Fix DPC Watchdog Violation error in Windows 10


For instance, the first thing you should do is check all the disk data/power cables from your computer. In some cases, if they are not properly plugged in, the system might read that the disk is unavailable and crash.

If all the cables are intact and properly plugged in, you might want to move on and check the health of the disks.


2. Replace the iastor.sys driver

  1. Right-click the Start icon and select Device Manager.
  2. Expand the IDE ATA/ATAPI controllers.
  3. Select the controller with SATA AHCI in its name (such as Standard SATA AHCI Controller).
    • To verify that you’ve selected the right controller, right-click the controller, go to Properties, click the Driver tab, and then Driver Details. Verify that iastor.sys is a listed driver, and click OK.
  4. From the Driver tab select Update Driver.
  5. Select Browse my computer for driver software.
  6. Select Let me pick from a list of device drivers on my computer.
  7. Select Standard SATA AHCI Controller.
  8. Click Next, then Close, and then restart the PC.

Microsoft suggests that you should replace the driver that triggers this error message, meaning the iastor.sys driver with the storahci.sys driver.


3. Check your disk

  1. Type cmd in the Search tab in Windows 10.
  2. Click on Run as administrator to start Command Prompt with elevated privileges.
  3. Type the following command and press Enter to execute it (Replace C with the letter of your hard drive partition): chkdsk C: /f
chkdsk

Note: If you do not use the /f parameter, chkdsk displays a message that the file needs to be fixed, but it does not fix any errors. The chkdsk D: /f command detects and repairs logical issues affecting your drive. To repair physical issues, run the /r parameter as well.

If you’re still running Windows 7, go to hard drives, right-click the drive that you want to check and select Properties, then Tool. Under the Error checking section, click Check.

Also, keep in mind that Microsoft is no longer supports Windows 7 so you should upgrade to Windows 10 as soon as possible.

There are a number of utilities you can use to check all the health-related aspects of your drives. For more information on the best tools that you can install to check your hard drive’s health, check out this list.

If you own an SSD, you might want to look for a firmware update (if you didn’t update it from the start). Keep in mind that if you update your SSD’s firmware, you will most likely lose all data from it.


4. Update your drivers

Updating all the drivers from your computer is another way to go if you have stumbled on in the DPC_WATCHDOG_VIOLATION. Check your components for their manufacturers and models and then check their websites for Windows 10 or previous versions compatible drivers.

Also, if there aren’t any Windows 10 ready drivers, contact them for more information.

Still, in the updating area, you should check the website of your motherboard’s developer for BIOS updates. Sometimes, if a BIOS is getting old and you add new hardware or operating systems to it, it might not work properly.

We strongly recommend DriverFix to automatically download all the outdated drivers on your PC. It’s very reliable can get the job done in just a few seconds and clicks.

6. Run a full system scan

Scanning your computer for viruses is something that you should do all the time, even if you don’t have the DPC_WATCHDOG_VIOLATION error.

However, if you suffer from this issue, then you might want to scan your computer thoroughly and seek out any malware that might be hiding in it.

There are lots of great antivirus programs out there that can do a great job in searching for all kinds of malware and other errors. Check out this article to see what antivirus tool we recommend you to install on your computer.

Meanwhile, you can also use Windows Defender to scan your device.

Here’s how to run a full system scan on Windows 10:

  1. Go to Start, type Windows Security, and click on the app from the results.
  2. In the left-hand pane, select the Virus & threat protection option.
  3. In the new window, click on the Scan options.
  4. Check the Full scan option and click on the Scan now button below to launch a full system malware scan.

7. Check software and hardware incompatibility issues

  1. Click the Start button and select the Settings option (the cogwheel).
  2. Select Update & Security and then Troubleshoot.
  3. Under Additional troubleshooters, select the Program Compatibility Troubleshooter and run it.

Most programs created for earlier versions of Windows will work on newer OS versions. However, some older programs might run poorly or even cause severe errors, such as the DPC WATCHDOG VIOLATION error.

You can run the Program Compatibility Troubleshooter as indicated above to automatically detect and fix some of the most common issues.

Hardware incompatibility is something to take into account also. If you’ve built a new computer and installed Windows 10, and nothing else, and you get this problem, then some components might not work well with each other or with the OS.

In this scenario, you should do more research on each component and if you don’t find anything of use, you should contact the store and get some tech support.

Keep an eye out for hardware that wasn’t installed properly. Most of the times, users don’t install the RAM correctly and a part of it doesn’t make contact.

If you want to check the RAM, take the DIMMs out and place them carefully back in, ensuring that you hear the click and that they are in place.


8. Remove the recently installed software

  1. Go to Start, type Control Panel, and select it from the results.
  2. Click on Programs and Features.
  3. Select the program(s) recently added and click on the Uninstall/Change button.

Then restart your computer, and see if the issue has been solved.

If you recently installed new software on your computer, try uninstalling the respective tools. Sometimes, third-party software may cause severe issues on your computer, including the DPC WATCHDOG VIOLATION error.


9. Run system restore

9.1 Run system restore in Windows 10

  1. Go to Settings, click on Update & Security, and select Recovery under the left pane.
  2. Click on Get Started under Reset this PC and choose to Keep your files.recovery options reset this pc

  2. Go to System Protection and click on System Restore.
  3. Click Next and choose the preferred restore point in the new window.
  4. Once you’ve selected your preferred restore point, click Next and then Finish.
  5. Your PC will restart and the restoring process will start.

After the procedure has been completed, check if the DPC WATCHDOG VIOLATION error persists.

If the problem has occurred after you’ve installed a driver or modified anything on the software level of your computer, then you should do a System Restore to a point from before you’ve modified anything like instructed in the steps above and see if the problem still persists.

If indeed it was something you did or installed, then this should fix your Windows 10 DPC WATCHDOG VIOLATION problems.
