD, initial spinup then nothing, eventually Apple logo, etc ~Won't enter Safe Mode ~Won't boot from an external firewire drive (known to be working). I see screen to choose OS, wait, eventually shows OSX internal drive but not the external, wait a long time to get to the cursor, try to start, back to Apple logo etc I do hear the startup chime when I turn it on, and I do hear a small amount of disk activity at times. I put in more memory, no difference. Any information and suggestions would be appreciated. I'm thinking maybe a bad logic board? With a funky HD, I'm thinking that it could still start from an OS CD or an external drive- but i've been wrong before. Thanks, Michael iBook G3 dual USB, 380MB, 10GB, OSX (not sure which version), no peripherals attached.
