    Random BSOD on Dell laptop from 5 days


    I'm having an issue with my laptop, Dell Latitude E6420 where I keep getting random BSOD, mostly in every 3-4 hours. Sometimes the machine just freezes and needs restarting. I'm not sure what is causing the issues. Please find attached my DM Log Collector.
    Any help would be greatly appreciated.

    Thanks in advance

    Can you roll back the display driver to an earlier version that worked good there?

    Also, stress test the Graphics Card using Furmark. Take a screenshot of the furmark window before closing it. Upload the screenshot for us.

    Let us know the results.

    Nice!!

    Now observe how it goes with the other version of the display driver. Inform us for any further BSOD. :)

    You probably dont need this driver, as most of us dont. It is some bundled program of nvidia. Comes from the express install.
    Download the latest version of the display driver at first. Drivers - Download NVIDIA Drivers .... then follow this process....

    • Uninstall All nvidia items in Control Panel > Programs and features
      • 3D Vision Control Driver
      • 3D Vision Driver
      • Graphics Driver
      • HD Audio Driver
      • PhysX
      • nvidia Update
      • GeForce Experience

      (Are you using nvidia chipset drivers? If so, dont uninstall anything other than those are listed).
    • Now follow Drivers - Clean Left over Files after Uninstalling
    • Go to Drivers - Download NVIDIA Drivers, Download the latest WHQL (as you have done it already, skip this part). While installing, Select Custom (Advanced) install. In the next page, follow this settings:


    In short, dont install anything other than the display driver and the PhysX.

    Then give it a time. See how it goes. Let us know.
