DPC_WATCHDOG_VIOLATION Blue Screen in Windows 10

Some Windows 10 users have been reporting that they occasionally receive a DPC_WATCHDOG_VIOLATION Blue Screen, with a Bug Check code of 0x00000133, when working on their computer.

Apparently, this issue occurs because the iastor.sys driver, is not compatible with Windows 10. Microsoft is aware of this problem and is currently investigating ways to solve this issue, by preventing the driver from being migrated when upgrading to Windows 10.

Select the controller with SATA AHCI in its name. 

To verify that you’ve selected the right controller, right-click the controller, select Properties, click the Driver tab, and then Driver Details. Verify that iastor.sys is a listed driver, and click OK.

Now, from the Driver tab, select Update Driver. Next, select Browse my computer for driver software.

Select Let me pick from a list of device drivers on my computer, and then finally select Standard SATA AHCI Controller.

Click on Next and follow the procedure to install the driver.

Restart your Windows 10 computer.
