System starts when PSU is on.

[Slartibartfast]

So I've got an Iwill MPX2 board here. Right now I just have 2 athlon MP's and 4 sticks of RAM installed. I do not have any of the front switches/LED's attached. For power, this board normally takes a 24pin and an 8 pin (eps) connectors. However, it can be run with a 20 and a 4.

If I attach either just the 20 or the 20 and the 4, and turn the psu on, the board starts up. The cpu fans start spinning, but if I attach the speaker to it I get no post/beep codes. I don't think anything is shorting out, because I just have the board resting on a static bag on my desk.

Anybody have any ideas?

its a SERVER !

More than likely it has the bios defaulted to startup aftter loss of AC power , meaning that if AC fails for any reason (normally a power failue in the commercial AC) upon restoration of AC power the server will automatically boot to restore whatever critical SERVER funtions it was providing.

It is probally very upset it has no video card ??????

Relax. quit screwing with it before you break something. Put it in the case, install the switches etc. and attach all recomended power connectors and enjoy, and if you DONT have a 24 pin with at least the extra ATX 2.01 4 pin power (you can buy a 4 to 8pin eps adapter) go get one.

Check the power on switch for the motherboard isnt stuck pressed in or that you havent connected the wrong switch/button to the motherboard power switch connector.
