Pc not startinf

[tylersb13minecraft]

I just finished upgrading my motherboard and cpu and plugged everything else in, when powered on the motherboard led turns on but the cpu fan and case fan do nothing and my monitor says no signal . What’s wrong?

did you make sure the cpu and mb work together and the bios on the new mb will post the new cpu. pull the mb with one ram stick and it on top of a box will the mb post (rule out a dead short).
