If you are a windows user you might be very well aware with the Blue Screen of Death (BSOD) scenario in which your computer tells you that your PC ran into some error and it will have to restart. From windows 8 to 10 this error is so common and you cannot find any individual who has not experienced it.

Over the years, thousands of users have reported this kind of error in their computer but Microsoft is doing nothing to resolve this issues and leave its users to find a solution for themselves. We know that feeling when the important files that you worked hours for are gone just because you have not saved them yet.

DPC_WATCHDOG_VIOLATION is one of those Blue Screen of Death issues. These errors are most irritating because you don’t have any option other than restarting your PC. The more the number of errors more frustrate a user becomes.

We have found a number of methods to fix this issue so you will not have to sit frustrated when your PC experience a BSOD.


This error generally comes with error code 0x00000133. DPC WATCHDOG VIOLATION is a common error when your SSD drive corrupts or its drivers are not updated to the latest version.

Microsoft website has some information regarding this error:

This bug check indicates that the DPC watchdog executed, either because it detected a single long-running deferred procedure call (DPC), or because the system spent a prolonged time at an interrupt request level (IRQL) of DISPATCH_LEVEL or above. The value of Parameter 1 indicates whether a single DPC exceeded a timeout, or whether the system cumulatively spent an extended period of time at IRQL DISPATCH_LEVEL or above.

In simple terms, it says that windows have stopped working because it is not getting responses from the hardware of the computer.

What are Causes of DPC_WATCHDOG_VIOLATION error?

There is no ultimate solution for the DPC_WATCHDOG_VIOLATION error because we don’t exactly know the reason behind the issue. So you may have to try multiple of the below solutions to get rid of the DPC_WATCHDOG_VIOLATION error.

Solution 1 – Fix the not properly connected cables

In some cases, DPC_WATCHDOG_VIOLATION occurs just because of the loose power and data cables.

If the cable had not properly connected and you fix the connection it is most likely that your error will be resolved.

However, if you don’t have any experience with CPU parts do not try this yourself and show it to the repair shop.

Solution 2 – Replacing iastor.sys driver with storahci.sys driver

iastor.sys driver is sometimes causing this error in windows 10 because it is not fully compatible in windows 10 yet. Microsoft suggests that you should replace iastor.sys driver with storahci.sys drive. Follow below steps to do the same:

  1. Open Device Manager by right clicking on windows button and selecting device manager.
  2. In the Device Manager window Select and Expand IDE ATA/ATAPI Controllers.
  3. Select controller which have SATA AHCI in its name(it will be like Standard SATA AHCI Controller). To verify that you have selected right controller, right click on the controller, select properties and move to the drivers tab, and then click on driver details. Check for the iastor.sys in the driver list, if it is listed there you are good to go.
  4. Again open the properties of the controller and click on update drivers.
  5. Select Browse my computer for driver software.
  6. Select Let me pick from a list of device drivers on my computer.


  7. Select Standard SATA AHCI Controller from the drivers’ list, if more than one driver is listed select which one is most recent.

Click Next, then Close and then restart your computer.

As we have stated earlier, the main reason for this error is the communication issues between hard disk and windows system software. Hence, it is likely that your Hard disk has some issue that causes the DOC WATCHDOG VIOLATION.

If your device has SSD, you have to update your SSD firmware if you have not already. Also, keep in mind that updating firmware means you can lose your data from the drive.

You can check a drive malfunctioning or corruption by command prompt commands, follow these steps to check for the corrupted disk in your device.

It also shows that which of your drivers are needed to upgrade and which drivers you don’t have but should have.

Also, many manufacturers have their own software which can detect required drivers just like Driver Easy. If that is available for your device manufacturer you can also use it to upgrade your drivers.
