I always take my PowerBook G4 to class with me for the purpose of taking notes during class. I was connected to the internet there, over the wireless network with no problem. When I got back home, my PowerBook wasn't seeing the wireless network, but I knew it was working because my iMac is connected to it just fine. I tried restarting a couple of times, and actually typing the name of the network into the Airport drop-down menu. This all did nothing, as did repairing the disk permissions. So, I popped in my OS X DVD to boot from it to use the Repair Disk feature. It came up with an error that said something to the tune of "incorrect number of threads." It repaired the disk without any probems, or so I thought (and so it thought). Now, the computer will not function because it runs into a kernal panic, forcing me to hard shut-down the computer. It happens everytime, sometimes during startup, sometimes not until I get into OS X, but always soon after the OS starts. I have the computer started in Safe Boot right now, and it is idling at the login screen ( I have automatic login disabled). I was wondering if anyone out there would be willing to help me out, preferably even over iSight if anyone has the knowledge to help me out, and it would be much quicker than to keep replying from post to post. Screen name is CoreyAtMiamiU if anyone can help. Thanks a ton!
