Check for overheating by monitoring temperatures with tools like HWMonitor, clean dust from fans and vents, ensure proper ventilation, and verify fan operation. 2. Update or roll back drivers via Device Manager, especially graphics drivers from official websites, and install pending Windows updates. 3. Scan for malware using Windows Security or trusted antivirus software, then run sfc /scannow in Command Prompt as admin, followed by DISM /Online /Cleanup-Image /RestoreHealth if needed. 4. Check disk health using chkdsk C: /f /r and tools like CrystalDiskInfo, and test RAM using Windows Memory Diagnostic. 5. Adjust power settings to High Performance, set processor state to 5–10% minimum and 100% maximum, disable PCI Express power management, and disable unnecessary startup apps. 6. Boot into Safe Mode by restarting with Shift, selecting Startup Settings, and pressing F4, then test for freezes to determine if the issue is software-related. 7. As a last resort, reset Windows 11 via Settings → System → Recovery → Reset this PC while choosing "Keep my files" after backing up important data. Most freezing issues can be resolved by systematically addressing overheating, driver, malware, hardware, and configuration problems, with a full system reset recommended only when other steps fail.

If your Windows 11 computer keeps freezing, it can be frustrating and disruptive. Freezing can stem from hardware, software, or system configuration issues. Here’s a step-by-step guide to help you diagnose and fix the problem.

1. Check for Overheating

Overheating is a common cause of system freezes, especially during heavy usage.

• Monitor temperatures: Use tools like HWMonitor, Core Temp, or SpeedFan to check CPU and GPU temperatures.
  • Normal idle: 30–50°C
  • Under load: below 85°C (varies by model)
• Clean your PC: Dust buildup can block airflow. Use compressed air to clean fans and vents.
• Ensure proper ventilation: Don’t use the laptop on soft surfaces like beds or couches.
• Check fan operation: Listen for unusual noises or fans not spinning.

If your system overheats, consider repasting the CPU/GPU (for advanced users) or using a cooling pad.

2. Update or Roll Back Drivers

Outdated, corrupt, or incompatible drivers—especially graphics and chipset drivers—can cause freezes.

• Update drivers:
  • Press Win X → Device Manager.
  • Look for devices with a yellow warning icon.
  • Right-click and select "Update driver."
• Update graphics drivers:
  • Go to the manufacturer’s website (NVIDIA, AMD, Intel) for the latest version.
  • Avoid using third-party driver updaters.
• Roll back problematic drivers:
  • If the freezing started after a driver update, go to Device Manager → right-click the driver → "Properties" → "Roll Back Driver."

Also, ensure your system is up to date:

• Go to Settings → Windows Update → install all pending updates.

3. Scan for Malware and System Files

Malware or corrupted system files can cause instability.

• Run a malware scan:
  • Use Windows Security (Defender) or a trusted third-party antivirus.
  • Perform a full system scan.
• Run System File Checker (SFC):
  • Open Command Prompt as admin (search for "cmd", right-click → "Run as administrator").
  • Type: sfc /scannow
  • Let it repair any corrupted system files.
• Run DISM tool (if SFC fails):
  • In Command Prompt (admin), run:

    DISM /Online /Cleanup-Image /RestoreHealth

  • Then run sfc /scannow again.

4. Check for Disk and Memory Issues

Failing hardware, especially storage and RAM, often causes freezes.

• Check your hard drive/SSD health:
  • Use built-in tool: Open Command Prompt and run:

    chkdsk C: /f /r

    (Approve to run on next restart if needed.)

  • Use tools like CrystalDiskInfo to monitor drive health (look for "Caution" or "Bad" status).
• Test your RAM:
  • Search for "Windows Memory Diagnostic" → run it.
  • It will schedule a test on reboot. Check results after restart.

If hardware issues are detected, consider replacing the faulty component.

5. Adjust Power and Performance Settings

Power plans can sometimes throttle performance or cause instability.

• Go to Control Panel → Power Options.
• Select High performance or Balanced.
• Click "Change plan settings" → "Change advanced power settings".
  • Expand "Processor power management" → set "Minimum processor state" to 5–10% and "Maximum" to 100%.
  • Disable "PCI Express → Link State Power Management".

Also, disable unnecessary startup apps:

• Press Ctrl Shift Esc → Startup tab → disable non-essential apps.

6. Boot into Safe Mode and Test

Safe Mode loads only essential drivers and services. If the system doesn’t freeze in Safe Mode, the issue is likely software-related.

• Restart and hold Shift while clicking "Restart".
• Go to Troubleshoot → Advanced Options → Startup Settings → Restart.
• Press F4 to enable Safe Mode.
• Use the system and see if it still freezes.

If it runs fine in Safe Mode:

• Uninstall recently installed software.
• Check for conflicts in background apps.
• Consider a clean boot (via msconfig) to isolate the culprit.

7. Consider a System Reset (Last Resort)

If all else fails, reset Windows 11:

• Go to Settings → System → Recovery → Reset this PC.
• Choose "Keep my files" to reinstall Windows without losing personal data.
• This removes apps and settings that might be causing issues.

Make sure to back up important data before proceeding.

Freezing issues in Windows 11 are usually solvable with methodical troubleshooting. Start with the most common causes—overheating, drivers, and malware—then work your way toward hardware and system resets. Most cases can be resolved without professional help.
