- Go to Control Panel and open Device Manager.
- Once open, examine the list of installed devices and see if any device driver has a yellow exclamation mark besides it.
- If you locate one, right click on the driver.
- Let Windows update the driver.
However, if the update fails, then right-click on the driver and click on Disable.
- Restart your PC.
See if that solves the problem. If not, continue reading.
Method 3: Disable your antivirus
An antivirus program can also be the reason behind the DPC Watchdog Violation error. So to deal with that, go to the settings of your antivirus program. Open settings and turn off all of the Protection options there. Or disable the antivirus program, which is better. Just right-click on the antivirus program icon on the taskbar and disable it. After doing that, restart your PC and check if the error still shows. If it doesn’t, then look for another antivirus program.
Method 4: Disable fast startup
To disable the Fast Startup, follow the below-mentioned steps:
- Open Control Panel.
- Once open, look for Power Options.
- Click on Choose what the power buttons do.
- From the available options click on change settings that are currently unavailable.

- Then go to Properties > Tools and click on Check Now.
- Check both the boxes there and click on Start.
- A dialogue box will open in which click on Schedule disk check.
- Restart your PC.
Method 7: Update Firmware of your Solid State Drive
Sometimes Windows is unable to handle the SSD if the firmware is not updated. If you have SSD on your computer, download the latest firmware version of it from the manufacturer’s website. Use that to update your SSD.
Before downloading, you have to find the model number of your SSD. To do that, follow these steps:
- Press Windows + E to open File Explorer.
- On the left, you’ll find My Computer/This PC, right click on it.
- From the available options choose Manage.
- A Computer Management window will open. Look at the left and choose Device Manager.
- You will see a list of Disk Drives where you can find out the types of SSD and the model number of the SSD you’re using.
After you find out the model number, download its latest firmware version from the manufacturer’s website.
Method 8: Check Corrupted System Files on Your Windows
This Blue Screen error can also be caused by corrupted system files. If this is the case, check and verify all the Windows system files. If any of the files are corrupted, or there are problems with the files, the following process will fix them:
1- Open the Command Prompt program as an administrator.
2- In the window type CHKDSK C: /F /R and press Enter.
3- After you do that it will ask you to schedule the disk check the next time when the computer reboots. When you see this type Y and press Enter.
4- Restart your computer.
This way your computer will reboot, and the system files will be verified. Though, remember not to turn off your computer while the process is completing – it might take a while.
Method 9: Scan and Fix System Files
The error can also be fixed by scanning and fixing the Windows system files. Follow these steps to scan and fix the system files:
- Open Command Prompt program as an administrator.
- In the window type SFC /scannow and press Enter.
Wait for the process to complete.
- Restart your computer.
That will fix all the errors in your Windows system.
Method 10: Reinstall All Network Drivers
To do that, follow these steps:
- Start your PC in Safe Mode.
- Open the Device Manager.
- Look for drivers under the Network adapters.
- Right click on the drivers and disable them.
- Restart your PC in normal mode.
If that solves the error, you’ll know that the drivers are the source. Once made sure, uninstall the network drivers and reinstall the latest versions.
However, remember that once you uninstall the network drivers, your PC won’t connect to the internet. You’ll have to download the drivers on another PC and then transfer the files to your PC.
Method 11: Use BlueScreenView to find out the Cause
When the DPC Watchdog Violation error occurs, a minidump file gets created and stored on your computer: C:\Windows\Minidump. You can download BlueScreenView from Nirsoft to view the information available in the Event Viewer. This will help you determine the cause behind this BSOD error.
Once you download the software, it will automatically search and display the result for you. Then you can easily know the reason and find the right solution for that.
Method 12: Reinstall Windows
If nothing else works, you should reinstall a fresh version of Windows from a Windows DVD. This is not really a solution but can work.
Hopefully, one of these methods worked for you and helped you fix the DPC Watchdog Violation error.
