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

    Hello allenyw80,

    Have you tried going through your listed devices in Device Manager and seeing if any listed there have an exclamation point, meaning that it requires attention?  Do this:

    • Open Desktop
    • Swipe from right and choose Settings
    • Click on Control Panel
    • Open Device Manager

    Go through the listed devices here and see if any requires attention. If so, open that device's listing, click on the Driver tab, and choose to uninstall, NOT delete, the driver. 

    Please let us know what you find.

    Best Wishes,

    Zack_T

    I've tried almost everything and this still happens using my university network. This is becoming incredibly frustrating.

    The IT department at my university will not look at personal devices. The blue screen error is specifically calling out the Marvell drivers. I'm having the same problem as everyone else in this thread. A quick internet search yields multiple threads involving this same error. Has anyone out there found any solutions?

    Daniel,

    Asking questions allows to isolate the problem. The same symptoms might not mean the same causes. Plus each user is using the device in a specific environment.

    Cheers,
