Powerbook Crash.

I was just updating my 12inch 1ghz pbook with 256mb + 512mb ram when some error occured said it could not update all components. I decided to restart my computer and it stalled. cleared all my desktop items away and would not restart... tried to do force quit, nothing so i did a hard power off. Tried to reboot and i get as far as the apple and spinning thing but it juss keeps spinning. Cannot get into login.... i tried everything so far...

Attempted safe mode - will not work
Pram reset
PMU reset
I tried to get into single user to do FSCK and the command line reports some login bin errors and juss crashes cant type anything.
Disk Utility from install disk
- repair permissions *reported some issues and fixed
- repair disk *reported no problems


Are there any options which might help me? Thanks.

BTW i currently have Tiger installed.

i wasnt installing ram juss using software update... downloaded some java update then ipod update then some error occured after that said it could not complete the rest of the updates

yeah thats what i figured... i dont have everything backed up but would juss like to grab a few files for school... how do u do that target disk mode would i have to use a mac or could i use a PC? through a network or direct connection like firewire?
