CPU problems HELP!

[Bootyslappa]

I recently bought a new CPU (Ryzen 7 2700x) and put it in my pc with the wraith prism cooler. My PC won't turn on! It's not a problem where I can't post, there's no power going to the pc it's self because when I have the plug and psu on the fans don't light up or start spinning. My usb ports re getting power though because my Corsair k70 is rgbing. I have checked if I knocked my SSD (as that is my boot device) but I haven't. I plugged in the CPU fan header into the right slot, ram is inside safe, GPU is in fine. My power supply is a bronze certificate be quiet! 600watts. Do I have to update my bios or something. My Mobo is an ASROCK a320m HDV because I'm not interested in overclocking. Maybe I have to reset the bios as I first plugged the CPU fan into a random 4 pin fan header?  I know that it's not my CPU that has a problem. I think that it's my mobo, but I'm not sure. I might of broken a connection pin on the Mobo CPU socket. Please help.

You do need to update the bios, but there might be another problem because the system should still try to turn on, it won’t post but the fans should still spin up.
