Hello,
I have had the same issue. Flashing to the latest Bios version 115 gives problems with USB ports after a shut down and reboot the PC's usb ports will not work anymore .
So the PC is booting windows but no keyboard & mouse is working.
Reflash to 113 solves the problem but on 113 there are issues with the USB 3 ports when i read the improvements of 115 (the version that is not working)
Dont understand why Intel is releasing Bios versions without testing ?
So when is there a working 115 ?
Thanks
