Hi slug348,
Welcome to Microsoft Answers Forums.
We would like to get more information from you, to help troubleshoot your issue. Please answer the following questions as best you can.

· Do you remember making any changes to the computer recently?
This may also happen if the latest drivers for the keyboard are not installed.
First would suggest that you visit the computer manufacturer website and install the latest drivers for the keyboard and check if it works.
