​What is a ​DPC Watchdog Violation error?

A DPC Watchdog Violation is an error occurring in your Windows system. DPC is the abbreviated form for Deferred Procedure Call. Watchdog denotes Bug Checker, which helps monitor all windows processes and the background performances. Its check value is about 0x00000133.

The violation message appears when it waits longer than usual such as over 100 microseconds. It will show the error message if it does not find a response.

​Why Do I Keep Getting Dpc Watchdog Violation? What Causes It?

Several factors can cause the dpc watchdog violation error message. Here are the factors that lead to a DPC Watchdog error in Windows 10:

  • The blank blue screen error, also known as BSOD error (Blue Screen of Death), is due to hardware incompatibility in your PC or laptop. You will find the popup screen when you attempt to connect incompatible hardware such as an AMD Graphic card, NVIDIA, or even an external drive.
  • If the firmware or driver of the hardware you are connecting to your device is not supported by your device, you will find the BSOD popping up. This can happen when you connect the external hardware for the first time or even when you connect hardware after a couple of months.
  • The conflict between two software applications can also cause a violation error. If the software you are installing in your device is incompatible with software present in your device already, it can cause the DPC watchdog violation blue screen error. You can find the details for this in the device manager.
  • Corrupt system files may also contribute to this issue. Your system files may get corrupted for several reasons, but malware infection is the most common.

As you can see, the factors behind the bug trigger are plenty. You can face the issue while updating your Computer or installing software, which can also occur randomly.

DPC Watchdog errors can be caused when the system needs to refresh all its hardware drivers. It may also occur when your drive has files that your present Windows 10 version does not support.

How to Fix DPC Watchdog Violation Error

Step 3:

This process may take some time to complete when you do this for the first time. However, when you restart your Computer, verifying the files and identifying the corrupted ones will be easy.

Fix ​5: Check Software and Hardware Compatibility

While you may expect an external device to work smoothly right from the time you start using it, this is not. You may face a violation error, and the drive may not be compatible with the hardware or software present in your device. Here is a simple way to resolve this issue.

Hardware Compatibility – If you are using multiple devices, you must plug in the device one by one and check their compatibility to identify the driver causing the error.

When you identify the particular device, you can check its specs, find out about compatibility with your system, and exchange it for another compatible device.

Software Compatibility – For software conflicts causing the violation error, you use the trial and error method as in the hardware compatibility testing. Once you identify the software, uninstall and restart your system to determine if the error persists. If this does not work out, follow the steps below:

Step 1:

Press Windows Key and R buttons simultaneously after opening the Windows Run feature.

Step 2:

Go to ‘Control Panel’ by entering it in the dialog box, and press ‘Enter.’

Step 3:

Choose Uninstall a Program option from the control panel

programs and features

Step 4:

In the applications list, under the ‘Uninstall a Program’ feature, find the software you had installed earlier by checking the installation date and time present on the top portion of the table.

Step 5:

You can uninstall the programs that you suspect are causing the issue from the time and date in which they were installed.

Step 6:
