I have a Dell Inspiron 6000 that is just over 2 years old. Just a few weeks ago the l and ; keys became super sensitive so that now if i even graze them this happens: llllllllllllllllllllllllllllllllllll or ;;;;;;;;;;;;;;;;;;;;;;;;;. And it's only those two keys that do that. Does anyone have any idea how to fix this? Thanks!

You may have something underneath them. With the laptop off, turn it upside down and use a new soft paintbrush carefully between the keys to shift anything that might be there.
Golden rule - no food or drink near keyboards!
