Most motherboards will pass through the power-up signal to the power 
supply even with non-functioning RAM and CPU, so it sounds like you have 
a wiring problem to the power switch, a bad motherboard, or a defective 
power supply. You can pick up a power supply tester for under $20, or 
try swapping it temporarily with another one to rule that out.

I don't think you're at a point yet where that will matter, but I'd 
recommend scavenging a speaker off of another case for use after you get 
the power issues resolved. Unless your motherboard has a numeric display 
of the POST codes, the beeps will be your only guide to additional problems.
