If you encounter the DPC Watchdog Violation error or error in Windows 10, here are the steps you can take to fix it.
Windows errors come and go and DPC Watchdog Violation is certainly one of them. If you’re experiencing the DPC Watchdog Violation error, here’s how to fix it.
What is DPC Watchdog Violation Error
The DPC Watchdog Violation error stems from a system hardware problem and tells you that Windows cannot communicate with the hardware properly.
When Windows 10 was first introduced back in 2015, there were many DPC Watchdog Violation errors related to solid-state drives (SSDs), such as out of date SSD firmware, old SSD driver versions, or hardware incompatibility issues. The problem is that SSD manufacturers haven’t developed and released updated drivers for the new operating system, causing a number of issues, including the DPC Watchdog Violation error.
DPC stands for deferred procedure call, a system-level process (which means it’s happening in the background). A DPC basically spells out when a piece of hardware wants to communicate with the CPU but does it a bit off-the-shelf. If the DPC does not complete within a certain timeframe, it causes a DPC Watchdog Violation error (where Supervisor is the process that ensures the DPC completes within the specified time).
Deferred procedure calls work alongside “system interrupts,” which are other system-level processes. Whenever software or hardware wants to do something, it “interrupts” the CPU to tell it what is going on. If the system spends too long at the interrupt request level (IRQL), it can also cause blue screen errors.
How To Fix DPC Watchdog Violation Error
Usually, DPC Watchdog Violation Error is solved by updating the driver and system, and checking your hardware properly. That check might mean reinstalling and cleaning your hardware, as well as using a third-party tool to check the hardware isn’t failing mechanically.
Check And Reinstall Your System Hardware
The first thing to do is to check your system hardware for anything that looks out of place. That could mean loose cables, a misplaced drive, misplaced RAM, or anything in between. The following video explains how to reassemble your hardware and check that everything is secure:
Clean Your Computer
When your computer case is open, you should clean your hardware. Not with soap and sponges, of course! Instead, you should give your fan a blast with compressed air and complete some general PC maintenance steps. Remember, your PC is like any other piece of hardware you own. Take care of it and it will last longer.
System Health Check
Once installed, you can open various tabs and dropdown menus to check drive health, operating temperature, voltage, and more. If any of your hardware shows a large number of errors or is operating at extreme temperatures, you should consider finding out what is wrong with the component or having it replaced entirely.
Run SFC And CHKDSK
Another fix for the DPC Watchdog Violation error is to run the integrated Windows System File Check (SFC), a system tool that scans your drive and fixes errors.
Before running the SFC command, it is important to check if it is working properly. To do this, we use the Deployment Image Servicing and Management tool, or DISM.
Perform the following steps.
- Type command prompt (Admin) in the Start menu search bar, then right click and select Run as administrator to open an elevated Command Prompt.
- Type the following command and press Enter: DISM /online /cleanup-image /restorehealth
- Wait for the command to finish. The process can take up to 20 minutes, depending on the health of your system. The process seems to crash at times, but wait for it to finish.
- When the process is complete, type sfc /scannow and press Enter.
- Type command prompt in your Start menu search bar, then right-click the most suitable one and select Run as administrator. (Or, press the Button Windows + X, then select Command Prompt (Admin) from the menu.)
- Next, type chkdsk /r and press Enter. The command will scan your system for errors and fix any issues along the way.
Update Your SSD Driver
In general, Windows 10 takes care of updating your drivers. Updates are also automatic in Windows 10, so you shouldn’t lag too far behind the update cycle. That said, things do slip off the net, and drivers can become corrupted for one reason or another.
To check for your latest automatic driver updates, go to Update & Security > Windows Update > View update history. The latest driver updates appear here.
Now, type device manager in the Start Menu search bar and select Best Match. Open section Disk drives, then right click the driver for your SSD and select Update drivers. choose Search automatically for updated driver software to have Windows automate the update process for you.
Update Windows 10
Another fix is to check if Windows 10 has any pending updates. open Update & Security > Windows Update. If there is an update available, download and install it.
Remove Software (Software)
Does the DPC Watchdog Violation error start after installing new software? If so, you should uninstall the software, reboot your system, and check if the image persists.
insert programs in your Start Menu search bar and select Best Match. Switch the Sort by drop-down menu to Install date, sort the list of programs by install date. Remove all recently installed programs, then reboot your system. If the DPC Watchdog Violation error disappeared, you’ve found the culprit.
DPC Watchdog Violation Repairable
Like many other Windows 10 blue screen errors, the PC Watchdog Violation error is an irritant. But in the end, if you follow the steps in this list, you can fix PC Watchdog Violation error without causing too much stress.
