Imagine working in the office or working from home on your device and suddenly your screen goes blue, with a message that says “DPC Watchdog Violation”. Now what? The issue does not go away on its own. There are many reasons due to which such an issue can arise. The error also can come on the screen multiple times.

As we said, it appears on the BSOD (Blue Screen of Death). Moreover, there is no accurate prediction that at what time it will occur. If you do not know about dpc watchdog violation and what are the ways to solve this issue, then do not worry, as we in this article, are going to discuss ways to solve this dpc watchdog violation.

What Is a DPC Watchdog Violation?

First of all, dpc is abbreviated as “deferred procedure call”. When a deferred procedure call is detected by the DPC Watchdog timer that is running after the already determined time, this issue arises. With the help of this mechanism, tasks that have higher priority can delay the execution of tasks that have lower priority. Hence, the issue arises when a task runs beyond the time limit.

Certain times, the issue comes in a loop. Every time the issue occurs you try to restart the device but the issue again comes up and this goes on back and forth. In this type of circumstance, you need to access your device in safe mode. After you have successfully accessed Windows 10 in safe mode, you can proceed to look at what has caused the issue and in turn resolve the query.

When Can This Violation Occur?

DPC Watchdog Violation error can almost occur at any time. But yes, there are certain occasions where the probability of this issue popping up is high. Following are some of those occasions:

  • The error can occur just after you have booted the device. If it does, then there are high chances that the issue is due to a hardware fault.
  • If the error is due to a network card driver, then the error will pop up after you have made a connection with the internet.
  • Even if you try to install Windows 10, the issue might arise.

Apart from the above-mentioned occasions, the issue can arise at any instance. Now we have known when the issue can arise, let us also examine the causes.

What Causes It?

Remove External Device (If Any)

As we said, at certain times, a hardware conflict might be the reason behind this trouble. If you have recently installed a fresh device driver such as a printer, scanner, external hard drive, etc., and faced this issue, try removing them to see if the issue persists or not. If it does, move on to the next set of solutions.

You can make use of certain third-party tools to solve this issue. Third-party tools can help you to solve some of the blue screen errors. If a need arises for creating a restore point, these third-party tools can help you in doing that as well. After successful installation of the software, run it. It will automatically identify (in most cases) the issue and will try to resolve it on its own. However, not all third-party tools are free. You need to upgrade from the basic plan to get full services.
