Question No visual or usb power

[Destineddeity]

My PC was working fine the other night, the next morning I went to turn it on, and the PC started, fans lit up fine, but there was no visual on the monitor and no USB power to the keyboard and mouse. I thought maybe it was a bad power supply, which is one of the few things I haven't replaced yet. Today I installed a new PSU and I'm still having the same issue.

Side note, I plugged a cell phone charger into multiple USB ports, front and back and it DOES receive power. However the mouse and keyboard are not.

Hmm, it could be your motherboard maybe?

Thats what I'm thinking, but I don't personally know how to diagnose this sort of issue. I just want to be somewhat sure, because if I replace the motherboard im going to upgrade to a more current mobo and processor, so if there's anything I can do before I spend a good chunk of money, I'm open to ideas.
