May be TMJ.  You may be clenching your jaw when you're on the computer.  Try holding a pencil between your front teeth - not sideways, sticking out like a joint.  This prevents the jaw from clenching too much.  If it works, your dentist should be able to help, even if he just replaces the pencil with the proper device.
