PC won't boot: dead mobo? PSU?

So I was out this morning, hunting those after-Thankgiving deals...

I bought a DVD Burner and tried installing it, but somewhere down the line, things went horribly wrong.

When I had finished installing it, I tried to power on with no sucess; no fans, no led's. nothing.

My first instinct was that the power supply had gone. I removed power from all drives and tried again, to no avail. I took out all PCI (and AGP) cards still to no avail. Right now, I have the bare mobo, no RAM, (but with CPU), hooked up to the PSU, and still nothing. Yet, when I connect the green and black wires from the PSU connector, the PSU fan comes to life. Is that the only determinant of a good vs. bad power supply? Could it still be a problem with the power supply?

I already tried removing the mobo battery for a while. Also, I hooked up only the PSU and mobo, and tried just shorting the case power jumper, still with no success.

Is there anything else I can try? Is my motherboard fried? Could it be anything else?

Unfortunately, I don't have any spare parts to troubleshoot with. I don't have the resources to go out and buy a power supply or mobo and then have it turn out it was the other one. (the selection is pretty bad around here too)
