Computer Crash??

[Spiral Girl]

Hi,

I was burning a show in Toast on a DVD and then I tried to eject the disk and I got this message:

The system extension "/System/Library/Extensions/System.kext/PlugIns/Libkern.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.

Then I tried Disk Utility repair disk permissions. The problem I'm having now is that I can't open applications in their original form. I click on to mount disk from Toast Titanium 8.0.1 and then it says the device is not configured. How do I configure the device?

Also was having problems opening applications (that had previously worked) and it kept asking for an authenticate password but wouldn't take the password even though it was right instead the dialogue box kept popping up.

So I went into the system preferences accounts and reset the password, then went into security and made sure all boxes were unchecked. Also changed the computer name which is where I think I messed up my computer more.

Here's where it goes from bad to worse. When I was on Disk Utility I saw something about installing the original OSX Disk to repair the hard drive. So I installed the disk and did a basic hardware test and a more advanced one. No problems showed up. Then I hit either the restart or shut down (it's all a blur right now). When I turned my Mac on I got the apple icon and then it kept whirling and whirling below it like the count down timer thingy.

So I panicked and shut the computer down since I now had the OSX install Disk 1 in there and held down the the mouse button to get the disk to eject. The disk came out but then I got this black screen with all this writing on it and I can't remember all of what it said but it said something like:

too many errors in succession and then my computer name and it says: I have no name!#

Does anyone have any ideas or am I up a creek?

Hi,

I'm answering my own question here. See below:

Well I had this question up on four forums as I was desperate for a solution. I had three options to choose from:

1. To do target disk mode with my Powerbook PC G4 (to restore the data I hadn't backed up).

2. To archive and install using original DVD.

3. To install orginal disk but do repair disk in Disk Utility after booting from the install DVD but I had to have backed up most of my files.

So I chose the option to archive and install and had planned on trying the other two if that didn't work. The problem was I hardly had any GB left on my computer so I couldn't do the complete archive and install like I wanted (I had leave user permissions (or whatever it's called) checked too. I had to do a custom install in that mode and had to uncheck all the boxes except the top one which was the essential programs or something like that but it looked like the most important one anyway.

Good news is my computer is back up and running. I'm able to mount disk images with Toast, play the DVD using VLC (not Quicktime Pro, will reload that one). Got an error when I first opened something in Adobe Reader but it seems to be fine now, also lost Flip4Mac but will get that again as well. Also one disk icon was missing but I've got that back now too.

I'm will probably run Disk Warrior or Techtool Pro to make sure all is well.
