Windows Crashes or Freezes

Windows crashes and freezes can be caused by software conflicts, corrupted system files, overheating, failing hardware, or driver issues. This guide covers the most common causes and solutions for Windows 10 and Windows 11.

Common Symptoms

  • PC freezes randomly
  • Apps stop responding
  • Blue screen errors (BSOD)
  • System restarts without warning
  • Mouse and keyboard become unresponsive
  • Screen locks up during gaming or heavy tasks

1. Restart the PC

Temporary system hangs often clear after a reboot.

  • Restart normally
  • If frozen, hold the power button for 5–10 seconds

2. Check for Overheating

High temperatures can cause freezes and shutdowns.

  • Ensure fans are spinning properly
  • Clean dust from vents and fans
  • Check CPU and GPU temperatures in BIOS or monitoring software

3. Update Windows

Outdated system files can cause instability.

  • Go to Settings → Windows Update
  • Install all available updates

4. Update Drivers

Faulty or outdated drivers are a major cause of crashes.

  • Open Device Manager
  • Look for devices with warning icons
  • Update graphics, chipset, and storage drivers

5. Run System File Checker

Fixes corrupted or missing system files.

  • Open Command Prompt as Administrator
  • Run:
sfc /scannow

6. Run DISM Repair

Repairs deeper Windows image corruption.

  • Run the following commands:
dism /online /cleanup-image /checkhealth
dism /online /cleanup-image /scanhealth
dism /online /cleanup-image /restorehealth

7. Check for Faulty RAM

Bad memory can cause freezes, crashes, and BSODs.

  • Run Windows Memory Diagnostic
  • Test RAM sticks individually if needed

8. Check the Hard Drive or SSD

Failing drives can cause system hangs and crashes.

  • Run:
chkdsk C: /f /r

9. Scan for Malware

Malicious software can cause instability and freezing.

  • Run a full scan with Windows Security
  • Use offline scan if needed

10. Reset Windows (Last Resort)

If crashes continue, a reset may be required.

  • Select Reset this PC from Recovery options
  • Choose Keep my files when possible
