I'm trying to fix my friends computer, and here's what I know so far:
- The system was fully functional before the error occurred.
- There is ONE dead USB port in the rear of the case, its the one right next to the "type C" port, it was functional before the error occurred.
- The computer cannot boot, the "Over current detected in your USB device, system shut down..." error appears before even the BIOs
- The system has experienced frequent power surges due to the household power being shut off.
- Disconnecting all case USB ports from the motherboard does NOT solve the problem
- Resetting the CMOS battery does NOT solve the problem.
- After removing and then reinstalling all components of the system, the system successfully boots to desktop and is fully functional, but then displays the "Over current" error as soon as the system is rebooted.

We believe the culprit is the dead USB port in the rear of the case, however there's no visible damage. We're unsure of what we can do next.
 
Solution
My only advice is that... if the dead USB port is on the case, just unplug the cable leading to the dead USB port. If it's on the motherboard itself, maybe you should buy a new one and try again. nope? Buy a new power supply. Still nope? Get customer support or buy the guy a new PC (preferably a laptop that won't be plugged in all the time and getting hit with any power surges).

The power outages are due to the negligence of the homeowner to pay the power bill, but that's getting somewhat personal.
