Up and down keys Not Working

I have a Dell Inspiron 15 3000 series laptop and my up and down keys aren't working. I've tried the F7 thing and turned on Caret Browsing and it still doesn't work. The keys only works when I press Fn and then press up or down but is there any way to solve it for good?
