There are various Apple Support Knowledge base articles that address this matter. The thing is, it really comes down to understanding the startup process and then determining where the problem is occurring. For example, there is a system initiation session, which includes Firmware, Booter, Kernel and System LaunchD processes, and the User Session, which includes the Login Window, User LaunchD and User Environment stages.
There are specific steps to take to determine where the problem is actually occurring in startup, but I don't know if there is a master article that addresses them all. Also, some diagnosis methods are not accessible to the blind, since VoiceOver, for example, is not available during Safe Boot or when using a startup in Verbose Mode. Take Care John D.
