My computer won't start up...

I restarted my computer after installing “IOUSBFamily Log release for Mac OS X 10.5.5 Build 9F33", the grey screen with the apple appeared, but before the "loading circle" thing appeared, my screen dimmed and the "you need to restart you computer" thing came up with all of the different languages. I restarted it, and it did the same thing. I turned it off, unplugged it and plugged it back in, turned it on and it came up again. Luckily, I partitioned my hard drive and installed Mac OS X onto it (incase of an emergency). I am able to boot up using that partition just fine. When It finished booting up, an window saying "Mac OS X unexpectedly quit after restart" or something like that. I opened up Disk Utility and Verified the disk. It said it was OK. I restarted my computer on the problem partition, and it still came up. The next time I booted it up on the "emergency" partition. and copied the error report:
