How to fix 'DPC WATCHDOG VIOLATION' error?

When encountering a blue screen error of "DPC WATCHDOG VIOLATION", 1. First update or roll back the driver, especially graphics card, network card and motherboard driver, you can use the device manager or manufacturer tools; 2. Disable or uninstall third-party antivirus software and use Windows Defender instead; 3. Check the storage device and driver, update the SSD firmware or replace the AHCI driver; 4. Disable the Core Isolation function to eliminate system settings conflicts, and in most cases, try these methods in order to solve the problem.

An error of "DPC WATCHDOG VIOLATION" is encountered, usually a blue screen error triggered by the Windows system when it detects a delayed delay procedure call (DPC) that is too long. This problem is mostly related to hardware drivers or system settings. Here are some practical solutions.

1. Update or rollback the driver

The most common cause of this problem is that the driver is incompatible or there are bugs. Especially graphics cards, network cards and motherboard drivers are most likely to cause such problems.

• Go to Device Manager and find common hardware devices such as "Display Adapter", "Network Adapter"
• Right-click and select "Update Driver"
• If you have recently updated the driver, you can try "rollback the driver" to the previous version

You can also use driver management tools provided by the manufacturer's official website (such as NVIDIA GeForce Experience, Intel drivers and support assistants, etc.) to automatically update.

2. Disable or uninstall third-party antivirus software

Some third-party antivirus software (such as Kaspersky, Bitdefender, etc.) may interfere with the system's DPC mechanism when running in the background, resulting in a blue screen.

• Try temporarily disabling or completely uninstalling the antivirus software
• Use the system's own "Windows Defender" instead
• After uninstalling, restart the computer and see if there are any problems

Some users reported that the problem disappeared immediately after uninstallation, indicating that the intervention of such software on the underlying system may indeed cause compatibility issues.

3. Check storage devices and drivers

If you are using an SSD, especially an SSD of non-mainstream brands or older models, it may also be a storage driver or firmware issue.

• Go to Device Manager to see if the "Disk Drive" has a yellow exclamation mark
• Update or rollback related drivers
• Check whether there is firmware update on the official website of the SSD manufacturer
• Check hard drive health status using CrystalDiskInfo

Sometimes there is a problem with the AHCI driver installed by default in the system. You can try manually replacing it with Microsoft's basic AHCI driver to see if there is any improvement.

4. Disable Core Isolation

The "Core Isolation" feature in Windows 10/11 can sometimes cause DPC issues, especially when conflicting with certain drivers or software.

• Open Settings > Privacy and Security > Windows Security Center
• Go to the "Device Security" or "Core Isolation" settings
• Temporarily turn off the "Memory Integrity" or "Core Isolation" function
• After restarting, see if there is still a blue screen

Although this feature helps with security protection, it is indeed easy to cause compatibility issues in some configurations.

Basically these common treatments. You can try it in order, starting with driver updates and antivirus software, and then check the storage device and system settings in depth. In most cases, the problem can be solved.
