Did you boot from your Leopard DVD to run Disk Utility to both repair the drive and permissions? Open your Console application in the Utilities folder and locate the panic log. Post a copy of the most recent kernel panic. Omit all the system information that comes after the panic information. Also note the timestamp for the panic. Then in the console log look for any entries right around the time of the panic to see what software may have been associated with when the panic occurred. Post that as well (just the immediate stuff up to the time of the panic. Should only be a few lines.)
If it's not possible to get the computer to startup at all without a panic, then most likely there are damaged system files. Try booting into safe mode if you can.
So you cannot boot into safe mode without a panic, but you can boot from the installer disc without any problem? If that's correct then it's not likely a hardware problem. If you repaired the drive satisfactorily, then you will need to try a couple of things that may help:
Delete caches to resolve some startup problems:
Boot into single-user mode. After startup is completed you will be in command line mode and should see a prompt with a cursor positioned after it. At the prompt enter the following then press RETURN after each commandline:
If you receive a message that says "*** FILE SYSTEM WAS MODIFIED ***" then re-run the command until you receive a message that says "** The volume (nameofvolume) appears to be OK." If you re-run the command more than seven times and do not get the OK message, then the drive cannot be repaired this way.
If you were successful then enter:
/sbin/mount -uw /
rm -rf /System/Library/Caches/*
rm -rf /System/Library/Extensions.mkext
rm -rf /Library/Caches/*
I suggest you print out the above to be sure you do not make any errors when entering the commands. When in single-uwer mode you have 'root' access, so it's important that you not make any mistakes.
See if that gets you back in business. If not you will have to reinstall OS X:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.
I had something similar on my Macbook 13", i worked on it and did 2 things before installing the OS X:
1) resetting PRAM as explained here: http://support.apple.com/kb/HT1379
2) reseting SMC as explained here: http://support.apple.com/kb/HT3964
then I could install and run all the updates... u might have this problem of Airport disability and it's because of the update, so better to do all ur updates while working on ethernet.
i have tried to boot it into Single User Mode, Holding the command and S button a black screen came up with white text on saying something about the Kernel Panic, the laptop also didnt let me type anything. (this is weather i have done it right)
i reset the pRam yesterday ( if i done it right) this never done nothing, i havent even tried to reset the SMC? because i dont know where to start.
To reset the SMC see: Resetting MacBook and MacBook Pro System Management Controller (SMC).
However, if you are unable to get into single-user mode successfully then the OS is hosed. In that case you are back to the Archive and Install option I outlined earlier, but only if the hard drive tests out OK when you repair it with Disk Utility. Otherwise you have to erase the drive and then reinstall OS X.
Ok, i will do the Archive & Install,
Will this get rid of all my files & Photos
Get rid of my applications?
What will this acually do to my laptop.
I also have forgot to mention, that since the Kernel Panic appeard a red light through the audio headset jack, on the left hand side, i have researched it but i dont understand. Could this be somthing to do with the Kernel Panic?
No, it will not erase your hard drive nor get rid of your applications or files. If you read the links included with the procedure it will explain everything. And I suggest you read everything carefully before doing anything.
The light in the jack is related to the digital audio. It turns on when digital audio has been enabled through the Sound preferences. It has nothing to do with the kernel panic.
The Archive and Install preserves users and documents; it merely replaces the system components.
The red light in your audio out suggests that you need to reset that port. See this thread for how:
ok, this is what i will have to do. The archive & install
But first, What could of casued this Kernel Panic, the only thing i can think of is installing windows 7 on a partition. The kernel Panic happend the same day.
Is there anything eles i can do to try and solve, have i done everything that can be done?
Thanks to everyone that has helped.
Since you did not post a copy of the panic log from the Console application it's impossible to know what caused the panic. It's highly unlikely installing Windows on a Boot Camp partition would have anything to do with it unless you managed to format your OS X partition instead of the Windows partition.
Do the Archive and Install. That will solve your problem.
