New CPU and motherboard. No display

So it was about time to upgrade an older computer.

Purchased a new motherboard and new CPU for it.

Now when I try to boot, I get nothing. No display error.

Tech specs

Motherboard: MSI PRO B760-P WiFi DDR4

CPU: I5-3400F

Graphics Card: RX 480

Power: EVGA 100-W1-0500-KR 500 W1

RAM: Kingston fury ddr4 8gb

I checked everything on PCPARTpicker and didn't bring up any conflicts.

I've taken everything out, reseated etc. with no luck.

What am I missing? I know I've done something wrong but not sure what.
