I suspect a failure or problem with the keyboard controller
The system does not respond when I try to reboot it by pressing {Ctrl}+{Alt}+{Delete}
I have spilled coke/coffee/etc. within my keyboard, can I fix it?
One or more of the keys on my keyboard is sticking, bouncing, repeating, or not generating a keystroke reliably
There is a loud ringing or repeated beeping sound from the PC speaker when keyboard is connected to the system
I have a keyboard that I want to connect to my PC but the connector is the wrong size
