Problem with circuit - feeds 5V back to USB through built-in voltage regulator

Problem found - voltage regulator supplies power over USB 5V. This prevents my computer from completely rebooting as it powers the entire computer. Actually I have LEDs on my PC motherboard and ONLY this USB relay board is connected. This prevents the PC from restarting. If you don't physically turn it off, you're dead in the water. @engineering I think you need a diode on the 5V side of your USB to prevent pollution from your internal 24V to 5V voltage regulator.
