Start a computer with a screwdriver

Hi, I disassembled my computer to take a flight.
I just reassemble all the computer on a box and so I have to start the computer with a screwdriver. But nothing happens...

The hardware seems to be alimented since I see the green LED on the motherboard...

I think I forget a connection but which one,I don't know...

Here is a photo of a part of my motherboard : http://www.video-65.com/Photos/p1.jpg

Do you know what is the problem?
And do you want any other information or photos?
Thanks :-)

PS : my motherboard is Asus P5K but I don't have the documentation with me so I must have done something wrong...

In fact, I am not sure I touch the right leads. You can see a picture of what I touch here : http://www.video-65.com/Photos

There is also a picture of my entire motherboard...

Now can you help me? :-)

It doesn't work :-(
I tried with different tools but how can I be sure there is no painting on them?
Or maybe this is another issue...

Go to this link and identify your exact motherboard. Then you can select it and it will show you the product information for the board. Select the tab that is labeled Download and then tell it what OS you have. One of the items that shows up will be labeled Manual. Click on that and then you can find the current manual for your mobo and download it. Once you have it downloaded you can print it if necessary.

check make sure there no loose bolt or nut anywhere on motherboard, flip it over blow on it, shake make sure nothing under it as well
