In most cases like this it its the motherboard or the cpu.  If you have another CPU try swapping it.
Step by step to verify:
1. Remove the connections to your drives (make a note of where each one goes), remove any PCI cards except the video card and try booting.
2. If you still can't boot, remove the videocard and try again... make a note of any beep signals you may get.
3. If you still can't boot remove the memory cards and try again... make a note of any beep signals you may get.
4. If you get any beep signals after doing any of these then report it here without going on to the next step.
5.If you still can't boot, then it's down to the motherboard or cpu.
Let us know the results.
