Some things to try:
1. Make sure your speaker is properly hooked up. Disconnect everything else from the motherboard including the video card, hard drive, memory and any connectors that are not absolutely necessary, including the keyboard, mouse and headers. You should have just the motherboard, power supply, processor and fan, speaker, and power switch connected. (Can't think of anything else you would need).
2. If your power supply has a 120v - 220v switch make sure it's set for the proper voltage.
3. Reset the cmos.
--------------
Power up. You should get beeps from the speaker, if not there's no sense in going on (except to check the speaker).
If you get beeps then install a video card. If you have a spare video card, preferably AGP, try it. If you still get beeps connect a monitor to the video card. You will still get complaints from the speaker but you should at least get some text on your monitor, even with everything else disconnected.
If you get this far then try connecting or installing one thing at a time, (power off, of course) and reset the cmos after connecting or installing major items like the memory. Leave the hard drive for last. When you get to an item that prevents any beeps that should point to the problem.
