Zotac and InWin not playing nice

I have a zotac NF610I-K-E http://www.newegg.com/Product/Product.aspx?Item=N82E16813500044 and a InWin ITX tower http://www.newegg.com/Product/Product.aspx?Item=N82E16811108224 I had a http://www.newegg.com/Product/Product.aspx?Item=N82E16811108225 before the power supply (seemingly) failed. One day after working fine for a long time it turned off and would not even post. First I thought it was the motherboard, since it was not starting up with other power sources. So i replaced it and tried again, now it works on every other power source i had besides the InWin black case. So I figured maybe the power source died and killed the old motherboard with it. So i bought the white case and to my anger, no post. the PSU powers other computers (even some old P3 and a P4 rigs), but does not want to post with this specific motherboard. The light on the motherboard flashes when i hit the power button, then goes out. Any help would be very appreciated!

interesting update, after toying around with parts i have found that the parts work together when certain fans are plugged into both of the fan ports on the motherboard. i have a psu tester and all the voltages were in tolerable ranges, but the motherboard and the psu only work with two fans. now, the simple solution would be to use both, but there is no room for both and they are very loud. can i make a circuit with a resistor on one of the ports to make it run as if there was a fan? when i remove the yellow (speed sense) wire they still work fine.
Thanks again to anyone who can help.

It may be that you have an undetected short on the mobo. If a spike caused some damage to your mobo it might keep operating until it was turned off, and then not work again unless you bridged the short circuit (hence not working unless the 2 fans).

Your idea of the resistor seems rational, but I'd be concerned with such a circuit causing further problems. I take it that your PSU tester (usually a voltage detector) would not detect short circuits. If you have the parts I'd try the mobo out with another PSU to confirm that it is the mobo and not another component.

i have tried the motherboard with different power sources, and then it works fine and doesnt need the fans. i have also tried the power source with different computers, and it works fine. but together it will not post unless two high rpm fans are plugged in. i only have two fans which it works with in this this situation
p.s. all my work is being done outside of the case ontop of an antistatic bag to rule out the possibility of case shorting. The psu tester i have is http://www.newegg.com/Product/Product.aspx?Item=N82E16899261023
thank you for your help.
