While frustrating, this issue is usually fixable with the right steps. Below, well explain what causes this error and provide step-by-step solutions to resolve it.
What Causes the SYSTEM THREAD EXCEPTION NOT HANDLED (0x0000002c) Error?
The 0x0000002c BSOD can be triggered by various factors, including:
- Corrupt system files: Damaged or missing Windows system files can cause instability.
- Faulty hardware drivers, especially graphics or chipset drivers that are outdated or incompatible.
- Malware or virus infections affecting critical system processes.
- Incompatible software, such as poorly coded applications or games.
- Hardware issues, including faulty RAM, overheating, or failing storage drives.
The error often appears during startup, when opening specific programs, or while gaming, but it can also occur randomly. If you see this BSOD, your PC will restart automatically unless disabled in settings.
How to Fix SYSTEM THREAD EXCEPTION NOT HANDLED (0x0000002c)
Follow these methods in order, starting with the simplest and progressing to more advanced solutions. If an earlier step resolves the issue, you can skip the remaining steps.
Method 1: Restart Your PC
The most basic fix is often overlooked but effective. A simple restart can clear temporary glitches causing the BSOD:
- Hold down the power button for 510 seconds to force a shutdown.
- Wait 30 seconds, then press the power button to turn your PC back on.
- If the issue persists after multiple restarts, proceed to the next method.
Method 2: Update or Roll Back Drivers
Outdated or conflicting drivers are a common cause of this error. Focus on graphics and chipset drivers:
- Press
Win + X, then select Device Manager. - Expand categories like Display adapters, System devices, or Sound, video and game controllers.
- Right-click a device (e.g., your GPU), select Update driver, then choose Search automatically for drivers.
- If the issue started after a recent update, right-click the driver and select Properties. Go to the Driver tab and click Roll Back Driver (if available).
- Restart your PC afterward.
Method 3: Run System File Checker (SFC) and DISM
Corrupt 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).
- Copy and paste the following commands one by one, pressing
Enterafter each:DISM /Online /Cleanup-Image /RestoreHealthsfc /scannow - Wait for both commands to complete (this may take 1030 minutes). Restart your PC afterward.
Method 4: Check for Malware
Malware can corrupt system files or drivers. Run a full scan with Windows Defender:
- Open Windows Security (search from the Start menu).
- Go to Virus & threat protection, then click Quick scan. Wait for it to finish.
- If threats are found, follow the prompts to quarantine or remove them. Restart your PC afterward.
Method 5: Test Hardware (RAM and Storage)
Faulty RAM or a failing hard drive can cause this error. Run diagnostics:
- For RAM:
- Open Task Manager, go to the Performance tab, and check for errors under Memory.
- Use Windows Memory Diagnostic (search for it in the Start menu), select Restart now and check for problems, then follow on-screen instructions.
- For storage:
chkdsk /f /r(Run this in Command Prompt as Administrator. It will scan your primary drive and attempt repairs.)
Method 6: Uninstall Problematic Software
If the BSOD appears after installing new software (e.g., games or drivers), uninstall it:
- Go to Settings > Apps > Apps & features.
- Find the suspicious program, click it, then select Uninstall.
- Restart your PC and monitor for improvements.
Method 7: Check for BIOS/UEFI Updates or Overclocking Settings
If youve overclocked your CPU/GPU or have a recent BIOS update, revert changes:
- Enter BIOS/UEFI (usually by pressing
Del,F2, orF12during boot). - Reset all settings to default or disable overclocking.
- Check your motherboard manufacturers website for BIOS updates and flash the latest stable version if needed.
Method 8: Perform a Clean Boot (Advanced)
A clean boot starts Windows with minimal drivers/services to isolate the cause:
- Press
Win + R, typemsconfig, and pressEnter. - Go to the Services tab, check Hide all Microsoft services, then click Disable all.
- Go to the Startup tab, click Open Task Manager, and disable all startup items.
- Restart your PC. If no BSOD occurs, a third-party program or service is likely the cause.
Method 9: Reset Windows (Last Resort)
If all else fails, reset Windows to factory settings:
- Go to Settings > Update & Security > Recovery.
- Under Reset this PC, choose Keep my files or Remove everything (back up important data first).
- Follow the prompts to complete the reset.
