Since it's a Laptop, try removing the battery pack and direct connect AC Adapter plug and check the difference. It might be a Battery Alarm set or you could try adjusting Power Options if certain features are available here

The thing that will cause a sound alarm would be the battery alarm(Low battery and Critical battery alarm) slider maybe up to max. instead of being atleast 5% and setting on alarm action is shutdown. How long after booting does the alarm sounds?

i start it up and it loads my desktop the fan kicks in as normal then it makes that loud noise and just shuts off

It's overheating...
With many laptops unfortunately the best way to properly clean them out is to let the shop handle it...

They have many tiny ill designed screws holding it all together....
