1. Identify the Cause
The first step in addressing the DPC_WATCHDOG_VIOLATION error is identifying the underlying cause. The error commonly points to problems with your device’s drivers, SSD firmware, or hardware connections.
Key options to explore:
- Hardware Drivers: Issues with hardware drivers, particularly for SSDs.
- Outdated Firmware: An SSD with outdated firmware that doesn’t communicate properly with the OS.
- Corrupted System or Disk Files: Corrupted system files or a malfunctioning disk could also be at fault.
Experts Insight: In my experience, this error tends to pop up more often after installing a new SSD without immediately updating the firmware or drivers. If you’ve recently upgraded your hardware, start there.
2. Update SSD Firmware
Outdated SSD firmware is a frequent cause of DPC_WATCHDOG_VIOLATION. It’s essential to ensure that the SSD firmware is up-to-date.
Steps:
- Visit your SSD manufacturer’s website (such as Samsung SSD Downloads) and check for the latest firmware version.
- Download and install any available firmware updates.
- Reboot your computer to complete the process.
Expert Note: Pay attention to your SSD model and firmware compatibility before downloading updates. I’ve seen users accidentally update with incompatible firmware, leading to further issues.
3. Update SATA AHCI Controller Driver
Sometimes, the SATA AHCI controller driver malfunction is the root cause. Here’s how to update it easily via Device Manager.
Steps:
- Open the Device Manager by right-clicking the Start menu and selecting “Device Manager.”
- Expand the “IDE ATA/ATAPI controllers” section.
- Right-click on Standard SATA AHCI Controller, and select “Update Driver.”
- Choose “Search automatically for updated driver software,” and allow Windows to check for a suitable update.
Expert Option: You can also manually download these drivers from your motherboard’s or laptop’s manufacturer’s support page for more reliability. For example, for an Intel-based system, you may need the Intel Rapid Storage Technology (IRST) driver, which you can get here at Intel’s official download site. Alternatively, EaseUS DriverHandy offers an automated way to scan for and update all outdated drivers on your system, saving time and effort.
4. Run System File Checker (SFC)
Corrupted system files can also contribute to this issue. To automatically repair these files, use the System File Checker (SFC) tool.
Steps:
- Open Command Prompt as an Administrator (right-click Start > Command Prompt (Admin)).
- Enter the following command:
sfc /scannow - Hit Enter and let the tool scan and correct any corrupted files it finds.
5. Run Check Disk (CHKDSK)
Another possible cause could be corrupted file sectors on your hard drive. Running chkdsk will scan your disk for errors and fix them.
Steps:
- Open Command Prompt as an Administrator.
- Run the following command:
chkdsk /f /r - When prompted, type Y to schedule the task for the next system restart.
- Restart your computer to let the disk scan and fix errors.
Note: If your drive has bad sectors, this could be a longer process. However, it’s often worth the wait as it can catch and fix the root cause.
6. Remove External Devices
External devices like USB drives, printers, or external hard drives can sometimes interfere with your system’s operation and trigger the DPC_WATCHDOG_VIOLATION error.
Steps:
- Remove all external devices connected to your machine.
- Reboot the computer.
- Check if the issue persists.
If the error goes away, one of the devices may be incompatible or faulty.
7. Roll Back Graphics Driver (Optional)
If the error started occurring after a graphics driver update or new GPU installation, the driver itself could be problematic.
Steps:
- Open Device Manager.
- Expand the “Display Adapters” section.
- Right-click on your GPU and click on Properties.
- Go to the Driver tab and select Roll Back Driver.
8. Check Event Viewer Logs
If you’re still unsure of the cause, investigate further using Event Viewer to analyze crash logs.
Steps:
- Open Event Viewer by typing it into the Windows search bar and hitting Enter.
- Check the logs under “System” for any recent error reports related to DPC_WATCHDOG_VIOLATION.
- Look for an error code and module names that might provide more specific information about the component causing the error.
Tip: This is an advanced move. If the log indicates an error with something like
iaStorAC.sys, then it’s likely related to Intel Rapid Storage drivers.
9. Update Intel Rapid Storage Technology (IRST) Driver
If Event Viewer or crash logs point to the iaStorAC.sys driver, you need to update the Intel IRST driver.
Steps:
- Visit the official Intel Download Center.
- Search for the latest Intel Rapid Storage Technology Driver compatible with your system.
- Download and install the update, then reboot.
10. Perform Startup Repair
If you continue receiving the error, consider running Startup Repair.
Steps:
- Boot your system into Advanced Startup (Hold Shift and press Restart within the Start Menu).
- Navigate to Troubleshoot > Advanced Options > Startup Repair.
- Follow the on-screen instructions to complete the repair.

Frequently Asked Questions (FAQ)
Q1: What exactly causes the DPC_WATCHDOG_VIOLATION error?
This error is primarily caused by outdated or incompatible drivers, corrupted system files, or SSD firmware that is not up-to-date. Sometimes, external devices or hardware conflicts can result in this issue.
Q2: How can I avoid further BSOD issues after fixing DPC_WATCHDOG_VIOLATION?
Stay on top of driver updates, including SSD firmware and SATA/AHCI drivers, and regularly check your system files for corruption using built-in tools like SFC. Avoid installing unverified drivers or software that may interfere with system performance.
Q3: Is it safe to run CHKDSK or SFC?
Yes, both tools are designed to scan and repair system files or disk issues without affecting your files. However, CHKDSK especially can take some time if you have a large hard drive, or if it needs to correct multiple errors.
Q4: Can faulty RAM cause DPC_WATCHDOG_VIOLATION?
While rare, failing RAM could theoretically trigger this error. However, it’s more likely that SSD, drivers, or external devices are the cause.
Q5: Should I reinstall Windows if the error persists after these steps?
Reinstalling Windows should be considered a last resort, but if these steps don’t resolve the issue, there may be deeper, system-level corruption that requires a fresh installation of the OS.
