  5. Upgrade cooling system with more fans or liquid cooling

Keeping your computer’s hardware cool will help avoid heat-related freezing issues. Aim to keep the CPU below 70°C and GPU below 80°C under load for optimal stability.

Check for Faulty Hardware

In some cases, failing or defective hardware components could be the root cause behind random system freezes. Try these hardware troubleshooting steps:

  • Open Windows Memory Diagnostic to scan for RAM issues
  • Run chkdsk in Command Prompt to check for hard drive errors
  • Test hardware components individually by swapping parts
  • Listen for odd noises which could indicate a failing fan or hard drive
  • Monitor system logs for hardware events around time of crashes

If you have recently installed new hardware, a faulty component could be to blame. Isolating components through substitution or external testing can reveal failing hardware causing freezes.

Uninstall Conflicting Software

Incompatible or buggy third party software can also be a source of random freezes and crashes in Windows 10. Try troubleshooting software issues with these steps:

  1. Boot into Safe Mode – Does freezing persist without other software?
  2. Uninstall recently added antivirus, drivers or other software
  3. Check for updates to installed software
  4. Use System Restore to roll back before software was installed
  5. Reset Windows 10 while keeping files and programs

By methodically removing or rolling back software changes, you can isolate any third party apps or drivers causing conflict and instability.

Examine System Files

Corrupted Windows system files could potentially lead to freezing issues. Analyze system file integrity with these steps:

  • Run SFC /scannow in Command Prompt to check for errors
  • Open Command Prompt as admin and run DISM scan:
    DISM /Online /Cleanup-Image /RestoreHealth
  • Reset or reinstall Windows 10 as a last resort

Scanning for discrepancies and restoring corrupted data in system files may resolve unexpected freezing behavior.

Adjust Visual Effects

Graphical flair like animations can sometimes strain resources and cause system hangs. Reduce visual effects:

  1. Go to Advanced system settings > Performance Settings
  2. Adjust for best performance
  3. Disable transparency effects

If your system resources are being taxed, scaling back on visual effects and animations can help prevent freezing issues.

Run Antivirus Scan

Although less common, malware and viruses can sometimes cause Windows 10 to freeze and crash. Scan your system:

  • Run a Quick Scan in Windows Security
  • Download Malwarebytes for a second opinion scan
  • Check for suspicious programs under Processes in Task Manager
  • Monitor real-time protection from your antivirus software

Catching and removing any potential infections could prevent further freezing events.

Conclusion

Random system freezes and hangs can stem from a wide range of software and hardware issues. By methodically addressing each potential cause, you should be able to identify and correct the problem. Don’t hesitate to reset Windows 10 or reinstall from scratch if simpler fixes are unsuccessful.

Some key steps include updating drivers, adjusting power settings, cleaning your PC, isolating faulty hardware or software, scanning and repairing system files, reducing animations, and checking for malware. With the right combination of software tweaks and hardware maintenance, you can stop frustrating freezes and get smooth sailing performance.
