symptom

Start up the computer holding down the “D” key 

on the keyboard to see if Apple Hardware Test on 

the hard drive will boot. If so, run the diagnostic 

or Apple Server Diagnostics. This will tell you the 

hard drive is working. 
Try starting the system to Apple Hardware Test 

on the Install DVD or Apple Server Diagnostics. If 

so, run the diagnostic. This will tell you that the 

optical drive is working.
Start the computer holding down the Option 

key on the keyboard. If the Startup Manager 

is recognizing internal hard drive and optical 

drive (if Install DVD is in the optical drive) and 

any external bootable drives connected to the 

system, SATA connections and external ports are 

communicating with the logic board.
Remove SDRAM and install Known Good SDRAM 

and start system. This will verify the SDRAM is not 

the cause of a startup issue.
Using Disk Utility on Install DVD or external drive 

to verify SMART status on the hard drive and 

repair directory structure. This will tell you that 

the optical drive is working, and will verify your 

hard drive status and directory.
Boot from another computer of same type in 

Target Disk Mode, or from an external FireWire 

drive with compatible Mac OS. This will tell you 

that your logic board is communicating properly 

with a compatible Mac OS.
