What causes DPC Watchdog Violations?

Several things can cause a DPC Watchdog Violation to be triggered in Windows 8. One of the most common is an SSD drive that has old firmware not supported by Windows 8. Another likely cause is an outdated driver for one of your hardware components. 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. 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.
