Hello, I've had some problems with my computer lately. The mouse and keyboard has stopped working at the login in screen. I've tried everything, gone through many of the related problems people have had. The thing I found most common that helped people was to disable some xhci shit, in the bios utility thing. It didn't work. I'm not so good with computers, neither do I know anyone who are, so there is no point of telling me to remove some hardware, hd card etc. I have Windows 8.1 and for some reason when I want to get in to advanced boot options ( where safe start and default start etc is ) it opens the bios utility. Since I cannot log on to the pc, I can't open it or enable it from there. My keyboard works in or at boot up, so I can spam f8, but then BIOS Utilty comes up, not advanced options, or safe mode. Please try to help an fellow mate in need
