My computer kept refusing the different mice I tried to plug in, so I went into BIOS (where the mice would then work) and I turned off USB legacy recongnizer, or something like that. I saved the settings, restartd my computer, and when it turned back on the USB keyboard wasn't working, so I could not get past the Windows Boot Manager. I tried plugging it into a PS/2 port and the keyboard lights up then but still doesn't work. I tried doing a CMOS battery reset, which did not work. I tried doing a CMOS reset with a jumper, which informed me on restart that the settings had been set to default, but my keyboard still didn't work so I couldn't do anything past read the message. I have tried many keyboards. I have tried to boot from a CD, but I can't get to BIOS to tell it to do so.
I am out of ideas. Might you all have any?

My motherboard is an msi Z77A-G41 should it matter.

I have seen this on quite a few PCs now.
Basically for reasons unknown (but I suspect one of the windows updates) the generic USB drivers get 'lost'

The only solution I have found is to remote onto the PC from another machine and reinstate the drivers, then all will be fine.

RMA your motherboard, something wrong with I/O.
Or try to remove cmos battery and put it back

I've had something similar happen to me many times, it's super annoying.

I'm not sure what USB controllers your motherboard uses, but if it has 2 different USB controllers you could try plugging the keyboard into the other controller (typically there's 1 used for back panel USB, another used for front USB). So if your keyboard is plugged into the back, try plugging it into the front USB ports, and vice versa.

From personal experience I've found plugging my keyboard into the front USB ports usually works in instances when the back panel doesn't.
