Everything was going smoothly until I tried to add fourth hard drive to the system's fourth bay.  I tried to turn on the computer again - white power light came on but it didn't boot from the drive.  I took out the 4th drive bay and tried again but it will still not boot. This was possibly the first restart in a while so it could also be an update from a piece of software also.  It does not appear to be accessing the hard drives at all. I have removed all external USB sources and I still get nothing.  i have tried removing all but the first(system) bay and it stll won't boot.

 


Any ides?


Thanks!

    Do you get the chime?

    Do you get the gray screen?

    Do you get the dark gray Apple?

    Do you get the gear?

    Does the gear spin?

    Does the gear spin for the usual amount of time?

    If you have no chime you have a very fundamental problem.

     

    The chime is generated in software after millions of instructions have been exectuted and the first part of the power on self test has passed.

     

    The fans are set to high by Hardware at power on to avoid damage if the software crashes. They are re-set based on measured temperatures when the software runs or continues to run.

     

    To make progress, remove everything that could be dragging down power including the graphics card and all drives. If no joy, back off to one set of DIMMs. You are looking for the chime -- without that, you get nowhere.
