Hardware Rear USB Ports stopped working...

[Xanthe]

This is really starting to steam me. Just recently today, my rear USB ports to my custom desktop PC stopped working...I don't know why this happened. I checked the wiring - no problems. I tried to install drivers - nothing. I'm getting pretty pissed right now

My specs:
i5 6400
MOBO: h110m-a
GTX 1060
8GB ddr4 ram

Did the electricity in your area just recently go out?

I got it working.

I swear to God, if ANYTHING is wrong with your computer, NOTHING will start it. After I found my ports stopped working I turned off my computer several times. The last time I turned it off, it would not turn back on. Now I was furious! You'd be wondering what the hell is wrong after you've gone into your computer and re-wired everything for the 3rd time in a row...

So, recently my FRONT panel USB 3.0 stopped working. My computer just then decided to detect that. I found out that by unplugging the front panel USB 3.0 MOBO connection, my computer would start.

I have had USB controllers fail before.

Equally I have had front panel ports short out and that did prevent the system from booting, and if the front panel ports use the same controller/hub as the back one (entirely possible and even probable) then prior to that the controller might have entered a shutdown mode to prevent further damage which would have caused what you saw with the rear ones.

That said one of the basic diagnostic methods for computers is minimal booting -- one stick of RAM, no cables beyond CPU cooler and any graphics one needed, then add hard drive, then add all the RAM... this would have revealed that.
