Recommended: To easily install drivers automatically, use the tool below.
Here is a detailed guide on understanding the DPC watchdog violation error, why it occurred, and how to resolve the issue successfully.
What is a DPC Watchdog Violation error?
A DPC Watchdog Violation is an error occurring in your Windows system. DPC is the abbreviated form for Deferred Procedure Call. Watchdog denotes Bug Checker, which helps monitor all Windows processes and the background performances. Its check value is about 0x00000133.
The violation message appears when it waits longer than usual such as over 100 microseconds. It will show the error message if it does not find a response.
Why Do I Keep Getting Dpc Watchdog Violation? What Causes It?
Several factors can cause the dpc watchdog violation error message. Here are the factors that lead to a DPC Watchdog error in Windows 10:
- The blank blue screen error, also known as BSOD error (Blue Screen of Death), is due to hardware incompatibility in your PC or laptop. You will find the popup screen when you connect incompatible hardware such as an AMD Graphic card, NVIDIA, or even an external drive.
- If the firmware or driver of the hardware you are connecting to your device is not supported by your device, you will find the BSOD popping up. This can happen when you connect the external hardware for the first time or even when you connect hardware after a couple of months.
- The conflict between two software applications can also cause a violation error. If the software you are installing in your device is incompatible with software present in your device already, it can cause the DPC watchdog violation blue screen error. You can find the details for this in the device manager.
- Corrupt system files may also contribute to this issue. Your system files may get corrupted for several reasons, but malware infection is the most common.
As you can see, the factors behind the bug trigger are plenty. You can face the issue while updating your Computer or installing software, which can also occur randomly.
DPC Watchdog errors can be caused when the system needs to refresh all its hardware drivers. It may also occur when your drive has files that your present Windows 10 version does not support.
How to Fix DPC Watchdog Violation Error
There are several ways to fix the DPC Watchdog Violation BSOD error.
Fix 1: Change Standard SATA AHCI controller
This method is used when the cause of the error is a connected storage device or your computer’s memory.
To deal with this situation, you must change the Standard SATA AHCI controller. This is a driver responsible for data exchange between your system’s storage devices and its memory.
The driver acts by verifying the compatibility of the data and providing an efficient output. You can quickly fix the DPC Watchdog violation error by changing the SATA AHCI driver. Here are the steps to perform this change:
Press the X button and Windows key button simultaneously.
Choose the ‘Device Manager’ option in the menu page that opens.
When you go to the Device Manager option, expand the IDE ATA ATAPI controller feature here.
Expand the controller feature and select Standard SATA AHCI controller under IDE ATA/ATAPI controllers. Use right-click the Standard SATA AHCI Controller and click properties.
To ensure you have chosen the suitable controller from the driver, choose Driver software details from Driver Tab. Check whether iaStorA.sys is under the driver list. Now click on the OK button to exit.
In the Driver tab, choose the ‘Driver’ option and click on the ‘Update driver’ feature on the IDE ATA ATAPI controller.
Next, select Browse my Computer for the driver software option.
Now choose, ‘Let me pick from a list of device drivers on my computer.’
After choosing “Let me pick from a list of available drivers on my computer,” choose ‘SATA AHCI Standard Controller’ and select the ‘Next’ button to update the driver software. Complete the procedure onscreen.
Restart your system. To avoid the error from recurring again, it is best to repeat this procedure every time there is a Windows update.
Fix 2: Update your drivers
If an old firmware version is present in your Solid State Drive (SSD), which your Windows 10 does not support, you have to update the SSD firmware version to avoid the DPC watchdog error. Here are the steps:
Press the Windows button and E simultaneously to open File Explorer or choose Computer/My/This PC from the desktop.
Find the Computer from the panel’s left side and use right-click to open it. Choose the Manage option.
In the popup window that appears, choose the ‘Device Manager’ option present on the left side.

Fix 5: Check Software and Hardware Compatibility
While you may expect an external device to work smoothly right from the time you start using it, this is not. You may face a violation error, and the drive may not be compatible with the hardware or software present in your device. Here is a simple way to resolve this issue.
Hardware Compatibility – If you are using multiple devices, you must plug in the device one by one and check their compatibility to identify the driver causing the error.
When you identify the particular device, you can check its specs, find out about compatibility with your system, and exchange it for another compatible device.
Software Compatibility – For software conflicts causing the violation error, you use the trial and error method as in the hardware compatibility testing. Once you identify the software, uninstall and restart your system to determine if the error persists. If this does not work out, follow the steps below:
Press Windows Key and R buttons simultaneously after opening the Windows Run feature.
Go to ‘Control Panel’ by entering it in the dialog box, and press ‘Enter.’
Choose Uninstall a Program option from the control panel
In the applications list, under the ‘Uninstall a Program’ feature, find the software you had installed earlier by checking the installation date and time present on the top portion of the table.
You can uninstall the programs you suspect are causing the issue from the time and date they were installed.
Once you uninstalled the program, restart the system to determine if the issue has been rectified.
The above five steps will take care of the DPC Watchdog Violation that has been frustrating you. If the above steps are ineffective, you can also use a professional repair tool for PC error correction. But the above steps are simple and can be done to rectify the error effectively.

DPC is short for Deferred Procedure Call. The “Watchdog” part of the error refers to the part of the program that watches for bugs. The problem originates from a solid state drive that was incompatible with Windows. It can crop up from time to time, most often due to hardware issues.
The violation takes place when Windows doesn’t receive a response from hardware or some computer component fast enough. Updating a driver and checking connections can help straighten out these problems.
Remove All External Devices
The DPC Watchdog Violation can be caused by an incompatible drive or device. Remove any external devices (minus the mouse and keyboard). If you have hooked up a new external hard drive, a printer, or another accessory, disconnect it from your computer and then restart.
If the problem doesn’t happen again, then you can deduce the problem lies with one of the devices. Connect them one at a time until you can pinpoint which device is causing the error.
Check Cable Connections
One step in correcting a DPC Watchdog Violation is to make sure your power cables and data cables are securely connected within your PC. This isn’t difficult to do, even for total beginners. Open the side of your PC case and look for cables that are hanging loose.
Apply slight pressure at connection points to ensure a solid connection has been made. If cables are loose and you aren’t sure where they should connect, check your PC’s manual.

Windows recommends replacing this particular driver, as it is a known culprit of the DPC Watchdog Violation error.
Perform a Disk Check
If the cable and driver updates did not correct the problem, your next step should be to perform a disk check on your entire system. Do this by opening the Command Prompt. Press Windows R to open the Run menu, and then type cmd to open the Command Prompt. Once open, enter the following:
If your hard drive partition is something other than C:, just replace the C: with the correct drive name.
This will perform a check on your system that looks for and repairs any issues within the logic of your drive. In many cases, this simple command can solve the DPC Watchdog Violation.
