I assembled a new PC with the X570-E GAMING motherboard. But if I connect one or both of the two USB 3.0 front panel connectors to the MB, the PC won't start. Not even the PSU fan will come on. If I remove the USB 3.0 connectors, the PC starts. The BIOS is the latest.
Are the USB ports just broken? What else can I do to verify? Is it time for an RMA?
Thanks.
