My Dell laptop started making a loud buzzing sound all of a sudden. For context the laptop is around 4 years old now, i have stopped using it for almost a year now, its just sitting on my table for a looong time and nobody at home is using it. Today i tried to open it as i had to attend an online exam, i opened the application to attend the exam and that is when this loud buzzing sound started. I tried to shut it down multiple times but the buzzing sound isnt stopping. Please help is there something i can do to stop it
