Windows 10 Keeps Freezing? 10 Ways to Fix a Frozen or Unresponsive PC (2026)

Does your Windows 10 PC keep freezing, hanging, or apps not responding after startup? You may notice the mouse cursor stops moving, programs stop responding, the screen freezes completely, or the computer locks up and requires a forced restart.

Windows 10 freezing issues can occur for many reasons. In some cases, a background process may be using excessive system resources. In others, outdated drivers, corrupted system files, insufficient storage space, malware, or overheating hardware may cause the computer to stop responding. In this guide, we’ll explain why Windows 10 keeps freezing and walk you through the most effective solutions to get your PC running smoothly again.

Why Windows 10 Keeps Freezing

Windows 10 can freeze when the system runs out of available resources or encounters a hardware or software problem. In some cases, the computer may become unresponsive for a few seconds before recovering, while in others it may completely lock up and require a restart.

Some of the most common causes include:

• Too Many Background Programs: Excessive CPU, RAM, or disk usage can make Windows unresponsive.
• Outdated or Corrupted Drivers: Faulty drivers can cause conflicts that lead to freezing and crashes.
• Corrupted System Files: Damaged Windows files can affect system stability and performance.
• Insufficient Storage Space: A nearly full system drive can slow down Windows and cause freezing.
• Malware or Unwanted Software: Malicious programs may consume resources and interfere with normal operation.
• Overheating Hardware: Excessive heat can cause the system to freeze or shut down unexpectedly.
• Problematic Updates or Applications: Recently installed updates or software can sometimes create compatibility issues.
• Failing Hardware: Faulty RAM, HDDs, or SSDs can trigger random system freezes.

Fix 1: Check Resource Usage in Task Manager

One of the most common reasons Windows 10 freezes is excessive CPU, memory, or disk usage. If a program or background process is consuming too many system resources, your computer may become slow, unresponsive, or completely freeze.

Task Manager can help identify which applications are causing the problem.

To check resource usage:

1. Press Ctrl + Shift + Esc to open Task Manager.
2. In the Processes tab, click CPU, Memory, or Disk to sort resource usage.
3. Look for applications or processes using unusually high resources.
4. Select unnecessary programs and click End task.
5. Close apps you are not currently using.
6. Monitor your system for a few minutes to see if performance improves.

If a particular application repeatedly causes high CPU, memory, or disk usage, consider updating, reinstalling, or removing it. Many Windows freezing issues can be resolved simply by identifying and stopping a resource-hungry application.

Fix 2: Restart Windows Explorer

Sometimes Windows Explorer (File Explorer) may stop responding, making the desktop, taskbar, Start menu, or File Explorer window appear frozen. Restarting the Explorer process can often restore normal functionality without requiring a full system restart.

To restart Windows Explorer:

1. Press Ctrl + Shift + Esc to open Task Manager.
2. In the Processes tab, locate Windows Explorer.
3. Right-click Windows Explorer and select Restart.
4. Wait a few seconds while the desktop and taskbar reload.

If Windows Explorer is not listed:

1. Click File > Run new task.
2. Type explorer.exe and click OK.

Once the process restarts, check whether the freezing issue has been resolved. This fix is particularly useful if only the desktop, taskbar, or File Explorer becomes unresponsive while other applications continue to work.

Fix 3: Disconnect External Devices

Faulty or incompatible external devices can sometimes cause Windows 10 to freeze. USB drives, printers, webcams, external hard drives, docking stations, and other peripherals may create hardware conflicts or driver issues that affect system stability.

Disconnecting unnecessary devices can help determine whether one of them is causing the problem.

To test for hardware conflicts:

1. Shut down your computer.
2. Disconnect all non-essential external devices, including:
   • USB flash drives
   • External hard drives
   • Printers
   • Webcams
   • USB hubs
   • Other accessories
3. Restart your PC.
4. Use the computer for a while and check if it still freezes.

