First off I want to thank everyone for the most helpful tech forum I have ever come across! Usually I can find a thread for any problem but this time I can't. The problem I have is I just got a new Asrock z 68 gen 3 motherboard with the power button built in. I put everything together and it refused to turn on, I hear a little subtle sound for a second but besides that nothing. I decided to try the motherboard by hooking up the 24pin power wire, 8 pin and cpu fan...it still did the same thing. I laid it on cardboard. I was looking at the wiring underneath and near one of the holes for the cpu fan/heatsink on the underside of the board one of the wires seem to be crushed probably for when I tightened the fan to the motherboard. I can post a pic if needed! Would this cause the motherboard to not turn on at all? I use my old motherboard to test power supply and the standby green light is green..also I did the paperclip test and it turns on all my fans and lights so it's not the psu. Thanks for any help!!!
