The USB 3.0 header doesn't fit completely...
Did you adhere to the instructions precisely? The USB 3.0 connection on the motherboard seemed incomplete at first, but it actually connected properly. The header didn’t click or anything, which might make it look like it wasn’t seated, though it is. It could also appear slightly misaligned by a few millimeters. USB 3.0 connectors are relatively fragile, so handle them gently. Do the USB ports function correctly?
