The blue screen of death bug check 0x00000133 is related to DPC Watchdog violations.
DPC refers to the Deferred Procedure Call. Watchdog refers to your PC performance and your Windows programs, which are monitored by the bug checker.
Your PC watchdog (aka bug checker) is overwhelmed when you see the Violation message. This is usually the result of a DPC running too long or an interrupt request level (IRQL) of DISPATCH_LEVEL or higher.
What would cause the DPC Watchdog Violation error?
Your driver(s) might be outdated or you might have installed them incorrectly, resulting in this error. DPC Watchdog Violation can easily occur when you watch a video online if you haven’t installed the video card driver for your new operating system.
You can also encounter this problem if your operating system is not compatible with your hardware. This error can occur when you have installed a new hardware device on a computer that does not support Windows 10’s external hard drives, or if your computer does not support the external hard drive anymore.
Although not as common as the two causes above, a software conflict may sometimes cause this error.
Fix 1: Drivers should be updated
To update your driver, look for storahci.sys in the properties of your SATA AHCI controller driver and follow the steps.
Moreover, outdated drivers for your hardware devices are one reason for DPC Watchdog Violation. Check to make sure you have the right drivers for all your devices, and update those that don’t.
Manual driver update – The most recent correct driver can be found by going to the manufacturer’s site and searching for it.
Automatic driver update – Driver Easy automates the process of updating your drivers for you if you lack the time, patience, or computer skills to do it manually.
Your system will automatically be recognized by Driver Easy and the right drivers will be downloaded. The user does not need to know how their computer works, does not need to risk downloading the wrong driver or is not likely to make mistakes when installing. With Driver Easy, everything is handled for you.
First, download and install Driver Easy. Then, run Driver Easy and click on Scan Now button. Once Driver Easy has scanned your computer, it will identify any problem drivers.
Update All automatically downloads and installs the correct version of all the missing or out-of-date drivers on your computer. To do this, you’ll be prompted to upgrade to the Pro version of Driver Easy.
Alternatively, if you’re comfortable manually installing drivers, you can click ‘Update’ next to each flagged device in the free version to automatically download the correct driver. Once it’s downloaded, you can manually install it.
Fix 2: Make sure your hardware and software are compatible
There are several factors that may cause this error, including hardware devices that are incompatible with your PC’s operating system and/or software programs that are conflicting.
Hardware compatibility should be checked
Remove all external devices from your PC (leave only the mouse and keyboard connected), then restart it. If you have external devices connected, such as an external hard drive or a USB flash drive, unplug them first.
Make sure this error doesn’t persist. When the error stops occurring, plug all your external devices back in one by one, then restart your PC. In the event that the error occurs again after a certain device, you have already identified the culprit. Your PC will either need to be replaced completely with this device, or its driver will need to be updated.
Make sure your software is compatible
The error may have happened only very recently. Check your PC to see if any changes were made. Do you have a new application installed, or are you planning to upgrade some software?
Perhaps running a system restore can help you get back to your PC’s previous state if you’re not sure what changes you have made.
Fix 3: Run Event Viewer
However, this method will not provide you with a solution but could help you find the DPC Watchdog Violation-related driver or device.
You need to press the Windows logo followed by X while using your keyboard. Select Event Viewer from the drop-down menu.
Click Windows Logs, then click System on the left side of the panel.
You will be able to see some entries in the middle section of the panel. When you view the ones marked by Error or Warning, you will see how many specific issues occurred during a certain timeframe.
