Dell Keyboard isn't responding.

No problem for Bacon. I've had the problem before, and it's quite easy to fix. When you're logging on, turn on the On Screen Keyboard. Login as usual, and head for the Control panel. I'm using Vista, and haven't played around with XP for a while, so I'm not certain how to find Device Manager. Sorry, I can't be of use there. Anyway, search for Device manager and open it up. Make sure your non-functioning keyboard is connected. Find the section that says 'Human Interface Devices', and expand it. There, you should see a picture with an exclamation mark on it. That means that the HID isn't working properly. Right click on it and uninstall the driver. Then just unplug and replug your keyboard, and the drivers should reinstall itself.

Hope that fixes the problem.
