I have upgraded the Windows 8 Pro to Windows 8.1 Pro but the keyboard and mouse are disabled once I get to the 8.1 Licence acceptance screen, thus I cant accept the Licence and have to restore back to Windows 8. Any ideas how I keep the Keyboard and mouse working
the usb ports are completely disabled (no power getting to them) and there is no option to disable USB 3.0 in the BIOS, the USB ports are either enabled or disabled. The Vostro is brand new so will see what answers, if any, DELL support provide.
i.e. when you power up the system can you press F2 to enter the BIOS setup, can you use the keyboard and mouse or does nothing happen when you press F2?

Silly question but have you tried unplugging and replugging them?
Another thing you could try is disabling USB 3.0 functionality in the BIOS and then retrying.
