Motherboard won't boot if USB3 on rear IO is populated


#1

This motherboard keeps crashing and giving me the USB bug code message. And if any USB3.0 on the rear IO is populated, it won’t boot at all. Sometimes after a crash, I have to disconnect anything in USB3.0 on the front IO to get it to boot, then I can restart and connect it again.

I am not 100% sure it’s the motherboard’s fault though. The CPU (4930K) and my RAM was on another board before where the AIO leaked slowly over time (the motherboard was horizontal) and I can see the traces of the liquid on the board on both sides, which is why I eventually swapped boards.

Does anyone have any idea how I can maybe figure out what’s up here? It doesn’t matter if it’s an fresh Windows install, it’s the same regardless.

Oh, btw, the motherboard is the ASUS P9X79 PRO.

I have a ASUS P9X79-E WS which dropped to the floor, and a pin or two is bent in the socket, so I haven’t dared try it again. Could it possibly kill the CPU, or just not boot if actually broken? I have tried to fix the pins somewhat.
