Take heart. If you looked at the code under SM you may have seen that it was once more a result of the commonest cause of Sad Mac: nnnnnn0F, indicating a software fault. Hardware faults, although having the lion's share of coded indicators, are far rarer. Hardware faults are far more likely to result in a raspberry or no post-POST chime than a Sad Mac. Complete your examination of the 1400's entrails, and then take your always-at-your-elbow software hammers: Install CD or Boot Floppy Disk or Disk Tools, DiskWarrior for hard drive directory repair, PlusOptimizer for file defragmentation, and the like. If you can get hold of the PB's HDD in Target Disk Mode from another Mac, all may become marvellously clear.
