built computer using d945gclf2, but no video

I just put together an M300 case with a d945gclf2 mobo, 2gb ram, pico psu 120,  and a WD3200BEVT  HD.   The box powers up okay, however, the power light blinks 3 times every 3-4 seconds and I cannot get any video. I have tried both the vga and svideo.  Any ideas?  Thx.

Here my troubleshooting procedure :
i suggest testing with the minimum setup - disconnect also all peripherals and network cables :
motherboard + cpu + 1 ram stick, video card, power supply
verify that the 4-pin cpu Aux power plug is connected
on boot, do you have a display?
if NO it is one of the connected, swap ram, Power supply, video card or monitor - leaving only motherboard and cpu
if Yes, add devices till the problem shows

you can also check the motherboard for bad capacitors as shown here :   www.badcaps.net

Nobus, thanks for the comments.  I have tried the unit with the barebones -  the motherboard and power supply and get the same results.   The store I got it from said they tested the video before sending and that it had worked.    I also tried with just the mobo, 1 ram, and power supply with the same results.  The 4-pin cpu is plugged in.  

One question, for anyone using a pico-120, do I have it plugged into the correct pins?  The pico is smaller than the motherboards connector.  I have attached 2 pictures with the configuration.

I will check the capcitors next, however, I was assured the board was working, so I wanted to confirm the power supply is correctly connected first..

thanks for the replies.  I followed the above comments but was not able to resolve.  I have sent back the computer to the company so they can test each component and address what is required.
