Today I connected my new Nexus fans to my Asus P5k Deluxe Wifi/AP motherboard and ever since doing so, my motherboard will not power on. The power fan connectors on the board are 3 pin and the fans are four but in reading it seems this fourth wire is just for power control. The green light comes on on the board but nothing happens when I press the power button. I cleared the CMOS disconnected all the power to everything for an hour then connected on the motherboard and CPU power back and still nothing. Guessing this is fried? Any suggestions? thanks.

Also tested the PSU which was okay. Forgot to mention that.
