  2. Open Device Manager by right-clicking Computer and selecting Manage > Device Manager.
  3. Expand nodes to locate the device with driver issues. You may see a warning sign or errors.
  4. Right-click the device and select Update Driver Software.
  5. Select “Search automatically for updated driver software” to find and install an updated driver.
  6. If updates are not available, rollback the driver. Right-click the device, select Properties > Driver tab, and click Roll Back Driver.
  7. You can also uninstall the faulty driver completely, then reboot so Windows reinstalls default drivers.
  8. Update other outdated drivers as needed.
  9. Reboot and see if the error persists. Update or rollback additional drivers one by one until resolved.

This process helps eliminate bad drivers as the source of the error. Be sure to keep your drivers updated, especially for critical components like your video card, storage drives, and motherboard.

How to Fix System File Corruption

If a corrupted Windows system file is causing the error, using System File Checker can scan and restore corrupted files:

  1. Type cmd in the Windows search bar.
  2. Right-click Command Prompt and select Run as administrator.
  3. Type sfc /scannow and hit Enter to run the scan.
  4. System File Checker will scan Windows files and repair any damage found.
  5. Restarts may be required to fully apply repairs.
  6. Run additional scans until no corrupted files are found.

This scans and restores important system files that may have become corrupted or damaged. If files cannot be repaired, your Windows installation media or recovery image can provide working copies.

How to Use Windows Startup Repair

Startup Repair is another handy Windows recovery tool that can fix issues like:

  • Corrupted or missing system files
  • Damaged boot configuration settings
  • Boot errors that crash Windows during launch

To run Startup Repair:

  1. Access the Windows Advanced Boot Options menu.
  2. Select the Windows installation drive, usually C:\, and click Repair Your Computer.
  3. Choose Troubleshoot > Advanced Options > Startup Repair.
  4. Startup Repair will scan and automatically attempt repairs.
  5. If it finds and fixes issues, click Restart when prompted.

Startup Repair helps identify and restore damaged system files and settings needed to load Windows properly on boot. This can resolve many causes behind the “A problem has been detected” error.

How to Resolve Registry Errors

The Windows registry stores system configuration settings that could get corrupted and cause the critical error. Use Registry Editor to fix issues:

  1. Type regedit in the Windows search bar and select Registry Editor.
  2. Navigate to problem registry keys identified in memory dump logs.
  3. Right-click damaged keys and select Delete to remove corrupt entries.
