Unexpectedly Shutdown in Windows 10

[Anu_007]

Hi,

Since last few weeks i am facing issues with my notebook. This notebook is pretty old, bought in 2016.

After working for say 15-20 minutes, laptop shutdown unexpectedly. No errors message pops up next time it starts.

I thought this might be due to some updates hence i re-installed fresh windows but again auto shutdown happens.

I have already replaced my battery 6 months back and it was working fine till last few weeks. Not sure if is this due to increase in temperature of my notebook. I installed an app to monitor the temperature profile and it was fluctuating between 40-51 C.  

Thanks.
