In the video I only have the power supply connected to the CPU (8 pin) and ATX (24 pin) connectors. I have the CPU and stock CPU Cooler hooked up with the fan plugged into the 4-pin CPU_FAN1 plug. The only other connection is the 2-pin power switch connector (PWRBTN) going into my case.
The fans spin up, and down, indefinitely until I turn off the power supply.
Here's an image with my two DDR3-1600 sticks in the two blue slots, as well as a DVI monitor cable, USB keyboard and mouse and all of the case plugs (PLED, HDLED, RESET). Same result, fans spin and stop.
I bought a new 650W power supply at Best Buy, but I got the same result. At least I know it isn't the power supply.
I took the CPU out and made sure there were no bent pins, and that the arrow on the CPU went with the arrow in the socket. Re-seated CPU, same result, fans spin and stop.
The motherboard is out of the case (to make sure nothing was shorting out). Same result, fans spin and stop.
Set the CLEAR CMOS jumper and took the CMOS battery out for 30 minutes. Put them back, same result, fans spin and stop.
Halp!
