1. Update or Roll Back Drivers
- Press Win + X → Device Manager
- Locate recently updated or suspicious drivers
- Right-click → Update driver or Roll back driver if issues began after an update
- Use only official drivers from your hardware or OEM vendor
- Updating eliminates duplicate object registrations; rolling back fixes instability caused by bad updates.
2. Perform a Clean Boot to Isolate Conflicts
- Press Win + R, type msconfig, and press Enter
- Go to Services tab → Check Hide all Microsoft services → Click Disable all
- In the Startup tab → Open Task Manager → Disable all startup programs
- Reboot and check if the BSOD occurs
- A clean boot helps identify if a third-party driver or application is causing the collision.
3. Run System File Checker and DISM
- Open Command Prompt (Admin)
- Run:
- sfc /scannow
- Then run:
- DISM /Online /Cleanup-Image /RestoreHealth
These tools repair corrupted system files and kernel components to ensure proper object handling.
4. Scan for Malware or Rootkits
- Open Windows Security → Virus & threat protection
- Run a Full Scan and then an Offline Scan
- Use a trusted anti-rootkit tool for deep-level checks
- Malware can inject duplicate object references into the kernel, triggering this error.
5. Check for Registry Corruption
- Open Command Prompt (Admin)
- Run:
- sfc /scannow
- Optionally, use Registry cleanup tools or restore a backup registry hive if corruption is suspected
- A clean registry ensures no duplicate or invalid references for kernel objects.
6. Uninstall Recently Installed Software
- Go to Settings → Apps → Installed Apps
- Identify and uninstall any utilities, drivers, or low-level tools installed just before the BSOD began
- Removing problematic software clears duplicate or corrupted kernel object entries.
7. Perform System Restore
- Open Control Panel → Recovery → Open System Restore
- Choose a restore point from before the BSOD started
- Follow prompts to restore system state
System Restore is effective when the issue is linked to recent driver or system updates.
Final Thoughts
The 0x00000056 OBJECT_NAME_COLLISION BSOD signals duplicate or conflicting object references in Windows kernel mode.
To fix it:
- Update or roll back drivers, run SFC/DISM, and check for malware or registry corruption.
If the issue persists:
- Perform a clean boot, uninstall conflicting software, or revert to a restore point to restore system stability.
Addressing these root causes ensures proper kernel object handling and prevents future BSODs tied to naming collisions or driver conflicts.
