ASUS B85M-G Plus shuts down in 15 seconds

ASUS B85M-G Plus shuts down in 15 seconds.

It is not 822 472 exclusion damage after testing. S_usb_oc# 3.3v is divided by Urn63 urn64 to the bridge. Test urn63, that is, 472 exclusion resistance, 4-pin 5v usb voltage is not 5V. Test that the 5V output of UF33 and UD103 near usb interface is normal. These four feet do not lead to other places. I think it’s disconnected. Directly RN63, 2 feet, 4 feet and a lump of tin.
