Re: new motherboard
What is the make and model of your power supply? Try jumping the power supply, to see if the power supply, is the one with the problem. You do this by unplugging your power supply from the computer and wall socket. Turn off the power switch....and then stick one end of the paper clip or wire, into the green pin of the main power connector. I think it's the 14th pin....and then connecting the other end to any black (aka ground) pin. Then flip the power switch on, for 1-3 seconds only....and then flip it off. Then connect the power supply, and see if that works. If it doesn't, report back.
When you press the power button in front. Does fans spin?
