I’ve replaced the HD and one memory chip 2GB for a 4GB now nothing powers up except the DVD disk drive. I cannot hear the HD even begin to power up and spin even though the power seems to indicate there is a 3rd LED diagnostic bulb lit. Any ideas as to how to proceed?

I think you’ll need to open your system up again and check your connections. Did you have a hard time disconnecting any of the cables? you could have damaged LDVS cable or connector on the logic board.
