I was trying to plug in a USB drive into the front USB 3.0 port and received the message of a power surge from the USB port. After resetting the port, I attempted to plug the drive into the second front USB 3.0 port, received the same message, and reset the USB 3.0 port again.
I then tried to plug a different USB drive into the first port, received the same message of a power surge, and reset the port again. However, this time the computer shut down.
I attempted to reboot and at the loading screen I saw a message saying something along the lines of that BIOS detected a power surge and the computer will automatically shut down (before getting to the Windows logon screen). After it shut down, I tried to turn it back on, received the same message, and it shut down again.
I pressed the power button again (hoping to get into BIOS to see if there was anything I could do), but it would not turn on at this point. I had a 'blink' of light from the power button, but the computer would not boot.
I proceeded to remove all non-essential parts to see if I could determine where the power issues were coming from. Finally, I realized the USB 3.0 cable to the motherboard was the 'cause' of the problem. The computer would now boot and load to Windows, but my USB keyboard and mouse (which are plugged directly into the motherboard via rear USB 2.0 ports) no longer worked.
After another reboot, the keyboard and mouse were being recognized in UEFI BIOS, but not in Windows. I changed a few settings and got them working.
I examined the front USB 3.0 ports and it appears that some of the prongs/tines(?) have been bent out of shape, and may be making contact with each other. It's difficult to see clearly. I'm assuming I damaged them trying to insert the USB drive.
Sorry for the long post, but I wanted to provide as much detail as possible.
Does anyone have any recommendations what I can do to repair the USB 3.0 ports? Is it a lost cause? If so, should I invest in a new case?
If the USB3 pins are bent or out of shape, then there is very little one can do besides tinkering with them, I would however if the mainboard is still within warranty to return as RMA and obtain a replacement board and not say anything about the occurance. I would just indicate in the RMA form that either the USB3 functionality is not working or pins in the USB3 connectors are bent out of the box.
Or spend 30 smacks and get a USB3 card and move on.
