Hence, you may want to know as to what “DPC Watchdog Violation” error message really means and why it occurs in Windows computers.
What is DPC Watchdog Violation Error?
According to Microsoft, DPC_WATCHDOG_VIOLATION Error indicates that a DPC watchdog bug test was triggered on your computer, either due to a single long-running deferred procedure call (DPC), or because the system spent a prolonged time at an interrupt request level (IRQL) of DISPATCH_LEVEL.
