I've run into this dozens of times with logitech and other keyboard drivers. Fix? I don't install such.
Another common fix is to boot into the BIOS and try various USB keyboard support. I can't explain why on one machine I have to enable USB keyboard support and another disable it. Truly an area of mystery.

Just recently I came home the other day and my brother told me that the keyboard on my computer didnt work. First thought was that someone was messing with my machine and so I yelled at him. Then as I was going in, it looked like my Keyboard Drivers were removed. So my next thought was that I got a virus or worm or something, even hacked, so I tried to install the drivers but they wouldn't stay in, no matter how many times I installed them and restarted. The keyboard worked fine cause I could use it before Vista would activate, but soon as Vista loaded, it stopped working.
I then reformatted and put Vista in again and it worked fine. Re-downloaded all my updates and Vista worked fine for a bit. Woke up in the morning and once again, the keyboard didn't work. I even went late to work today cause the I couldn't figure it out, then realized that I believe it was an update I got that prevented my keyboard from working. It's a USB keyboard, mouse works fine but the keyboard just won't work. Any help on this would be DEEPLY appreciated.
