PC not booting after new PSU and mother board

[BarnKnee]

Using my phone right now and not sure how to post pictures, anybody know what could be the problem?

What specifically is it doing? Is it posting? Any errors? Did you replace the MB with the same one, or a different model?

The motherboard standby light is on but no fans are spinning, I replaced my old mobo with a H97m PLUS

Also you may need to re-install the OS.
