:wink:

when I run an Avast full scan,after 15 minutes or more of initiated, the system crashes with the typical blue screen... There´s any fix for this?

From the software side, BSOD appears at the driver level. What causes it I don’t know but we can check.

Download BlueScreenWiew tool from here:
http://www.nirsoft.net/utils/bluescreenview.zip

Double click on BlueScreenView.exe file to run the program.
When scanning is done, go Edit>Select All.
Go File>Save Selected Items, and save the report as BSOD.txt.

Attach BSOD.txt here.
