How can I fix DPC WATCHDOG VIOLATION errors?



1. Check your cables

As you can see, there are a number of causes for the DPC WATCHDOG VIOLATION error, but luckily most of them can be ruled out with no effort. 

For instance, the first thing you should do is check all the disk data/power cables. In some cases, if they are not properly plugged in, the system might read that the disk is unavailable and crash.

If all the cables are intact and properly plugged in, you might want to move on and check the health of the disks.


2. Use a dedicated tool

Fortunately, there are great software programs that can help you to diagnose, troubleshoot and solve numerous blue screen error and a lot more other issues.
