Almost all the time, even when not actively using my laptop the fan on the left starts and stop about ever three seconds. It bugs my wife so much I can not work in the same room as her, and I admit it bugs me to more and more. Any ideas how I might fix this, eg in the BIOs, or? I have changed the Windows cooling properties with no effect. I have also killed all the Startup processes, with no change. In fact, it does it when starting up, before windows runs, even after a full windows shutdown.
