  • Lost USB 2, then power to the computer

    Win 10 Pro desktop with ASRock Z97 Extreme6 motherboard. Yesterday I lost the case's front USB 2 ports, but not the USB 3's (I didn't check the back USB 2 ports). Today, while trying to figure it out I mistook the USB 3 board connector for the 2 and moved it to another USB 3 port on the mobo and started up. It ran momentarily then shut down, with the red power and reset lights showing. I turned off the computer's power switch and moved the USB 3 connector back to its original spot and pressed the case start button. No power at all. My first thought was a blown fuse, but I'm not finding one on the board or in the manual. Maybe the battery? But how does it come out? I've removed the graphics card but the space is tight. Thanks,

    Follow up: it's not the battery. The only other thing I can think of, short of the PSU having crapped out for some reason, is the Thermaltake case start button. For the past several months, pressing on its left side starts the computer then it stops, while pressing on the right starts properly. I don't see a way to get to it, certainly not easily.
