Hey guys, I just upgraded to an Asus Z97-A and an i7 4790k with Noctua NH-D14 cooler. Whenever I overclock at all, whether I use the AI Suite 3, the automatic overclock in the BIOS, or manually in the BIOS I get a "power surge on USB port" error during stress testing and my USB ports stop working until reboot. I've tried overclocking just 100 mhz, with voltage at 1.25 (temps were great) and still the error comes during stress testing. I did a little research and it looks like it's not just me: http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/66282-asus-z97-lga1150-motherboard-review-15.html
So the guys over at hardwarecanucks found that it's the Intel Extensible USB 3.0 driver that's causing this problem, and removing it solves the issue. I tried unstalling it in the device manager, and usually it let's me select to remove the driver files too, but it doesn't in this case. After reboot, instead of installing the Windows 8.1 default drivers, the Intel Extensible drivers automatically get reinstalled. It seems I can't get rid of them! Any help would be greatly appreciated!
