Check if you connected the 12V 8-pin/4-pin cpu power connector securely.

If yes, you may have to remove cpu, check pins on the cpu/motherboard cpu socket very carefully to see there is no bent pin.

If you use a cpu cooler with a back plate, insure the backplate does not cause a short. If you use Intel stock cooler that comes with the cpu, there is no need to check for a short for hsf installation.
