Description

The first BSOD (0x00000139) occured this year January 2 and never happened before.

After core dump analysis I came to conclusion that this error happens because because of a network adapter.

January 4 after a BSOD during the night I tried to manually reproduce this error.

Experimentally, I found out the moment the error occurs - Computer maintenance Screnshot 3.

Error dates can be found on Screenshot 1.
