In some cases, incompatible hardware with your operating system can be the cause as well. For example, if you haven’t installed the video card driver for your new operating system, DPC Watchdog Violation could easily happen when you try to watch a video online. In most cases, you will see this error when your device driver(s) is outdated or installed wrongly. Why would I have the DPC Watchdog Violation error? Probably because a DPC is running too long a time, or your system is stuck at an interrupt request level (IRQL) of DISPATCH_LEVEL or above. When you see the Violation message, your PC watchdog (aka bug checker) is overwhelmed. Watchdog refers to the bug checker, which usually monitors or track your Windows programs and your PC performance. The DPC Watchdog Violation blue screen of death bug check has a value of 0x00000133. If you can’t log into Windows, power on and off your PC 3 times to perform a hard reboot and restart it in Safe Mode, then try these solutions. You’ll need to be logged into Windows on the problem computer to try any of these solutions.
