Computer only boots when CMOS set to Clear

I just put this computer together yesterday, and I finally had to go to bed last night. The computer only boots when it the clear cmos jumper is set to clear. This is really strange. I have tried to isolate the problem:

I am running the motherboard on the box it came in. I have it plugged in to the power. I have the keyboard plugged in, and I have the monitor plugged in. That is ALL.

What I mean by 'it doesn't boot' is the cpu fan doesn't start, and it makes a wierd sound instead. Also, no lights are on, no beeps, which the manual says is a Abnormal: CPU / Chipset error.

Edit: now that I breadboarded it, all the debug lights are on, so it SHOULD be fine. but the cpu fan isn't spinning and it won't output graphics, so no go still…

P.S. In case you need my specs, here they are:

The problem was the Motherboard Manual. I emailed biostar and they told me to look closely for numbers. There was a one and a three, turns out the CMOS jumper in the manual was flipped upside down compared to the jumper on the motherboard.
