What is DPC Watchdog Violation?

The “DPC Watchdog Violation” is an error that indicates your system ran into a problem it couldn’t handle, leading to a crash and the infamous Blue Screen of Death (BSOD). “DPC” stands for “Deferred Procedure Call,” while “Watchdog” refers to the bug checker, which regularly monitors or “watches” your PC’s performance.

What Causes The DPC Watchdog Violation Error?

This issue can occur in conjunction with other BSODs, and they all have a common cause. If you go to the official Microsoft page, you may learn more about this problem:

This bug check shows that the DPC watchdog was activated, either because it detected a single long-running deferred procedure called (DPC) or because the system was at an interrupt request level (IRQL) of DISPATCH LEVEL or higher for an extended period of time.

The value of Parameter 1 indicates if a single DPC exceeded a timeout or whether the system spent an extended length of time at or above IRQL DISPATCH LEVEL. Windows 10 has ceased running, according to Microsoft, because it was unable to receive a response from a hardware component, its driver, or a software programme associated to it.

The most common hardware component in question is a disc drive, which causes Windows to crash when the disc becomes unreadable (similar to removing the HDD’s data cord while it’s in use).

In other circumstances, the issue is caused by hardware incompatibility, an outdated BIOS or UEFI, SSD difficulties, improper overclocking, or even a malware infection.

Understanding what leads to this error can help in resolving it swiftly. Here are some common causes:

  • Driver Issues: Outdated or incompatible drivers, especially the SSD driver, can lead to this error.
  • Hardware Incompatibility: Using old or failing hardware components can trigger the violation.
  • Software Conflicts: Occasionally, certain software might not be compatible with Windows, leading to this error.
  • Overloaded System: An exceedingly high system load can sometimes cause the DPC Watchdog Violation.
