Whether it's your personal device or work laptop, a frozen computer screen often occurs at the most inconvenient times. Luckily, there are multiple solutions available to help you reduce downtime and get back to work quickly when your computer freezes.
10 Ways to Fix a Frozen Computer Screen
Try these 10 steps to fix a frozen computer, from simple restarts to more advanced troubleshooting techniques. If your computer is so frozen that you can't open Task Manager, Force Quit, or restart File Explorer, you may need to perform a hard restart.
Force Close Frozen Apps
The first and simplest step is to close the frozen applications. On a Windows device, press Control + Alt + Delete or Control + Shift + Escape to open the Task Manager. Select the unresponsive app and choose "End Task." Alternatively, pressing Alt + F4 can close the active window or application quickly.
On a Mac, press Command + Option + Escape to open the Force Quit window, select the unresponsive app, and click "Force Quit." If that doesn't work, try force-quitting other apps. Another option is to use the Activity Monitor (Finder > Applications > Utilities) to close unresponsive apps.
Tip: Consider uninstalling apps that frequently cause your computer to freeze on both Windows and Mac devices.
Restart File Explorer on Windows
Windows users can also try restarting File Explorer (previously called Windows Explorer). Open Task Manager, click "More Details," find the Processes tab, locate File Explorer, and select "End Task."
Restart the Frozen Computer
If your Windows computer is completely unresponsive and Ctrl + Alt + Del doesn't work, perform a hard reset by holding the power button until the computer shuts down. Wait a few seconds, then turn it back on. If the freezing persists, try rebooting in safe mode by repeatedly pressing the F8 key.
For Mac users, hold down Command + Control + Power until the computer shuts down, then wait a few seconds before turning it back on.
Check Hardware
Ensure all hardware is correctly connected. Problems like a dead battery, frozen mouse, or disconnected cables can cause your computer to freeze. Also, check if the computer's fan is working properly, as overheating can lead to unresponsiveness. Laptop users should also check battery health, and if the computer is old or has limited RAM, it might be time to consider a replacement.
Check for Updates
Freezing can result from outdated software or missed updates. Go to your computer's settings and install any available updates, then restart the device. If your organization uses Mobile Device Management (MDM), this can be done remotely by IT.
Uninstall Unused Programs
If your computer frequently freezes, it might be due to insufficient storage space. Uninstall any programs you no longer use through the Control Panel (Windows) or Applications (Mac) to free up space.
Scan for Malware and Viruses
Malware or viruses could be causing the freeze. Run a scan using your computer's built-in security tools or third-party software. Ensure that up-to-date antivirus software is installed and regular scans are conducted.
Restart PRAM or NVRAM on Macs
If your Mac has issues with display resolution, volume controls, or mouse behavior, try resetting PRAM or NVRAM. Shut down your Mac, turn it back on, and immediately press Option + Command + P + R. Hold these keys for 20 seconds before releasing.
Repair Disk Permissions on Macs
Disk permissions can cause freezing if they become corrupted. To repair permissions, open Disk Utility (Finder > Applications > Utilities), select your hard drive, and click "First Aid."
Tip: It's a good practice to repair disk permissions once or twice a year for maintenance.
Clear Cache and Temporary Files
Accumulated cache and temporary files can slow down your computer and cause freezing. Clear these files through your browser settings to improve performance. However, keep in mind that clearing cache and cookies may log you out of websites.
Common Causes of Computer Freezing
- Hardware Issues: Damaged hard drives, memory cards, and connections, or overheating.
- Software Issues: Outdated or incompatible software.
- Storage Issues: Running out of storage space.
- Driver Issues: Malfunctioning or corrupted drivers.
- Malware: Infections that compromise device performance.
