I have a gigabyte P55 board with core i5, 4GB OCZ DDR3, ASUS ATI 4300 series PCI-E card, and blu-ray drive hooked up to a power supply for testing parts. However, when I temporarily short the power pins to start the motherboard, it comes on (cpu fan kicks on, blu ray drive starts to spin) and turns off immediately and keeps cycling through this until i turn off the power supply. The mother was placed on the anti static bag on a couch. Also, I didn't have a case fan hooked since it was out in the open. Just the CPU fan, monitor, and usb keyboard were attached to the motherboard along with the SATA blu-ray drive with gOS CD inside it. Does it need to be grounded or something? I want to test the components before I rip apart my existing system.
