11 Ways to Fix DPC Watchdog Violation BSOD in Windows 10
Our solutions and tools make BSOD troubleshooting easier than ever
- The DPC_WATCHDOG_VIOLATION BSoD error is caused by a hardware component, its driver, or a software program.
- To resolve this blue screen issue, check your data and power cables.
- You may also try to update and replace the iastor.sys driver or run a full system scan.
One thing persistent in all Windows versions is the dreaded BSOD (Blue Screen Of Death) and the DPC_WATCHDOG_VIOLATION error remains one of the most annoying.
This is a BSOD bug check that has the code 0x00000133. DPC is an acronym for Deferred Procedure Call, and the Watchdog term refers to the bug checker which monitors or tracks your programs and the performance of your PC.
We will try to shed some light on this matter and help you fix the issue on Windows 10 PCs.
What is causing the DPC watchdog violation?
In some cases, this problem comes along with other BSoDs, and they all have a common cause. For example, if you check the official Microsoft website, you will find some information on this error:
This bug check indicates that the DPC watchdog executed, either because it detected a single long-running deferred procedure called (DPC); or because the system spent a prolonged time at an interrupt request level (IRQL) of DISPATCH_LEVEL or above.
The value of Parameter 1 indicates whether a single DPC exceeded a timeout; or whether the system cumulatively spent an extended period of time at IRQL DISPATCH_LEVEL or above.
Microsoft stated that Windows 10 has stopped working because it could not get a response from a hardware component, its driver, or a software program related to it.
Most often, the hardware component in question is a disk drive; Windows crashes once the disk becomes unreadable (similar to unplugging the data cable of the HDD when it’s in use).
In some cases, the problem can be a hardware incompatibility, BIOS or UEFI that has not been updated, SSD issues, overclock not done correctly, or even a virus infection.
