DPC_WATCHDOG_VIOLATION Blue screen error is mainly caused by driver or hardware problems, especially third-party drivers are incompatible. 1. Check and roll back or uninstall the recently updated drivers, and give priority to using the official driver; 2. Update or reset the storage controller driver, check the RAID/AHCI mode settings in BIOS/UEFI; 3. Turn off third-party antivirus software or system tools to eliminate interference; 4. Run memory and disk detection tools to troubleshoot hardware problems; 5. If it still cannot be solved, you can analyze the cause of further positioning of the blue screen log file.

DPC_WATCHDOG_VIOLATION is one of the common blue screen errors in Windows 11 and usually occurs when the system detects that the delayed procedure call (DPC) has been executed for too long. This problem is mostly related to drivers or hardware, especially third-party driver compatibility issues. Although it looks scary, it can be troubleshooted and fixed in most cases.

Check for recently installed drivers

The most common cause of this error is incompatible or problematic drivers. Especially if you have recently updated the driver of a device, such as a graphics card, network card or sound card, it is likely that it is causing it.

• Rollback the driver version : Open "Device Manager" and find the device you suspect is in trouble. Right-click "Properties" → "Driver" tab → click "Rollback Driver".
• Uninstall the latest updated driver : If you cannot determine which driver is causing the problem, you can try uninstalling several recently updated drivers and observe whether there is still a blue screen after restarting.
• Use the official driver : Try to download and install the driver from the official website of the device, rather than relying on general drivers that automatically update Windows.

Some users have reported that specific brands such as Realtek network cards and NVIDIA graphics cards are prone to trigger this error in certain versions, and pay special attention to the driver status of these devices.

Update or reset the storage controller driver

DPC_WATCHDOG_VIOLATION is sometimes associated with storage controllers, especially when using NVMe SSDs.

• Open Device Manager → Expand the Storage Controller section.
• Right-click on each listed device and select "Update Driver".
• If the update cannot be found, you can also try "Uninstall the device", then restart the computer, and let the system reinstall the default driver.

Also, if you are using RAID or AHCI mode, you can check if the current settings match the operating system in the BIOS/UEFI settings. Inconsistent modes may cause abnormal hard disk communication, causing blue screens.

Close or suspend third-party antivirus software or system tools

Some security software (such as antivirus software, firewalls, optimization tools) may interfere with the underlying system operations, causing DPC to time out.

• Try temporarily disabling or completely uninstalling the third-party security software you are using.
• After restarting the computer, see if there will be a blue screen.
• If the problem disappears, it means it is a problem caused by the software. You can consider replacing it with a more stable alternative, or wait for the manufacturer to release a fix patch.

Defender, which comes with Windows, is generally relatively stable, and it is recommended to use it first during the troubleshooting period to eliminate third-party interference.

Check for hardware problems

Although it is not as common as the driver problem, memory instability, hard disk bad tracks and other problems may also indirectly lead to DPC_WATCHDOG_VIOLATION.

• Run the Windows Memory Diagnostic Tool: Press Win R, enter mdsched.exe , select Reboot now and check memory.
• Run chkdsk /f /r using the command prompt to scan and fix disk errors.
• If you have additional hardware devices (such as external hard drives, USB expansion cards), try unplugging them and checking them one by one.

This type of problem is relatively rare, but it is difficult to locate once it occurs, so it is best to check the hardware in depth after confirming that the driver is correct.

Basically these commonly used methods. In most cases, DPC_WATCHDOG_VIOLATION is caused by driver conflicts or incompatibility, and the focus is on troubleshooting recent changes one by one. If the problem still exists, you can try to view the blue screen log (.dmp file) for more clues, but that requires a certain technical foundation.
