To test the motherboard connector, just take the black lead from multimeter and put it in any black connection. Then take the other lead and put it in any yellow(+12v) connection. A good voltage is between 11 and 13 volts, anything outside that and you need a new power supply. Be sure to check all the connections. There could be surges that are so fast you can't see them, it would be a good idea to buy a new ps to keep around anyway. http://www.quietpc.com
