Question Upgraded my CPU and now nothing responds.

[Pillarist]

Upgraded my Ryzen 5 2600 to the 5600 on my B-550 Mobo and now I get no response (case lights won't come on, fans don't spin, nothing). Pressing the power buttons does absolutely nothing. What have I done wrong?

Edit: tried connecting everything to an alternate PSU and same result.

Did you install a compatible BIOS before installing the 5600?
