PC won't power up.

[papercut]

I was trying to trade out motherboards today and just decided to go with the one I had, I hooked everything up and now the cpu fan, and main fan turn a little and then stop and the computer shuts off. I was messing with the power switch cable and if I remove it, the computer won't even try to power on but once I reconnect it, it does the same thing and tries to turn the fans but stops and just shuts off. it isn't my PSU because I tried it in another computer and it starts right up. I have an Intel Desktop Board D945GPM. That is about all the information I can currently give about what is going on. I am completely stumped.

Could be RAM or a bad drive.

I figured it out. I took everything out again and did it one by one and then completely closed the casing and it started right up. Not 100% sure what caused my problem. Maybe had a wire misplaced. Thanks anyway!
