A sudden Windows crash can be frustrating, especially when you’re in the middle of important work. Whether your PC shows a blue screen of death (BSOD), keeps restarting, or freezes randomly, you need a quick and effective fix. In this guide, we’ll walk you through the possible reasons why Windows crashes and how you can fix Windows crash issues at home.
Why Does Windows Crash?
Before jumping into the fixes, let’s understand the common causes behind Windows crashes:
✅ Corrupt System Files – Missing or damaged Windows files can lead to unexpected crashes.
✅ Driver Issues – Outdated or faulty drivers can cause compatibility problems.
✅ Overheating – Excessive heat can force your PC to shut down unexpectedly.
✅ Malware or Virus Attacks – Harmful software can corrupt system files and cause crashes.
✅ Hardware Failures – A failing hard drive, RAM, or motherboard may lead to system instability.
✅ Software Conflicts – Incompatible programs or third-party apps can trigger crashes.
Now that we know the causes, let’s get to the solutions!
How to Fix Windows Crash Issues?
1. Restart Your PC in Safe Mode
If Windows keeps crashing, boot into Safe Mode to troubleshoot:
1️⃣ Turn off your PC and turn it back on.
2️⃣ Press F8 or Shift + F8 repeatedly while booting.
3️⃣ Select Safe Mode from the options.
4️⃣ Once in Safe Mode, check for faulty drivers or recently installed software.
2. Run a System File Checker (SFC Scan)
Windows has a built-in tool to scan and repair corrupt system files:
🔹 Type cmd in the Windows search bar and open Command Prompt (Admin).
🔹 Type: sfc /scannow and hit Enter.
🔹 Wait for the scan to complete and restart your PC.
3. Update Your Drivers
Outdated drivers can cause serious issues. To update your drivers:
✔️ Open Device Manager by pressing Win + X.
✔️ Expand the categories and right-click on a device (e.g., Display Adapters).
✔️ Select Update Driver and follow the prompts.
4. Check for Windows Updates
Microsoft regularly releases updates to fix bugs and improve security. To check for updates:
🔸 Go to Settings > Update & Security > Windows Update.
🔸 Click Check for Updates and install any available updates.
5. Scan for Viruses & Malware
Malware infections can cause frequent Windows crashes. Run a full system scan using:
🔹 Windows Defender (built-in antivirus).
🔹 Third-party antivirus software (like Avast, Norton, or Malwarebytes).
6. Check for Overheating Issues
If your PC overheats, it may crash to prevent hardware damage.
💨 Clean dust from the CPU fan and vents.
🌡️ Use HWMonitor or Core Temp to check CPU temperature.
🔧 Apply thermal paste to the processor if needed.
7. Test Your RAM & Hard Drive
Faulty RAM or a failing hard drive can cause blue screen errors and crashes.
🛠️ Use Windows Memory Diagnostic Tool to test RAM:
1️⃣ Type mdsched.exe in the search bar and press Enter.
2️⃣ Select Restart now and check for problems.
🛠️ Check hard drive health with CHKDSK:
1️⃣ Open Command Prompt (Admin).
2️⃣ Type: chkdsk /f /r and press Enter.
3️⃣ Restart your PC to let Windows scan and repair errors.
8. Uninstall Problematic Software
If your PC started crashing after installing a new app, uninstall it:
🖥️ Go to Control Panel > Programs & Features.
🗑️ Select the recently installed software and click Uninstall.
🔄 Restart your PC and check if the issue is resolved.
9. Perform a System Restore
If nothing works, try System Restore to roll back to a stable state:
🔹 Type System Restore in the search bar.
🔹 Click Create a restore point > System Restore.
🔹 Choose a restore point from before the crashes started.
🔹 Follow the instructions to restore Windows.
10. Reset Windows (Last Resort)
If crashes persist, reset your PC:
🔸 Go to Settings > Update & Security > Recovery.
🔸 Click Reset this PC and choose Keep my files (to save data) or Remove everything (for a fresh install).