If the freezing stops, reconnect the devices one at a time until you identify the problematic hardware. Once you find the device causing the issue, try updating its driver, reconnecting it to a different USB port, or replacing the hardware if necessary.

Fix 4: Update Device Drivers

Outdated, corrupted, or incompatible device drivers can cause Windows 10 to freeze, crash, or become unstable. Graphics, chipset, storage, and network drivers are particularly important because they directly affect how Windows communicates with your hardware.

Updating your drivers can resolve compatibility issues and improve system stability.

To update device drivers:

1. Right-click the Start button and select Device Manager.
2. Expand the category for the device you want to update.
3. Right-click the device and select Update driver.
4. Choose Search automatically for drivers.
5. Follow the on-screen instructions to install available updates.
6. Restart your computer after updating the drivers.

For the best results, download the latest drivers directly from your computer or motherboard manufacturer’s support website, especially for graphics, chipset, and storage devices.

If the freezing started after a recent driver update, consider rolling back the driver to the previous version and check whether the issue is resolved.

Fix 5: Free Up Disk Space

A lack of free storage space can cause Windows 10 to slow down, hang, or freeze, especially when the operating system cannot create temporary files or manage virtual memory efficiently. This problem is more common on systems with small SSDs or nearly full hard drives.

Freeing up storage space can improve system responsiveness and stability.

To free up disk space:

1. Press Windows + I to open Settings.
2. Go to System > Storage.
3. Click Temporary files.
4. Select unnecessary files such as temporary files, recycle bin items, and update cleanup files.
5. Click Remove files.
6. Delete large files or uninstall applications you no longer use.

You can also move photos, videos, and other large files to an external drive or cloud storage service.

For best performance, try to keep at least 15–20% of your system drive free. Once you’ve cleaned up storage, restart your PC and check whether the freezing issue improves.

Fix 6: Scan for Malware and Unwanted Software

Malware, adware, and potentially unwanted programs can consume CPU, memory, and disk resources in the background, causing Windows 10 to freeze, hang, or become unresponsive.

Running a full malware scan can help identify and remove malicious software affecting system performance.

To scan your PC:

• Press Windows + I to open Settings.
• Go to Update & Security > Windows Security.
• Click Virus & threat protection.
• Select Scan options then Choose Full scan.
• Click Scan now and wait for the scan to complete.

If your PC started freezing after installing new software, browser extensions, or unknown applications, consider uninstalling those programs as well.

Removing malware and unwanted software can often restore normal system responsiveness and prevent random freezes.

Fix 7: Run SFC and DISM to Repair System Files

Corrupted Windows system files can cause random freezes, crashes, and stability issues. If essential system components are damaged, Windows may stop responding or become unstable during normal use.

Windows includes built-in tools called SFC (System File Checker) and DISM that can scan for and repair corrupted system files.

To run SFC:

1. Right-click Start and select Windows Terminal (Admin) or Command Prompt (Admin).
2. Type the following command and press Enter: sfc /scannow
3. Wait for the scan to complete.
4. Restart your computer if repairs are made.

If the issue persists, run DISM:

1. Open Windows Terminal (Admin) again.
2. Enter the following command: DISM /Online /Cleanup-Image /RestoreHealth
3. Wait for the process to finish.
4. Restart your PC.

These tools can repair damaged Windows files and often resolve freezing problems caused by system corruption.

Fix 8: Check for Overheating

Overheating is a common cause of random freezing, especially on older laptops and desktop PCs. When the CPU or GPU reaches high temperatures, the system may slow down, freeze, or shut down unexpectedly to prevent hardware damage.

If your computer freezes while gaming, watching videos, or performing demanding tasks, overheating may be the cause.

To reduce overheating:

1. Make sure the air vents are not blocked by dust or debris.
2. Clean the cooling vents and fans using compressed air.
3. Place laptops on a hard, flat surface to improve airflow.
4. Avoid using the computer in very hot environments.
