What is the DPC Watchdog Violation Error?
The Deferred Procedure Call (DPC) is a Windows feature that takes care of interruptions in the Operating System (OS). The main function of the DPC is to permit a task to start on your computer but it is not executed, because of a request from the highly prioritized interrupt request level (IRQL).
The DPC lets the needed driver organize the Interrupt Service Routine (ISR) fast, as it refers to the process of the lower-level IRQL codes being executed.
The Watchdog is a bug checker which helps supervise both the background and foreground processes on your computer.
The DPC Watchdog Violation error occurs when Watchdog has to wait for over 100 microseconds(ms) without a response. The error message comes up in the form of a Blue Screen of Death if there is no response from the bug checker.

These are the procedures that can help you fix the DPC_WATCHDOG_VIOLATION error.
1. Disconnect External Devices attached to the Computer
The presence of devices like printers, external storage devices, HDMI cables, and game controllers in the ports of the computer is one of the reasons why the DPC Watchdog violation error occurs on your computer.

If you wish to know which device was responsible you can connect them one after another and see which causes the issue.
Sometimes, the cables on your device may not be connected properly and the DPC Watchdog Violation can come up. If the disk cables are loose, there is a likelihood that the disk goes undetected by the computer, causing it to crash and throw this error at you. Make sure every cable is connected correctly to avoid such errors.
If this does not work, we recommend keeping the devices disconnected while you try out the other fixes to rectify this error.
