localhost com.apple.launchd[1] (com.apple.SystemStarter): Failed to count the number of files in "/System/Library/StartupItems": No Such File or Directory

That's the last error message I get when the I boot till it freezes
How do I fix this error?
I'm using 10.5.1 by the way because 10.5.2 doesn't want to boot at all(Blinking cursor have tried anything already)
