DPC watchdog violation has become an annoying problem for windows users recently.

Here, we are going to explain the causes of the problem and put forward some efficient solutions.

What is DPC watchdog violation error?

DPC Watchdog Violation is a common issue for Windows systems. It happens when there are such cases like unsupported SSD firmware, old SSD driver version, hardware incompatibility issues, or system files are corrupted.

How to fix DPC watchdog violation error?

First, we should check if it is related to system update:

Since Microsoft can not fix it temporarily, users should take measures by themselves. Try to remember whether you have updated the drivers on your PC. There is an error of DPC WATCHDOG VIOLATION BSOD when users upgrade their system to windows 10. 

According to an analysis, it can almost be caused by the incompatibility of drivers resulted from iastor.sys. Such situation may attribute to the incomplete compatibility of iastor.sys and windows 10. Microsoft is exploring an effective solution in order to avoid the incompatibility of drivers when we upgrade to windows 10. But if you have already done, you can try the following steps to change problematic drivers with Microsoft storahci.sys, thus continuing to use your computer.

Change SATA AHCI controller

This method is used when the cause of the error is a connected storage device or memory of your computer.

To deal with this situation, you have to change the SATA AHCI controller. This is a driver responsible for data exchange occurring between storage devices in your system and its memory.

The driver acts by verifying the compatibility of the data and providing an efficient output. You can easily solve the DPC Watchdog violation error if you can change the SATA AHCI driver. Here are the steps to perform this change:
