Number keys not working

My number keys one-four and seven to zero, of my numeric keys, the numbers one and four of my number pad and my down and arrow arrow keys aren't working.

They appear to work on certain occasions but not on others. I can't pin point an exact reason for them to not work.
Any suggestions would be great.
