I do not know if this will help you, but last year I had the following problem:
my 2007 macBook pro refused to boot, no chime, nothing.
I had had read in some mac blogs that my mac was in a series having a defective
NVIDIA graphic card.
I brought the MBP to my local Apple dealer for repair; the
Most likely the graphics card did not get recognised. On a BIOS based PC, the
order is some kind like this:
Power switch is pressed by user
Send power to BIOS
Send power to CPU
Send power to RAM
Send power to Graphics card

Richmond,
I had an similar effect (with a PC) some years ago.
There was short circuit on the motherboard caused by a little screw I
