The bios will coach you with a "press f1..." message, unless you have an additional serial or network board installed.
In which case, those cards messages will over-write the onscreen "press f1..." prompt and you'll never see it. You'll have to remove those cards first, to access the motherboard bios prompt.

This could still possibly be a bad power supply, even if the fans and drives spin up. If you have a spare try hooking it up.
the list of things that can cause this are:
bad power supply
IDE error (optical or hard drive problem)
bad card (modem, video card etc.)
The first thing i would look for in this case is blown capacitors. Those are the little things on the board that look like little soup cans, usually with silver tops. If the tops of any of them are bulging or have junk leaking out of them, you have a bad board. If you are handy with a soldering iron you can try to replace them. Not sure if radio shack still sells caps, but they are easy to find on line. I have about an %80 success rate fixing boards in this way.
If the PS change doesn't work, then try it with different sticks of RAM, if you have more than one, pulling one at a time until it starts or you've tried it with all the ram. If not ram, disconnect the ide cables from the board, these are the wide ones usually connected to the HD's and optical drives. If it still doesnt start then pull all the cards. If it doesnt start then, try swapping processor and if still no joy a new board.
