If the errors are hardware related, the best thing to do is update the firmware of your components and the associated drivers. While not as common, software installations that affect your system software could also lead to DPC Watchdog Violations and the corresponding blue screen of death. For example, if your sound card driver does not support Windows 8, simply plugging in a set of headphones could produce a DPC Watchdog Violation error. Another likely cause is an outdated driver for one of your hardware components. One of the most common is an SSD drive that has old firmware not supported by Windows 8. Several things can cause a DPC Watchdog Violation to be triggered in Windows 8. This typically happens when the DPC is stuck at an interrupt request level (IRQL) of DISPATCH_LEVEL or above. DPC stands for "Deferred Procedure Call." The violation happens when the bug checker, called a "watchdog," detects a DPC that is running too long. While multiple stop codes can cause Windows to shut down, the most common is the "DPC Watchdog Violation." This error, often displayed as "DPC_WATCHDOG_VIOLATION," has a bug check value of 0x00000133, which may also appear in the error message. For example, if an unknown hardware device appears to pose a threat to your computer, it may trigger a "stop code," which will abruptly stop the current processes.
