    Your Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet Controller is causing issues. The driver needs updating, update it here.

    Uninstall DaemonTools, a known cause of BSODs.

    1. Uninstall Daemon Tools.
    2. Download the SPTD standalone installer and follow these steps:
    3. Double click the executable to open it
    4. Click the button shown below

    If the button it is grayed out, as shown in the image, there is no more SPTD installation on your system, and you can just close the window.
