Fix ‘DPC_WATCHDOG_VIOLATION’ Issue In Windows – Guide
The DPC Watchdog Violation error stems from problems with the system hardware and warns that Windows was unable to communicate properly with the hardware. When Windows 10 was first introduced in 2015, there were a number of DPC Watchdog Violation errors related to solid state drives (SSDs), such as outdated SSD firmware, old SSD driver versions, or hardware incompatibility issues. The problem was that SSD manufacturers had not developed and released updated drivers for the new operating system, which caused a variety of issues, including the DPC Watchdog Violation error.
DPC stands for Deferred Procedure Call, which is a system-level process (ie, it runs in the background). A DPC essentially indicates when some piece of hardware wants to communicate with the CPU, but is doing it a little out of order. If the DPC is not resolved within a period of time, it will cause the DPC watchdog violation error (where the watchdog is a process that ensures that the DPC resolves within the allotted time).
Deferred procedure calls work alongside “system interrupts”, which is another system-level process. Whenever software or hardware wants to do something, it “interrupts” the CPU to say what is happening. If the system stays at the interrupt request level (IRQL) for too long, it can also cause blue screen errors.
