Keyboard and mouse won't work.

[Ctg1171]

I updated a few of my drivers like my NVIDIA 660 driver, sound driver etc. When I restarted my computer my keyboard and mouse wouldn't work. When I go into BIOS everything works fine. Any one heard of this? What can I do to fix it.

Sounds like your USB system is not working - I'm assuming your keyboard and mouse are USB devices. Re-install your USB driver.

Yes they are both wired USB devices. How am I suppose to re-install them when I can't get into the computer.
Also I have Win 8.1.

You need (temporarily) to use at least the keyboard as a PS/2 device. On the back panel of your computer there are probably two little circular ports for 6 pins, one each for keyboard and mouse. These ports are always active - your BIOS takes care of that, and Windows always has built-in drivers for them. You could do it either of two ways. One is to borrow or buy a cheap keyboard already equipped with a PS/2 connector on its cable. The other is to use an adapter. This works because electrically the connections for USB2 or PS/2 ports are the same, so the adapter only has to convert pins and wires. It has a socket on one end for the USB connector and the round PS/2 connector on the other. It's cheap at computer shops, or you might borrow one from a friend, or you may already have one - many keyboards and mice with USB connectors come with this adapter in case you need it. Personally, I use my keyboard via the PS/2 port all the time to preserve USB2 ports for other stuff. I can't for my new mouse, though. When I had to replace my failed original mouse, the new one only works on a USB port because of some design differences.
