Windows errors come and go … and the DPC watchdog violation is certainly one of them. If you encounter the DPC Watchdog Violation error, here are some ways to fix it.
What is the error when violating the DPC watchdog?
The DPC Watchdog Violation error is due to problems with the system hardware and indicates that Windows was unable to communicate properly with the hardware.
When Windows 10 was introduced in 2015, there were a variety of DPC Watchdog Violation errors related to solid state drives (SSDs), such as outdated SSD firmware, old SSD driver versions, or hardware incompatibility issues. The problem was that SSD manufacturers hadn't developed and released updated drivers for the new operating system, which led to a number of issues including the DPC Watchdog Violation bug.
DPC stands for Calling the delayed procedure, a system-level process (ie it takes place in the background). A DPC essentially indicates when a piece of hardware wants to communicate with the CPU, but this is a little out of sequence. If the DPC does not resolve for a certain period of time, it will cause a "DPC Watchdog Violation" error (where the watchdog is a process that ensures that the DPC is resolved within the allotted time).
Deferred procedure calls work alongside "system interrupts", another process at the system level. Whenever software or hardware wants to do something, it "interrupts" the CPU to let it know what is going on. If the system spends too long at Interrupt Request Level (IRQL), blue screen errors can also occur.
How to Fix DPC Watchdog Violation Error
Typically, driver and system updates will fix a DPC watchdog violation so your hardware gets a good scan. This check can mean reinserting and cleaning your hardware, as well as using third-party tools to verify that the hardware is not failing mechanically.
1. Check and reseat the system hardware
The first thing to do is check your system hardware for anything that looks out of place. That could mean a loose cable, a misplaced drive, unused RAM, or anything else in between. The following video explains how to reinstall your hardware and verify that everything is secure:
Clean your computer
While you have your computer case open, you should clean your hardware. Of course not with soap and a sponge! Instead, you should apply compressed air to your fans and perform some general PC maintenance steps. Remember, your PC is like any other piece of hardware you own. Take care of it and it will take longer.
2. System Health Check
After physically cleaning your system, you should perform a system health check. A system health check uses third-party tools to determine if hardware bits are about to fail. There are tons of Windows PC health tools out there, but one of the easiest tools to use is Speccy. Speccy displays a variety of PC health indicators in a single program, making it a great benchmarking tool.
Once installed, you can open the various tabs and drop-down menus to check the drive's health, operating temperatures, voltages, and more. If any of your hardware has a high number of failures or operates in extreme temperatures, consider finding out what is wrong with the component or replacing it entirely.
If Speccy has any issues with your SSD, there is always room for further investigation. Check out the main warning signs that your SSD is about to fail and fail.
3. Run SFC and CHKDSK
Another update for the DPC Watchdog Violation error is running the built-in Windows System File Check (SFC), a system tool that will scan your drive and fix errors.
Before you run the SFC command, you need to check that it is working properly. For this purpose we use the Deployment Image Servicing and Management tool or DISM.
Like SFC, DISM is a built-in Windows utility with a wide variety of functions. In this case, the DISM Restorehealth command will ensure that our next fix is working properly.
Follow the steps below.
Art Command Prompt (Admin) In the Start menu search bar, right-click and select Execute 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 complete. The process can take up to 20 minutes, depending on the system status. The process seems to get stuck at certain times, but wait for it to complete.
When the process is complete, enter sfc / scannow and press Enter.
CHKDSK is another Windows system tool that will check your file structure. Unlike SFC, CHKDSK will check your entire drive for errors, while SFC will specifically check your Windows system files. As with SFC, run the CHKDSK scan from Command Prompt to repair your computer.
Art command prompt In the search bar on your Start menu, right-click and select the best match Execute as administrator. (Alternatively, press Windows key + X., then choose Command Prompt (Admin) from the menu.)
Next, enter chkdsk / r and press Enter. The command will scan your system for errors and fix any problems along the way.
4. Update your SSD drivers
By and large, Windows 10 takes care of your driver updates. Updates are also automated in Windows 10, so you should never lag behind the update cycle too far. That said, things are sliding around the web and drivers can be damaged for one reason or another.
To check your latest automatic driver updates, go to Update & Security> Windows Update> View update history. Current driver updates are displayed here.
Now enter Device manager In the Start menu's search bar, select the best match. Unfold the Drives Then right click on the driver for your SSD and select Update driver. Choose Automatically check for updated driver software So that Windows automates the update process for you.
Update Windows 10
Another fix is to check if there is an update pending Windows 10. Go to Update & Security> Windows Update. If updates are available, download and install them.
5. Uninstall the software
Did the DPC Watchdog Violation error start after installing new software? In this case, you should remove the software, reboot the system, and see if the image persists.
entrance Programs Select the best match from the search bar on your Start menu. Turn the sort by Drop down menu too Installation dateSort the program list according to the installation date. Uninstall recently installed programs and restart your system. If the DPC Watchdog Violation error goes away, you have found the culprit.

As with many Windows 10 blue screen errors, the DPC Watchdog Violation error is a nuisance. However, if you follow the steps in this list, you can fix DPC Watchdog Violation error without causing too much stress.
