Kelvin

 

A Blue Screen of Death (BSOD) or "stop error" in Windows usually indicates a critical system issue that causes your computer to crash. Here's how to diagnose and fix it:

✅ Step-by-Step Guide to Fix a Blue Screen Error

1. Note the Error Code

When the BSOD appears, you'll usually see a code like CRITICAL_PROCESS_DIED, IRQL_NOT_LESS_OR_EQUAL, or 0x0000007E. This can help pinpoint the problem.

You can also find the details later:

  • Go to Event Viewer: Windows Logs > System
  • Use BlueScreenView (free tool) to analyze dump files at C:\Windows\Minidump

2. Restart Your Computer in Safe Mode

Boot into Safe Mode:

  • Hold Shift while clicking Restart
  • Go to: Troubleshoot > Advanced options > Startup Settings > Restart > Press F4 for Safe Mode

3. Check for Hardware Issues

  • RAM: Use Windows Memory Diagnostic (mdsched.exe)
  • Hard Drive: Run chkdsk /f /r in Command Prompt (admin)
  • Disconnect external devices (USB drives, peripherals)

4. Update or Roll Back Drivers

  • Go to Device Manager
  •  Right-click suspect devices > Update driver
  • Or roll back recently installed drivers

Common troublemakers: graphics cards, network adapters, storage controllers

5. Scan for Malware

Use:

  • Windows Defender Offline Scan
  • Or tools like Malwarebytes

6. Check Windows Updates

Outdated or buggy updates can cause BSODs.

  • Go to Settings > Update & Security > Windows Update
  • Install or uninstall recent updates (View update history)

7. System Restore

If the BSOD started recently:

  • Go to: Control Panel > Recovery > Open System Restore
  • Pick a restore point from before the problem started

8. Reset or Reinstall Windows

If nothing else works:

  • Reset PC: Settings > Update & Security > Recovery > Reset this PC
  • Or do a clean install from a USB using the Media Creation Tool
