This article provides guidance on diagnosing and resolving some of the most frequently encountered errors within the Windows operating system. From boot failures to application crashes, we'll walk you through systematic approaches to get your system back on track.
Error Code: 0x80070002
"The system cannot find the file specified." This error commonly occurs during Windows Update or when installing new software.
Troubleshooting Steps:
- Check Disk Space: Ensure you have sufficient free space on your system drive (usually C:). Insufficient space can prevent downloads and installations.
- Run System File Checker (SFC): Open Command Prompt as administrator and type
sfc /scannow
. This tool scans for and repairs corrupted system files. - Clear Windows Update Cache: Stop the Windows Update service, delete the contents of the
C:\Windows\SoftwareDistribution\Download
folder, and then restart the Windows Update service. - Run the Windows Update Troubleshooter: Navigate to Settings > Update & Security > Troubleshoot > Additional troubleshooters and run the Windows Update troubleshooter.
Error: Blue Screen of Death (BSOD) - PAGE_FAULT_IN_NONPAGED_AREA
This error indicates that a process tried to access a memory address that it shouldn't have. It's often related to hardware issues or faulty drivers.
Troubleshooting Steps:
- Note the Error Message: Pay attention to any specific file names mentioned on the BSOD screen, as they can provide clues.
- Check Recently Installed Hardware/Software: If the issue started after a new installation, try removing or uninstalling it.
- Update Drivers: Ensure all your hardware drivers (graphics, network, audio, etc.) are up-to-date. Visit your hardware manufacturer's website.
- Run Memory Diagnostic Tool: Search for "Windows Memory Diagnostic" in the Start menu and run the tool to check for RAM issues.
- Check for Disk Errors: Open Command Prompt as administrator and run
chkdsk C: /f /r
. This will check and repair disk errors (requires a restart).
Error: Application Crashes or Freezes
Applications may unexpectedly close or become unresponsive. This can be caused by software conflicts, corrupted application files, or system resource limitations.
Troubleshooting Steps:
- Restart the Application: A simple restart can often resolve temporary glitches.
- Restart Your Computer: This clears temporary system issues and frees up resources.
- Update the Application: Check for and install any available updates for the problematic application.
- Run the Application in Compatibility Mode: Right-click the application's executable file, select Properties, go to the Compatibility tab, and try running it in compatibility mode for an older version of Windows.
- Reinstall the Application: If issues persist, uninstall the application completely, then download and install the latest version.
- Check for Windows Updates: Ensure your Windows operating system is fully updated.
Error: "Windows is not genuine" message
This message appears when Windows detects that your copy is not genuine or has been tampered with.
Troubleshooting Steps:
- Verify Your Product Key: Ensure you are using a valid Windows product key. If you purchased a new PC, the key is often pre-installed.
- Activate Windows Online: Go to Settings > Update & Security > Activation and try to activate Windows online.
- Troubleshoot Activation: If online activation fails, use the built-in activation troubleshooter.
- Contact Microsoft Support: If you suspect a licensing issue or cannot resolve it through the above steps, contact Microsoft Support for further assistance.
