Fix: Lenovo Legion 5 Keeps Freezing (Dpc_Watchdog_Violation)

Read here how to fix this issue where the Lenovo Legion 5 keeps freezing and getting the BSOD error "DPC_WATCHDOG_VIOLATION."

Many users have complained that their Lenovo Legion 5 keeps freezing randomly and getting BSOD with the error “DPC_WATCHDOG_VIOLATION.” In this article, I will tell you how to fix this issue.

This issue stems from compatibility issues between the drivers provided by Nvidia GeForce and the Lenovo Legion factory settings, which causes conflict with other drivers making your laptop freeze.

To fix this issue, go to the Device Manager, expand USB-Controller and disable NVIDIA USB 3.10 eXtensible Host Controller -1.10(Microsoft). The Nvidia driver installs this device, and it doesn’t exist in your laptop; thus, it causes conflicts with other drivers making your laptop freeze.

Here are the step-by-step instructions:

  1. Enter Device Manager on Windows Search and click on Open:
  2. In the Device Manager, expand USB-Controller (or “Universal Serial Bus controllers”).
  3. Right-click on NVIDIA USB 3.10 eXtensible Host Controller -1.10(Microsoft) and click on Disable device:
  4. Restart your PC.

This should fix the issue for you.

If your Lenovo Legion keeps restarting and the problem reappears, try to uninstall the current drivers and install Lenovo factory drivers, as explained next.

Your Lenovo Legion 5 keeps freezing and displaying the error “DPC_WATCHDOG_VIOLATION” due to an incompatibility caused by Nvidia drivers. So, fixing this issue involves uninstalling/disabling the faulty drivers or installing the right one.

To fix this issue, go to Device Manager, expand Universal Serial Bus controllers and disable the NVIDIA USB 3.10 eXtensible Host Controller -1.10(Microsoft).

If this doesn’t work, try to uninstall Nvidia graphic drivers and components, reboot your PC, and then install the NVIDIA VGA Driver from Lenovo Support, and reboot your PC again. When installing, ensure only to install the NVIDIA PhysX and the NVIDIA Graphics Drivers.

Another common bug in Lenovo laptops is the firmware update restart loop on Lenovo 14W laptops. I’ve written an article about that.
