Howdy- Today, went to do a clean install of OSX on my Powerbook, as it was getting a wee bit buggy. To begin, the 10.4 install disc was demanding I put batteries into my BT mouse and use that. Luckily I had one, and obeyed. After a few tries I got it working and continued with installation. Installation proceeded without a hitch, afterwhich my PB restarted. It froze at the Mac OSX startup screen at "Starting OSX", progress bar at about 10%. I performed a hard restart after a few minutes, and it happened again. I then used target disk mode to perform a second clean install from another computer. Installation was fine again. Restart. This time, the original PB got past the startup screen, but froze when the dock was halfway up. Restarted, the dock got all the way up, but no menu bar. Restarted, no progress. Disk Utility says the disk is fine, I can even use the HD as a boot disk for the second PB. What is going on?? I can't seem to find any history of similar problems in the forums. Looking like it might be MBP time... Any help greatly appreciated.
