Step-by-Step Guide: How to Find Out Why Your Computer Crashed on Windows 11

1. Check Reliability Monitor

Reliability Monitor is like a health report card for your PC.

Steps:

1. Press Win + S and search Reliability Monitor.

2. Open View reliability history.

3. Look for red X icons (critical events).

4. Click a crash entry to see details (e.g., application failure, hardware error).

💡 Tip: This gives you a timeline of crashes, making patterns easier to spot.

2. Use Event Viewer to Analyze System Logs

Event Viewer records everything that happens on your PC, including crashes.

Steps:

1. Press Win + X → Select Event Viewer.

2. Navigate to Windows Logs > System.

3. Look for errors around the time of the crash (marked in red).

4. Pay attention to Event ID and Source (e.g., Kernel-Power, BugCheck).

👉 Example: Event ID 41 (Kernel-Power) often means your PC restarted unexpectedly due to power failure or overheating.

3. Check Blue Screen of Death (BSOD) Error Codes

If your PC showed a Blue Screen, it displayed a stop code.

Common ones include:

• IRQL_NOT_LESS_OR_EQUAL → Faulty drivers.

• MEMORY_MANAGEMENT → RAM issues.

• CRITICAL_PROCESS_DIED → System file corruption.

Steps to review BSOD logs:

1. Press Win + R, type msinfo32, and press Enter.

2. Check Software Environment > Windows Error Reporting for crash logs.

3. Or use Event Viewer > System > BugCheck entries.

4. Analyze Dump Files (Advanced)

Windows creates a dump file when it crashes.

Steps:

1. Navigate to C:\Windows\Minidump.

2. Open the .dmp file with tools like WinDbg or BlueScreenView.

3. Look for the driver or system file that caused the crash.

⚠️ Requires some technical knowledge, but it’s very precise.

7. Test for Overheating

Overheating can force sudden shutdowns.

Steps:

1. Use free tools like HWMonitor or Core Temp.

2. Check CPU/GPU temperatures (should generally be below 85°C under load).

3. Clean fans and ensure proper ventilation.
