Hi,

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 Another likely cause is an outdated driver for one of your hardware components.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.

Now coming back on how to fix DPC Watchdog Violations:

If the errors are hardware related, the best thing to do is update the firmware of your components and the associated drivers.

Firmware and driver updates are usually available in either the Support or Downloads section of most hardware manufacturers websites.

If the errors are software related, you can either reinstall the program(s) you may think may have started producing the errors or use Windows "System Restore" function to fix potential system software issues.

If you have tried the above options and you still are experiencing DPC Watchdog Violation errors, you can use "Action Center," a control panel available in both Windows 7 and Windows 8.
This panel displays important system messages and provides recommendations on how to resolve problems.

If you still have errors after using Action Center, they may be caused by faulty hardware.
If this is the case, you may need to have your PC examined by a technician who can diagnose what component needs to be replaced.

I hope this helps.

Thanks,
Lokesh.
