Hello,
Customer motherboard Aorus B450 Pro.
The customer had shorted the USB3 internal connector and started the board.
Board arrived with short on the 5VDual to GND.
After inserting 5V to the board the following was changed.
PCIE PU1 - Asmedia 1480 multiplexer.
Transistors SOT23 next to the USB3 internal port, next to the USB2 internal port and the USB3 Type C driver and power chip were changed from a donor board.
Now the 5VSB is stable. But there is a new to me problem that I am not sure how to fix.
When the PSU is connected to the board, the board starts automatically and the debug LED stays on CPU Led.
How should I continue to troubleshoot?
No schematics is available.
