***MoBo/CPU troubleshoot HELP***


Beta member
I know my power supply is good. I even went to Frys and bought a new one just to make sure. When I connect my PSU to my case fans and DVD drive and I short it with a paper clip the fans, lights and DVD drive turns on. As soon as i connect the 4-pin CPU cable and short it again nothing turns on. I'm really confused. These are all BRAND NEW parts from Newegg.com how do I test the MoBo and the CPU for power??
