External hard drive does not work on any motherboard USB, only on the front of the case.

I was using the computer normally, when the sound of unplugging some USB came. It was the external hard drive that I always used plugged into the motherboard that suddenly stopped. I restarted the pc to see if it came back, and continued the same thing. I tested other USB on the motherboard, and nothing. So I plugged it into one of the case’s USBs, and the hard drive worked. What would be the problem? When connected to any USB on the motherboard, the LED on the external hard drive is blinking madly. Can someone help me? I asked in various forums about hardware and just got ignored. Thanks.

Hello

How does the external drive work when connected to the mobo,other than blinking? Have you checked the health of your drive lately?

turn the PC off, unplug it’s power cable then turn the PC on, that’ll drain any residual charge.
now plug back in the power cable and turn the PC on.
does that make any difference?

next, reboot the PC into Safe Mode and see if it helps.
if not, create another user account and log in under that profile and see what happens.

how are other USB devices (mouse, keyboard, USB sticks) behaving?
have you got another PC or laptop that you could plug the external drive into and see how it goes?

check inside each of the USB ports with a torch and make sure the 4 pins are all correctly aligned.
