I got my iMac about 2 weeks ago and everything's been fine until now. My "n" key on my keyboard is playing up, I can type 1 "n", but if i type something like CNN , then I get CNNNNNNNNN, sometimes the "n's" go on for longer than that. Only the "n" key does it. Its also staring to type the "n" key randomly anywhere. Please help, I've work to be done. Its the standard wired aluminium keyboard that comes with the computer. I've tried rebooting, unplugging the keyboard and more and nothing works. eg. My n nkey is not nnnnnnnnnnnnnfunnnnnnnnnnnctioning nproperly. (I didnt type nthat purposely, its doing all those "N's" by itself.
