But it happened several time recently, I am doing nothing, just letting it on.  it suddenly crashed and let me search for  "driver_irql_not_less_or_equal (mwlu97w8x64.sys)". what does this mean?

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

    So I got really fed up with having this bluescreen error so I took my Surface pro 2 to the Microsoft store to see if any of their people could come up with a fix. They couldn't think of anything and were nice enough to exchange my old Surface Pro2 for a new one of the same model. This was done in the hope that a new machine wouldn't encounter these errors. Well I'm back to work with this new machine and this one is also blue screening and pointing at the same driver "mwlu97w8x64.sys". I'm not happy about this at all.

    I'm getting a replacement Surface Pro (first gen) today because of this issue.  Will report back but I am not optimistic.  The memory dumps point directly at this being driver/hardware issue.
