Description:

Computer will not boot normally to my main drive, only to Safe Mode. Have run Disk Utility from the Recovery partition, reinstalled the OS (twice), reset the SMC and PRAM, confirmed the permissions for the Root drive, pruned the System and Library folders (Extensions, LaunchAgents, LaunchDaemons, StartupItems, etc.) and rebuilt all the system caches with OnyX. When attempting to boot normally, the progress bar at the Apple screen reaches the halfway point, the screen then goes completely grey for a second, then the Apple and bar return but there is no further progress. I am unable to get Apple Hardware Test to run. Have not pursued user elements as I don't reach the Login screen. I am unable to use my original Installation discs as my optical drive stopped working long ago.
