Out of the blue, my pb won't start up. When I press the power button,I get the gray screen with the apple logo..but thats where it stops. No "spinning circle" or anything! I let it stay like that for 40 minutes..and then i shut it off. Restarted holding the "C" key to start up from the powerbook software restore cd.. no effect.. wierd part is..restarting by holding the trackpad button ejects the cd. (which its supposed to do so) Tried resetting the pram as well.. can't even boot in safe mode or single user mode..nothing works. What should i do? PS - my data is backed up on to an external hard drive in a FW/USB enclosure. Can i connect this drive to my pc laptop? Would it erase the drive?
