Hi allenyw80,

Thank you for the reply. I understand you are having the same issue on your replacement device and I know this is a frustrating situation for you. I'm here to guide you in the right direction. 

Please try the following:

  1. Back up your files.
  2. Do a reset.
  3. Go to Charms>Settings>PC settings>One Drive>Sync Settings>Turn off Sync your settings on this PC. This step will isolate the settings from other computers that might affect your Pro 2.
  4. Install all updates.
  5. Install your apps back one by one to see if the problem comes back with certain apps.
  6. If the problem continues, please contact our Support.

Best Regards,

Clare

    Greetings AvivS,

    How many times have you gotten the error? Can you recall when you first started to experience it?

    Yes, blue screen.

    I was just opening a web page, nothing special before that.

    I had a few crashes earlier in the week related to Toshiba dynadock and I reinstalled the DisplayLink driver, and no crash since then when connected to dynadock.

    The blue screen happened when I was not connected, just wifi.

    Thanks, Aviv.
