Motherboard Power LED Blinks 3 Time Help Please!

I recently purchased the parts to build a Super Nintendo PC pretty much like what is shown here SNES PC BUILD. I bought the same motherboard and I purchased a Intel Core i3-3220T. I used the molex power connector that is shown just like on the video. The system powers up just fine but nothing is displayed on the monitor and the power LED light constantly blinks 3 times. I looked that up and it looked to be a memory problem with the way the light blinks. I realized I purchased DDR3 1600 and the DH61AG motherboard only supports 1066-1333 memory. I figured that was the issue so I purchased the correct memory and replaced the memory and tested again and I have the same issue with the light blinking 3 times. I am just hoping someone would have an idea of what could be happening here.
