Check your action (distance between strings and frets) isnt too low. You can adjust that by turning the little screws in the saddles (clockwise to raise the aciton, anti-clockwise to lower it).
Make sure your saddles at the bottom arent worn. They probably wont be but its always good to check them.
If you're keeping the guitar on a stand, make sure its not near a radiator. This dries the wood out and causes it to warp. If so, ask someone at a local guitar shop to help you straighten the neck.
