Check your cables

As you can see, there are a number of reasons for the DPC_WATCHDOG_VIOLATION error, but fortunately, most of them can be easily excluded.

For example, the first thing to do is to check all the data and power cables on your computer. In some cases, if they are not properly connected, the system may read that the hard disk is not available and crash.

If all cables are intact and properly connected, you can continue and check the status of the hard disks.

Upgrading your solid-state drive firmware

Update SSD Drive Firmware

If you are using a solid-state drive (SSD) on your computer, I recommend that you download the latest firmware version from the manufacturer’s website and update your SSD. Sometimes your Windows cannot properly manage your SSD until the firmware is updated.

To find your SSD model number, follow these instructions:

  1. Press Windows + E to start File Explorer.
  2. Look in the left sidebar, right-click My Computer and select Manage. It may have a different name, for example This PC, depending on the version of Windows you are using.
  3. In the Computer Management window, look at the left sidebar and select Device Manager.
  4. In the drive list, you can see the type of SSD used and the model number.
