Try testing the board outside the case.

Try making sure the 24 pin motherboard connector is in properly, I had the exact same issue when I built my PC

Read both the motherboard manual and the PSU manual. Make sure you took every step correctly. Also, check the CPU for bent pins and make sure all of the parts are seating properly. Altough, it sounds like a motherboard problem. Make sure the motherboard isn't shorting.
