Hello Everyone! This is my first post here I'm hoping that some of you might be able to help me out with diagnosing what might be the trouble with my iBook G4. Its an 800Mhz model with 1.12GB of RAM. I got my hands on this iBook from a person on Ebay who was selling it for parts. She said she had sent it to a repair place to have the hard drive replaced and that ever since it had returned it would not recognize the hard drive. Since I'm accustomed to opening up computers I figured it might be a good deal if it were an easy fix. Before I purchased it I roamed around the forums here and found out many people had trouble with iBook G4's and bad hard drive cables. Since it was a brand new drive inside the iBook I figured that I would replace the hard drive cable and that it would be an easy fix. Not quite what happened though. After disassembling the iBook I found a few missing screws which wasn't really any big trouble at all. When I got to the hard drive cable I found that it wasn't plugged in! So I reconnected it with the tape and hoped that it would be a lose connection. After reassembly I discovered it didn't work so I ordered a replacement hard drive cable from iFixit. After I received the part I opened up the iBook again and installed the new hard drive cable. The tape had lost all of its adhesive and fell off. I succeeded in installing the cable regardless. When I booted into the Tiger installer I was happy to see it recognized the hard drive so I started the OS installation. The installation failed to my surprise and when I rebooted the iBook I found that it no longer recognized the hard drive. Accepting defeat I went to sleep and before I did any drastic I would try again the next morning. The next morning I tried it again and the installation succeeded and it recognized the hard drive. When it attempted to reboot into the fresh Tiger install it froze. I tried to boot the iBook up again after a few hours and it successfully booted to the desktop. I figured everything was working now and left Software Update to bring Tiger up to 10.4.11. When I came back to the computer though I found out that it froze up yet again. Ever since it seems I can boot into the OS for only a few minutes at a time before it starts automatically closing programs, locking up with the spinning beachball of death, or freezing solid. I cant immediately attempt to reboot after lockup because it will bring me to the boot screen and freeze or bring me to the question mark screen like I have no hard drive. I always have to give it an hour or so. Also Airport seems to have stopped working though the card is all connected. So what do you think is causing the freeze ups and intermittent kernel panics? I keep thinking that its either the hard drive cable is loose or that the logic board is totally shot. Any ideas on what it may be?
