I've bought a z87ext4 mobo + int core i3-4130 CPU. The problem: When I put it together and turn it on it almost immediately shuts down. I have unplugged the memory and it doesn't give a sound. I watched Dr. Debug (the digital code indicator) and it doesn't even light up. I read on internet and found somebody with the same problem after building it but the site gave no solution. Could somebody help?
