DPC (Deferred Procedure Call) Watchdog Violation is a blue screen of death (BSOD) error that occurs when Windows detects an unexpected change in the system's performance, which can be caused by various factors such as a failing hard drive, overheating issues, or malware infections. To fix DPC Watchdog Violation on a large hard drive, start by running a diagnostic test on your hard drive to identify any potential issues. You can use tools like CrystalDiskInfo or HDDScan to check for errors and bad sectors.
If you find any issues, consider replacing the faulty hard drive with a new one. Alternatively, you can try to repair the damaged disk using built-in Windows tools or third-party software.
Another step is to ensure that your system's drivers are up-to-date, as outdated drivers may cause system instability and lead to DPC Watchdog Violation errors. Regularly update your drivers, especially those related to disk controllers and storage devices.
You can also try disabling the 'Enhanced Power Management' feature in your BIOS settings, as this can help reduce system resource utilization and prevent DPC Watchdog Violation errors. Additionally, consider running a virus scan and malware removal software to detect and remove any malicious programs that may be causing the issue.
In some cases, simply rebooting your system after each error occurrence may resolve the problem, but it's recommended to address the root cause by addressing the hardware or driver issues mentioned above.
