What is a DPC Watchdog Violation error?
A DPC Watchdog Violation is a type of error occurring in your Windows system. DPC is the abbreviated form for Deferred Procedure Call. Watchdog denotes Bug Checker.
The Bug Checker helps monitor all windows processes as well as the background performances. Its check value is about 0x00000133.
The violation message appears when the Bug Checker waits for a longer duration than normal such as over 100 microseconds. If the Bug Checker does not find a response, it will show the error message.
Why Do I Keep Getting Dpc Watchdog Violation? What Causes It?
The violation error message can be caused by several factors. Here are the factors that lead to a DPC Watchdog error:
- The blank blue screen also known as BSOD (Blue Screen of Death) is due to hardware incompatibility in your PC or laptop. When you attempt to connect incompatible hardware such as an AMD Graphic card or NVIDIA or even an external drive, you will find the popup screen.
- If the firmware or driver of 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. You can find the details for this in the device manager.
As you can see, the factors behind the bug trigger are aplenty. You can face the issue while updating software on your computer or after having installed software. It 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.
Fix 1: Change SATA AHCI controller

Hardware Compatibility –If you are using multiple devices, you have to plug in the device one by one and check their compatibility to identify the drive that is causing the error.
When you identify the particular device you can check its specs and 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 it and restart your system to find out if the error persists. If this does not work out, follow the steps below:
