Hi,
I just updated to Windows 8.1 last night. All went fine. Once it had finished it booted to windows normally. I then decided to restart the computer just to make sure everything was okay and sorted.
It took me to the normal login screen. My Keyboard and Mouse didn't work?! I check all of my peripherals and non of the USB devices were working. I have tried multiple times to restart and try different USB's to no avail. I have tried a bog standard keyboard and mouse and even a PS2 slot keyboard and non of this has worked.
Any help on what I can do without losing all of my data?
**UPDATE**
I found a solution that worked for me. If you try this, hopefully it will work!

Hi guys,
I have found a solution to the problem via a person from another forum with the same issue. All credit goes to him for finding this out. If you try what he says it should work fine. It did for me

Hope it works for you all!
It would be nice if Microsoft warned people that moving from 8 to 8.1 could leave them without keyboard or mouse and no obvious way out.
It would be nice if Microsoft tested 8.1 before releasing it with a recommend,
by testing I mean adequate testing.
When I fell into this trap, I spent hours trying to resolve it.
I followed the steps advised the microsoft web site
Finally I had an on-line chat with a "microsoft engineer" - who wanted eighty euro to resolve it!
80 Euros ????
You can very well buy a new DVD of Win 8.1 with that !!!!
I wonder how many others parted with their cash?
Rather than warning about bios, would it not be better to warn about 8.1?
An upgrade from 8.0 to 8.1 disabling USB devices (previously enabled elicited the response:
"contact the computer manufacturer" and "Modifications of the settings are at your own risk"
... which seems incompatible with ...
"Let us know if you need further assistance with Windows related issues. We will be happy to help"Thanks for providing no support at all Microsoft.
Hi there, Silly question but how do you get into advance mode please? our computer just updated and the USB mouse not working, cheers :)
You realize aHCI is the controller for SATA devices right? So disabling that disables access to a hard drive, which in turn prevents windows from booting....
