As I said, you may not be able to eliminate it. Read the links that I gave you, as they have some tips. But, usually you have to live with it. A forum member said his Alienware coil whine stopped when he disabled C-state control in BIOS. You could also disable Turbo Boost, which might make a difference, though you might not want to lose that processor boost. Settings | System | Power & Sleep | Additional power settings | select your plan | Change plan settings | Change advanced power settings | Processor power management | Maximum processor state: set to 99% or lower.If you set it to anything below 100%, Turbo Boost will not activate.
  Good day, My computer is making a high frequency chirping noise. It does not make this noise all the time but at random times. I'm not sure how to upload an audio recording to this form but I do have a recording of the sound. I have had my computer checked but no damage or failing components were found. Any suggestions? Thanks, Matthew
