@ayashasaeed it should be a moving part that gets louder. Teh passives on the motherboards would not do this. I suspect you are having cooling issues and the noise may actually be a fan failing. WE will never know until you open up your computer and do a deep-dive. Use this HP EliteBook 820 G3 Maintenance And Service Guide to work on your computer. Once you have a better view, post some good pictures of the fans, heatsink etc. with your Question. That way we can see what you see and hopefully find a permanent solution

Usually, sparking sounds are not a good thing. Is this with the powersupply connected or just the battery?
