Just recently bought some upgrades for my PC and assembled it all at the beginning of the week. Everything seemed to be working smoothly except for my chassis fans. Originally I could get them to work after shutting down the pc all the way and starting it up again, but now if I do that the fans will spin for 1 second and then stay off. If I try to restart then they don't even move at all. The CPU fan works perfectly fine, but everything is running hot without the extra chassis fans.

These are the parts I upgraded:

Motherboard: Rog strix b550f
CPU: Ryzen 3600x

Extra RAM and SSD to go with a new case. Anyone have any ideas? I'm getting very frustrated with this as the first mobo I got was DOA.
