When this error arises, it can cause system instability and crashes, making it imperative to address it promptly. In this detailed guide, we will walk you through the steps to effectively resolve this issue and ensure your system runs smoothly.

Understanding Error Code 0x0000009C

The 0x0000009C error code signifies a machine check exception, which is generally a hardware-related error that the processor detects. This error can be caused by faulty hardware components, outdated drivers, or issues with system files. Identifying and addressing the root cause is essential for fixing this problem.

Step 1: Check for Hardware Issues

1.1 Inspect Physical Components

Start by inspecting the physical components of your computer. Ensure that all components are properly seated and connected. This includes:

RAM modules: Check if the RAM is securely inserted in its slot. Consider reseating the RAM sticks.
Hard drives: Ensure that all cables connecting the hard drive to the motherboard are secure.
Graphics card: Verify that the graphics card is properly installed and connected.

1.2 Run Hardware Diagnostics

Most systems come with built-in diagnostic tools. Run these tools to check for hardware issues:

Dell: Press F12 during startup to access diagnostics.
HP: Press Esc and then F2 to open the Hardware Diagnostics menu.
Lenovo: Use the Lenovo Solution Center to run diagnostics.

Alternatively, you can use third-party diagnostic tools like MemTest86 for memory testing or Hard Disk Sentinel for hard drive health monitoring.

Step 2: Update or Reinstall Drivers

2.1 Update Device Drivers

Outdated or corrupted drivers can contribute to error code 0x0000009C. Update your drivers to the latest versions:

Open Device Manager: Press Windows + X and select Device Manager.
Expand each category: Right-click on each device and choose Update Driver.
Search automatically: Select Search automatically for updated driver software.

2.2 Reinstall Drivers

If updating drivers does not resolve the issue, consider reinstalling them:

Uninstall the device: In Device Manager, right-click on the device and select Uninstall device.
Restart your computer: Windows will attempt to reinstall the driver upon reboot.

Step 3: Check for System File Corruption

3.1 Run System File Checker

Corrupted system files can cause various errors. Use the System File Checker tool to repair these files:

Open Command Prompt as Administrator: Press Windows + X and select Command Prompt (Admin) or Windows PowerShell (Admin).
Run SFC command: Type sfc /scannow and press Enter. Wait for the process to complete.

3.2 Use DISM Tool

If SFC does not resolve the issue, use the Deployment Imaging Service and Management Tool (DISM):

Open Command Prompt as Administrator.
Run DISM command: Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.

Step 4: Check and Update BIOS

4.1 Enter BIOS Setup

Sometimes updating the BIOS can resolve hardware compatibility issues:

Restart your computer: During startup, press the key to enter BIOS (commonly F2, F10, DEL, or ESC).
Check current BIOS version: Locate the BIOS version information within the BIOS settings.

4.2 Update BIOS

Visit your motherboard manufacturer’s website to download the latest BIOS update. Follow their instructions carefully to update the BIOS.

Step 5: Test System Stability

5.1 Perform Stress Tests

Stress testing can help identify hardware components that might be causing the error:

CPU Stress Test: Use tools like Prime95 or IntelBurnTest.
GPU Stress Test: Utilize tools such as FurMark.
RAM Test: Run MemTest86.

5.2 Monitor System Temperatures

Overheating can also trigger error code 0x0000009C. Use monitoring tools like HWMonitor or Speccy to check your system’s temperatures and ensure adequate cooling.

Step 6: Check Event Viewer Logs

6.1 Access Event Viewer

Event Viewer can provide detailed information about the error:

Open Event Viewer: Press Windows + R, type eventvwr.msc, and press Enter.
Navigate to Windows Logs: Click on System and look for error entries related to the time of the crash.

6.2 Analyze Error Logs

Identify any recurring errors or warnings that coincide with the 0x0000009C error. This information can help pinpoint the exact cause.

Step 7: Perform a Clean Boot

7.1 Boot into Safe Mode

A clean boot can help determine if background services or startup programs are causing the issue:

Open System Configuration: Press Windows + R, type msconfig, and press Enter.
Select Safe Boot: Go to the Boot tab and select Safe boot. Restart your computer.

7.2 Diagnose in Safe Mode

If the issue does not occur in Safe Mode, it suggests that a third-party application or service might be causing the problem. Disable startup items and services selectively to identify the culprit.

Step 8: Restore System or Reinstall Windows

8.1 System Restore

If the issue persists, use System Restore to revert your system to a previous state:

Open System Restore: Press Windows + R, type rstrui, and press Enter.
Choose a restore point: Follow the prompts to select a restore point before the issue began.

8.2 Reinstall Windows

As a last resort, consider reinstalling Windows:

Backup your data: Ensure all important files are backed up.
Create installation media: Use the Windows Media Creation Tool to create a bootable USB or DVD.
Reinstall Windows: Follow the instructions to perform a clean installation.
