Dell Vostro 3405 Sudden Shutdown especially when in MS Teams call

Hi All,

We are seeking help on our problem regarding Dell Vostro 3405 sudden shutdown, especially when in MS Teams call and someone is sharing their screen. 

So what happens more often is when we are in an MS Teams call a meeting and someone shares their screen, the laptop suddenly shuts down without any warning. Sometimes while we are in an MS Teams call for a long time and even though no one is sharing the screen, it will suddenly shut down. And the most unexpected thing here is the random sudden shutdown of the laptop that happens maybe twice a month.

I have attached screenshots of the Event Viewer logs whenever we experienced the problem. I hope you can help us with our problem. Thank you!
