You can change how the system reacts on a BSOD, rather than close down immediately it can push out the BSOD information and leave the blue screen up. That way you can either record the data, the old fashioned way pen and paper ot take an image on your phone or camera.

In order for avast to analyse anything you have to send them the memory dumps created by the BSOD.

EDIT - NOTE: you shouldn’t piggy back on a topic that is:

  1. not know to be the same as yours.
  2. has already marked as Resolved.
  3. Finally thsi one isn’t down to avast as my update comment states.
