​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. This helps monitor all windows processes as well as the background performances. Its check value is about 0x00000133.

The violation message appears when it waits for a longer duration than normal such as over 100 microseconds. If it 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 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. 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 blue screen error. You can find the details for this in the device manager.
  • Corrupt system files may also contribute to this issue. You system files may get corrupted due to several reasons but the most common one is malware infection.

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.
