Frustrating isn't it? I built an AMD setup last week, first time it wouldn't boot as I had the memory in the wrong slots (no mention of that in the manual), then it wouldn't boot because I had left the EPS connector unplugged when I was fiddling with the memory. Oy vey.
Simple stuff first- are all of your power plugs (24pin and 4 pin motherboard, and 6-8 pin video card plugs) connected properly? Is your memory in the correct slots (blue or black)? Next, unplug all of your USB devices, keyboards/mice etc, try to boot? Sometimes USB devices short out. Unplug hard drives, and optical drives from power and the motherboard. Main thing is to isolate the board with only the bare necessities needed to boot-CPU, memory, and video card/monitor and nothing else connected. Any luck? Still a no go, pull the board out of the case. Verify all case standoffs are in the correct position so there are no shorts. Lay the board out on a nonconductive surface (I usually use the mobo box). Hook up power, video card-monitor, 1 stick of memory in the default slot, see if it will boot. It looks like you have power/reset buttons built on the board (nice feature). Go from there, and good luck with it.
Edit: Check voltage on one of the spare molex (4 pin) connectors. Yellow to black should be 12V, red to black 5V.
