StocksR4Me has a good point, be sure that the CMOS jumper is set properly. I've gotten motherboards that have had this jumper set and it just won't boot this way, I've tried repeatly. Now most of the manuals warn that powering up a board with the jumper set to "Discharge" will damage the motherboard, thankfully this doesn't seem to usually be the case. YMMV. The motherboard can get into some wonky states that makes it seem as if it is dead. Sometimes discharging the CMOS is just the trick.

Starting with the motherboard out of the case and shorting the 'on' button jumper is very important. If the reset button is stuck down, it won't boot. If the power button is stuck down, it'll boot but then shuts down partway through the boot up cycle. Best to minimize these possibilities.
