How to Fix INTERRUPT EXCEPTION NOT HANDLED (0X0000003F)
Below are proven methods to resolve this issue, starting with the simplest and progressing to more advanced solutions.
### Method 1: Check for Recent Changes
If the error started after installing new software or updating drivers, roll back recent changes:
- Open Settings > Update & Security.
- Go to Recovery and click Go back to the previous version of Windows. (This option is available if you recently upgraded Windows.)
- If no recovery point exists, uninstall recently installed programs via Settings > Apps > Apps & features.
### Method 2: Run System File Checker and DISM
Corrupted system files can trigger this error. Use built-in tools to repair them:
- Open Command Prompt as Administrator (search for “cmd,” right-click, and choose Run as administrator).
- Run the following commands one by one, pressing Enter after each:
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
- Restart your PC after completion.
### Method 3: Update or Reinstall Drivers
Outdated or conflicting drivers are a common cause. Update them manually:
- Press Win + X and select Device Manager.
- Expand categories like Display adapters, Network adapters, or Universal Serial Bus controllers.
- Right-click any device with a yellow exclamation mark (if present) and select Update driver. Choose Search automatically for drivers.
- If no updates are found, download the latest drivers from the manufacturers website (e.g., NVIDIA, Intel, or your motherboard vendor).
### Method 4: Run CHKDSK to Check for Disk Errors
Bad sectors on your hard drive can cause this error. Scan your disk using:
- Open Command Prompt (Admin) and run:
chkdsk C: /f /r
- If prompted, press Y to confirm. The scan will run on the next restart.
- Wait for the process to complete, then restart your PC.
### Method 5: Test Your RAM and Hardware
Faulty RAM or overheating can trigger this error. Test your memory using Windows Memory Diagnostic:
- Search for Windows Memory Diagnostics, open it, and select Restart now and check for problems.
- Follow the on-screen instructions to complete the test.
- If errors are found, consider reseating your RAM or testing with a different stick if you have multiple modules.
### Method 6: Disable Fast Startup (if applicable)
Fast Startup can sometimes cause conflicts. To disable it:
- Go to Control Panel > Power Options > Choose what the power buttons do.
- Click Change settings that are currently unavailable (requires admin rights).
- Uncheck Turn on fast startup (recommended), then click Save changes.
- Restart your PC.
### Method 7: Perform a Clean Boot
A clean boot starts Windows with minimal drivers/services to identify conflicts:
- Press Win + R, type
msconfig, and press Enter. - Go to the Services tab, check Hide all Microsoft services, then click Disable all.
- Switch to the Startup tab and open Task Manager. Disable all startup items.
- Restart your PC. If the error doesnt occur, re-enable services/items one by one to isolate the culprit.
### Method 8: Use System Restore (if available)
If you have a recent restore point, revert your system:
- Search for Create a restore point, go to System Protection, and click System Restore.
- Follow the prompts to select a restore point before the error occurred.
### Method 9: Check for Overheating or Hardware Issues
Overheating can cause random crashes. Monitor your CPU/GPU temperatures using tools like HWMonitor. If overheating is detected, clean dust from fans, reapply thermal paste, or check cooling systems.
### Method 10: Last Resort Reset or Reinstall Windows
If all else fails, reset your PC (keeping files) via Settings > Update & Security > Recovery > Reset this PC. For a clean install, back up your data first.

FAQ About INTERRUPT EXCEPTION NOT HANDLED (0X0000003F)
Q: Will this error delete my files?
A: No, the BSOD itself doesnt harm your files, but frequent crashes can cause data loss if unsaved work isnt automatically saved. Always save your work regularly.
Q: Can third-party software fix this?
A: While some tools claim to “fix” BSODs, rely on Microsofts built-in utilities (like SFC and DISM) first. Avoid untrusted repair programs that promise quick fixes.
Q: Why does this happen randomly after months of stability?
A: This often indicates a hardware issue (e.g., failing RAM or overheating) or a delayed driver conflict. Test your system with stress tests if the problem persists.
Q: Should I replace my hard drive immediately?
A: Only if CHKDSK or SMART data shows disk errors. Otherwise, the issue is likely software-related.
Q: How can I prevent this in the future?
A: Keep drivers updated, avoid abrupt shutdowns, and use reliable hardware. Regularly run sfc /scannow and monitor system health with tools like Windows Memory Diagnostic.
