Motherboard is creating electricity apparently (flashing it onboard LEDs and desk light while no power is connected)

Started happening recently when I would turn my psu off these two lights plus my webcam lights would just start flashing and would only stop when I would turn my psu on again and my pc run fine otherwise. As I’m writing this the lights have been flashing for 20 minutes nonstop without the psu connected to power. I don’t think motherboard capacitors are able to hold this much power but the board is completely disconnected from the psu so idk

 

motherboard: asrock b550 pro 4

PSU: cooler master 650v

CPU: ryzen 5 3600

 

Also please ignore the bad bottom fan placement I know it’s wrong

You likely have a poorly designed peripheral that has its own power source and is backfeeding power into one of the ports.

AND....most likely its USB cause its a always powered connection and it can go backwards back into other components instead of just forward. That CM V unit is a very good platform and psu but it cant stop this with something thats not plugged into it.

Ya figured it out thank to you guys, mark Zuckerberg just create a sh*t product and my quest 2 being plugged in to my pc is what was causing the problem.
