My fiance has an Inspiron 1100 laptop, it's a few years old, but has never had any problems with it before. Her keyboard has suddenly stopped working for no apparent reason. According to the hardware settings everything is fine, but most of the keys aren't working, or are working sporadically, or are working incorrectly. Most of the time none of them work, but sometimes they do, but mostly they don't work correctly. For example: control, alt delete will make the computer beep a few times, and then the right click for the desktop appears in the upper right corner. Sometimes typing the q key will make it type "qwe" or c will become a whole line of c's. It was working fine all day, and it just suddenly stopped. Nothing was spilled on it, the caps lock key works, but something is very badly wrong with it. Thank you for your help.
