What Causes DPC Watchdog Violation?

There are many causes of the DPC watchdog violation. These include outdated drivers, software & hardware incompatibility problems, unsupported firmware, and more.

To help you understand better, we’ve discussed the various causes in the paragraphs below.

Your System Has an Outdated, Damaged, or Wrongly Installed Driver

One of the most common reasons why you are seeing the BSOD error is because of outdated or damaged drivers. This means you have to update drivers manually or automatically with the help of third-party software.

Hardware Incompatibility

Software Conflict

If you install a program that is incompatible with the program already installed in your PC, you may encounter the BSOD error. For example, if you install a second antivirus program on your PC, there will be a software conflict, and this will lead to the BSOD error.

Outdated SSD Firmware

If your PC does not support the drivers or firmware of the hardware you are trying to connect to the system, you may also encounter the DPC watchdog violation error. If your PC is using an SSD, check to see if its firmware is up to date.

Corrupted System Files
