Hi Appraiser Genie,

I found you have posted the similar thread a few days ago, I suppose they are the same issue. As Ethan said, we need to collect the event logs and see if any related error is logged.

On the other hand, we have not received the related issue report about the updates of Windows 8.1 in Feb. Thus, I can't confirm this issue causes by these updates. I recommend you remove these updates to check if this issue still occurs.

If you have any update, please feel free let us know.

Regards,
