When a Mac does not chime, there's no point wasting time with the display or the hard drive. These are not the problem. Nor is the RAM the likely problem. It is either the power supply, the motherboard, or the On-switch. Or the speaker... If you are not getting any activity at all, i.e. the hard drive does not spin up, then you should first double check the On-switch as that is the easiest. In other words, have you tried a different keyboard? How about the keyboard cable? Have you tried it with no mouse plugged in? Sometimes a bad mouse cable can sink the on signal from the keyboard. My Q630 days were back around 1996 so I don't remember. Is there a power switch on the back of the machine? Try that. If it doesn't work, then it is definitely the power supply or (less likely) the logic board. Getting in the case is tricky. Unfortunately, I don't remember how it is done. I think it involved removing the front panel and then undoing some screws which will let the bonnet slide back, but the memory is long gone. There must be a take apart guide on the web somewhere.
