Please provide us with the specs of the computer. What operating system are you running? If it is a manufactured computer, please provide the make and model. If it is custom built, please provide the full specs.

If the keyboard is a USB keyboard, please try a different USB port. Have you tried a different keyboard or tried the same keyboard on a different computer. If so what were the results of this test?
