The power button having no effect typically indicates one of 2 things:
1. The Clear CMOS jumper/switch is in the clear position (or stuck button in boards like yours)
2. The power protection fail-safes have been triggered.
If the fail-safes have been triggered it is typically because of a short somewhere or an improperly installed CPU. Remove the CPU and make sure none of the pins are bent.
If that checks out the disconnect everything from the board except CPU, RAM, PSU and GPU. Make sure you are using the correct 8pin 12v power from the PSU, it is possible to accidentally connect a PCIe 8pin power with some PSUs where the connector is a bit softer and more flexible.
If you still have no joy then thoroughly examine the underside of the board for anything that could be shorting. The fact that you have power to the board (LEDs light up) but the power switch does nothing indicates a safety feature is preventing damage to the system should the board attempt to power on. It could be anything from a bent over component leg under the board (from a capacitor for example) that is shorting to a screw that fell on the board somewhere and got lodged in a place that created a short.
Good luck
