Disk errors may cause storage operations to freeze and trigger the watchdog violation.
Run the disk repair command:
chkdsk /f /r
This process scans your drive and repairs bad sectors.
Method 6: Update SSD Firmware
Some SSD models cause DPC watchdog errors due to outdated firmware.
Visit your SSD manufacturer website and install the latest firmware update.
Common affected brands include:
- Samsung SSD
- Kingston SSD
- Western Digital SSD
Updating firmware often resolves storage controller conflicts.
