If loose, shut down and fix.
It is possible you damaged the board when you were moving that connector.
I would pull the cpu's, see if you damaged a contact pin in the socket.
Clear the cmos
See if you can get another PSU to borrow, at least 550w and a good quality one.
Make sure your memory is in the proper slots and seated well.
Check every connection to make sure it is properly done.
Sometimes the smallest errors produce the biggest problems.
Do each change one at a time and then try the system.
Good Luck
Tried with 2 new 600+ watts psu :
antec quattro true power 850 watts
enermax modu 82+

Ram is 8 go new Kingston valueram 800mhz fbdimm in the right slots to be quadpumped (the white ones).
There is no way you can't seat them well.
They were memtested and run windows flawlessly

idem with the cpus, you can't go wrong there.

I bet that the problem comes either from the second cpu slot (1%) or from the power connectors (99%), but there is no way to fix that. I think that the board was already malfunctionning when the other guy sold it to me on ebay.

As an AtX case ges a little cramped with this board in, It is quite difficult to make sure the 24 pins and 8 pins connectors are rightly set. Yet this would not damage the board...

And even with connectors just a tiny tiny little bit loose, a motherboard should boot. Yet, this one would light on but not boot with 2 cpus (and it would with 1).

After I noticed that by just changing the angle of a psu cable, it would power off, I made extra sure that all connectors were not loose...and I made lots of tests in and outside the case (in case of short circuits) but it didn't change anything...I bet there is a loose solder connection somewhere...

Anyway, as I want a rock solid (stab my heart asus) computer, even if I by pure luck I managed to repair the power connector, it would't really be satisfying : there would still be a risk of it doing it again.
