Tip: In cases where the computer is unresponsive to Task Manager or Force Quit commands, jump ahead to Step 3 to learn how to perform a hard reset.

1. Force Close Frozen Applications

The easiest way to resolve a frozen screen is by closing unresponsive applications.

• On Windows devices, press Ctrl + Alt + Delete or Ctrl + Shift + Esc to open Task Manager. You can also right-click the task bar and select Task Manager. Select the unresponsive app and click End Task. Alternatively, you can press Alt + F4 to close the current window or application.

• On Mac devices, press Command + Option + Esc to open the Force Quit menu, then select the unresponsive app and click Force Quit. If that doesn’t work, open Activity Monitor (Finder > Applications > Utilities) and close the app from there.

Tip: Uninstall applications that regularly cause your computer to freeze for improved stability.

 

2. Restart File Explorer on Windows

For Windows users, restarting File Explorer (formerly Windows Explorer) can often help. Open Task Manager, click More Details, then under the Processes tab, scroll to File Explorer, select it, and click End Task. This will refresh your system without needing a full restart.

 

3. Perform a Hard Reset

If your computer is completely frozen and unresponsive to the keyboard shortcuts:

• On Windows, press and hold the power button until the system shuts down. Wait a few seconds, then restart.
• On Mac, press Command + Control + Power simultaneously until the computer powers off. Release the buttons, wait a few seconds, and press the power button again to reboot.

If the system continues to freeze, try starting the device in Safe Mode (press F8 on Windows during startup).

 

4. Check Hardware Connections

Make sure that all hardware components, such as the keyboard, mouse, and cables, are connected properly. If you're experiencing recurring issues, check your device's fan to ensure it's functioning. Overheating can cause freezes. For laptops, also monitor the health of your battery.

Tip: Consider checking your device's RAM and general system health—older devices or insufficient RAM can contribute to freezing.

 

5. Check for Software Updates

Outdated software is a common cause of frozen screens. Regularly check for updates by going to your device settings. Contact the IT department if you need assistance.

 

6. Uninstall Unused Programs

Lack of storage space can cause your computer to freeze. To free up space, uninstall unnecessary programs. On Windows, go to the Control Panel > Programs and Features. On Mac, go to Applications and remove unused software.

 

 

7. Scan for Malware or Viruses

Malware or viruses can also be responsible for frozen screens. Ensure your system is regularly scanned using Windows Defender. You can also reach out to IT for assistance if needed.

 

 

8. Reset PRAM or NVRAM (Mac Only)

For Mac users experiencing issues such as unresponsive controls or display problems, resetting PRAM or NVRAM may help. To do this, shut down your Mac, turn it back on, and immediately press Option + Command + P + R. Release the keys after 20 seconds, then allow the computer to restart.

 

9. Repair Disk Permissions (Mac Only)

Improper disk permissions can cause freezing issues. To repair disk permissions on a Mac, open Disk Utility by pressing Shift + Command + U. Select the hard drive, click First Aid, and let the tool fix any issues. It's recommended to repair disk permissions once or twice a year.

10. Clear Cache and Temporary Files

Temporary files and cached data can slow down your system. Regularly clear your computer’s cache to free up space. The settings menu in Windows 11 has a built-in tool for clearing the cache. It lets you delete the same files that the older Disk Cleanup tool does, but with a modern look. Use these steps for major browsers:

• To begin, open Settings and go to System > Storage > Temporary Files.

•  

  In the Temporary Files menu, you'll see several types of files you can delete. Check the boxes for the categories you want cleared, then click the "Remove Files" button.

• Windows will ask if you're sure you want to delete those files. If you are sure, click "Continue," and your cache will be cleared.

 

Common Causes of a Frozen Computer

Several issues can cause your computer to freeze, including:

• Hardware failures: Faulty hard drives, memory, or overheating.
• Software glitches: Outdated or incompatible applications.
• Low storage: Full hard drives or insufficient RAM.
• Driver issues: Corrupted or malfunctioning drivers.
• Malware/viruses: Infected systems may become unresponsive.

 

If your device continues to freeze after following these steps, contact the Health Genesis IT help desk for further assistance.
