Remove All Connected External Devices
Before going further or applying any other methods, please remove or disconnect all external devices that plugging onto your Windows PC, except keyboard and mouse to see whether the issue persists or not.
Those devices could be an external hard drive, external solid-state drive, printer, or scanner. Once those devices removed and the problem is gone, then definitely one of those devices causes the error. To determine which one caused the BSOD error, connect one device at a time to check.
Update Firmware Of Your Solid State Drive
In case you use solid-state drive (SSD) on your computer, I would recommend you download the latest firmware version of it from the manufacturer’s website and update your SSD.
Sometimes, your Windows can’t handle your SSD correctly until the firmware is updated.
To find out the model number of your SSD, following these instructions:
- Press Windows + E to launch File Explorer
- Look at the left sidebar, right-click on My Computer and choose Manage. It could have a different name, such as This PC, depending on the version of Windows you are using.
- In the Computer Management window, look at the left sidebar and choose Device Manager.
- From the list of Disk drives, you can find out the type of SSD you are using, plus the model number.
After determining the model number of SSD, go to the manufacturer’s website, search for the new version of firmware if available, then download and update for your SSD.
Check Corrupted System Files On Your Windows
Corrupted system files are one of many reasons that lead to this Blue Screen error. In order to fix the DPC_Watchdog_Violation error on your Windows computer, you should check and verify Windows system files to make sure they are not corrupted. If there were any problems with those files, the process will fix them automatically.
To get started, open the Command Prompt program with administrative privileges. Next, in the Command Prompt program window, type:
- CHKDSK C: /F /R
and then press Enter.
Because the currently drive C:\ is using by the Windows system, that’s why the “Check Disk” process can’t start. It will ask you to schedule the checking in the next time when your computer reboots. If you agree, type Y and then press Enter.
After that, restart your computer.
Your Windows computer will be rebooted, and start to verify the system files. It might take a while to complete. Please do not turn off the computer while it’s checking and verifying.
Scan And Fix System Files
Sometimes, scanning and fixing Windows system files will help to fix the DPC Watchdog Violation error on your computer. In order to scan and fix system files, open the Command Prompt program as an administrator.
Next, please type the following command in Command Prompt:
- SFC /scannow
and then press Enter.
It will automatically scan and fix errors in your Windows system. Wait for the process is completed and then restart your computer.

The information is also available in the Event Viewer, including the STOP code and other parameters.

The software is very easy to use. All you need to do is that download, install and then use. It will automatically search for the minidump file and display the result to you.

Unable To Boot Up Your PC When Getting DPC Watchdog Violation BSOD Error?
Instead of successfully accessing your Windows PC after getting this Blue Screen of Death error, your computer sometimes puts itself in a loop:
- Boot up -> Display BSOD error -> Restart -> Repeat
So, if you want to get rid of the DPC Watchdog Violation error, you have to do it in Windows Safe Mode.
How To Access Safe Mode In Windows 7
To access Safe Mode in Windows 7, press F8 immediately after your PC is restarted or powered on. I often press F8 when I hear the “beep” sound, and I press it several times.
In the Advanced Boot Options menu, use the up & down arrow keys to select the mode you want to access: Safe Mode, or Safe Mode with Networking. Then press Enter.
How To Access Safe Mode In Windows 10
To access Safe Mode in Windows 10, you need to prepare a Windows installation media and then boot up from it. It could be a DVD installation or a USB bootable device.
Note: This method is only used when you are getting a BSOD error, and it prevents you from accessing your PC. If you can access your computer normally, then there are some other easier ways to access Safe Mode.
After booting up from it, choose “Repair my computer” -> “Troubleshoot” -> “Advanced options” -> “Startup Settings“.
Next, choose “Restart” and then press F5 to access Safe Mode with Networking mode. You can choose other options that fit your needs.
Update #1: According to a few unconfirmed reports from users, after turning off/disabling AVG antivirus software, this BSOD error is no longer occurs.
I haven’t tested this solution yet because I wasn’t in the exact situation. I also don’t know the relation between this error and AVG antivirus yet. So this is just a reference tip.
Many users reported after reinstalling the display driver that the DPC Watchdog Violation error is fixed. So, you want to try, boot up your PC to Safe Mode.
After that, open Device Manager, and then locate and expand the Display adapters option. Choose your display adapter and then right-click on it and select Uninstall.
In the next step, check the “Delete the driver software for this device” checkbox and then click the “OK” button.
Then reboot your Windows PC, but in normal mode and install the display driver. If you are using Windows 10, it will do it automatically with an Internet connection.
Update Chipset Driver To Fix DPC Watchdog Violation Error In Windows 10
