Disconnected and cleaned pc, usb plugs are not on

[USB_NOT_WORKING]

We tried disconnecting power from the motherboard and we tried turning it on and off again. No power is going through the usbs anymore, even from the back. Everything else works, including the fan, Ethernet, hdmi is connecting. The hdmi is not putting any visuals on the monitor.

update: we tried plugging in a charger, and it seems like power is going though. However, we have tried keyboard, mouse, and controller, and nothing seems to turn on at all
