I have replaced my motherboard and CPU and my old motherboard had a 2x2 pin outlet for the CPU power and the new motherboard has a 2x4 pin outlet. I only have a 2x2 pin connector so I got an adapter that converts the 2x2 to a 2x4 and it still doesn't boot up. It will start to turn on for about 7 seconds then will turn off and try to turn back on again. I don't know what to do now.
