About dpc_watchdog_violation error

The appearance of the DPC watchdog violation Windows 10, 11 problem is most often associated with a hardware component, driver, or software. In this case, the first thing to do is check all the data and power cables connected to the computer. This can fix the Blue Screen of Death error. If that doesn't work, download and update the driver called iastor.sys. You can diagnose a system error using the troubleshooting utilities integrated into Windows 10, 11.

The DPC watchdog violation error can occur both independently and with other problems and lead to BSOD. However, there is only one reason in any case. Microsoft offers information to users who have encountered this error. The website states that the DPC watchdog was executed, either because it found one long deferred procedure call (DPC) or because the OS took a long time at the DISPATCH_LEVEL interrupt request level (IRQL). The setting of parameter 1 indicates whether one DPC has exceeded the timeout or the system has collectively spent an extended period of time at the DISPATCH_LEVEL IRQL.

For decryption, the system disk is a hardware component that ceases to be readable. A similar situation is observed when disconnecting the data cable from the internal data storage. Most often, this is due to the problem of incompatibility of devices, lack of BIOS update, error with the SSD, attack of viruses and virus software, or incorrect overclocking.
