DPC Watchdog Violation 133 is a stop error that may appear on Windows Server 2012 or 2012 R2 servers when too much time is spent in DPC routines.
The most common cause of this error is corrupt or outdated drivers. But it can also be due to incompatible hardware devices or conflicted software programs.
Causes
The DPC watchdog timer is a Microsoft feature that enables the system to stop running in order to identify faulty drivers. If it detects that too much time has been spent in DPC routines, it will generate an error (dpc_watchdog_violation 133). This could be caused by either an inadequate driver, incompatible hardware, or software conflict.
The most common cause of blue screen errors is outdated device drivers or improper installation. To resolve the issue, download the most up-to-date versions of all your device drivers and make sure they are fully compatible with Windows 10. Doing so will guarantee your computer runs optimally. Alternatively, disconnecting external devices may help identify where the issue lies; if so, updating device drivers or replacing the device may resolve it permanently.
Solution 1: Restart
One of the quickest and most reliable solutions to resolve this error is simply restarting your computer. This can be accomplished either by booting into Safe Mode or shutting down and restarting it. Be sure to do it in the proper order; if there are any other programs or software installed, they may need to be uninstalled first in order to avoid conflicts during this process.
Another option to fix this problem is running a disk check using the Windows Disk Cleanup program. This will identify any bad sectors on your hard drive and allow you to reclaim them. However, please be aware that this solution may take some time, especially for some users. If the error persists after running this solution, it could be due to driver issues.
Solution 2: Disable FreeSync
The DPC watchdog timer is a Windows feature that automatically shuts down the system if it spends too long running DPC routines. Additionally, this helps identify drivers which are misbehaving or stuck in deadlock scenarios. Microsoft added this feature to both Windows Server 2012 and 2012.
This stop error may be due to FreeSync, but it could also be related to an out of date driver or issues in other programs. As a first step, try disabling FreeSync in the AMD graphics card driver and see if that helps resolve the problem.
To resolve the problem, open your computer’s control panel and open AMD’s control center. Under Display settings, click Graphics settings. Now select AMD graphics preference and save. This should resolve your issue; if not, try the next solution.
Solution 3: Reinstall
The dpc_watchdog_mizzurd ntkrnlmp.exe blue screen of death (BSOD) can be quite frustrating. Thankfully, there are several solutions that don’t require turning your PC into a zombie: some easy enough for anyone to implement while others require more specialized knowledge and equipment. For example, installing a Microsoft hotfix may resolve the BSOD error message associated with it; performing a disk check on your hard drive could also provide helpful insight into any drivers that need updating; using this information you can identify any outdated drivers too!
Alternatively, you can try disconnecting and reinstalling all external devices to see if that solves the issue. This is usually the best method for identifying which driver or device is causing a BSOD.
