I turned on my laptop this morning (my other machine)and whenever I tried to type anything in ie web addresses or passwords I am getting a string of 'j's (ie jjjjjjjjjj) The J itself doesn't seem to work when the key is depressed. The laptop itself is also intermittently 'ringing' Could this be a motherboard problem? The laptop itself is approx six or seven years old. Any ideas? Thanks in advance.
