Windows 10 Not Responding? 9 Ways to Fix a Frozen PC Without Losing Data (2026)

Has your Windows 10 computer suddenly stopped responding? You may be unable to click anything, applications may freeze, the screen may become stuck, or Windows may display a “Not Responding” message when trying to use a program. This issue is usually caused by excessive resource usage, faulty drivers, corrupted system files, failing hardware, or software conflicts. Fortunately, most of these problems can be fixed without reinstalling Windows or losing your personal files.

In this guide, we’ll explain why Windows 10 stops responding and walk you through the most effective solutions to restore system stability and get your computer working normally again.

Why Windows 10 Stops Responding

Windows 10 may stop responding when a program, driver, or system process becomes stuck and is unable to complete its task. When this happens, applications may freeze, the screen may become unresponsive, or Windows may display a “Not Responding” message.

In some cases, the issue is temporary, and Windows recovers automatically after a few moments. However, recurring freezes usually indicate an underlying software or hardware problem that needs attention.

Some of the most common causes include:

• High CPU, Memory, or Disk Usage: Resource-intensive programs can overwhelm the system and cause it to become unresponsive.
• Corrupted System Files: Damaged Windows files can affect system stability and cause applications to stop responding.
• Outdated or Faulty Drivers: Driver conflicts can prevent Windows and hardware from communicating properly.
• Software Conflicts: Recently installed applications or background programs may interfere with normal system operation.
• Insufficient Storage Space: A nearly full system drive can impact Windows performance and responsiveness.
• Malware or Unwanted Programs: Malicious software can consume system resources and cause freezing issues.
• Faulty RAM or Storage Drives: Hardware issues can cause random hangs, crashes, and unresponsive applications.

Fix 1: Wait for Windows to Recover

When Windows 10 stops responding, it’s tempting to immediately force a restart. However, the system may simply be busy processing a task, installing updates, loading a large file, or handling a resource-intensive application.

If the hard drive activity light is blinking or you can still move the mouse cursor, Windows may recover on its own after a few minutes.

Before taking further action:

1. Wait 2–5 minutes to see if Windows becomes responsive again.
2. Avoid repeatedly clicking buttons or opening additional programs.
3. If an application displays a “Not Responding” message, give it time to complete its current task.
4. Check whether the mouse cursor can still move or whether keyboard shortcuts respond.

If Windows recovers, save your work and close unnecessary applications that may be causing the problem.

If the system remains frozen after several minutes, continue with the next troubleshooting method.

Fix 2: Close Unresponsive Programs

Sometimes Windows itself is working normally, but a specific application has stopped responding. When a program freezes, it can consume system resources and make the entire computer appear unresponsive.

Closing the problematic application can often restore normal system performance without restarting the PC.

To close an unresponsive program:

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Under the Processes tab, look for applications labeled Not Responding or using unusually high CPU, Memory, or Disk resources.
3. Select the problematic program.
4. Click End task.
5. Wait a few seconds and check if Windows becomes responsive again.

If the same application frequently stops responding, try updating it, reinstalling it, or checking for known compatibility issues.

Identifying and closing frozen applications is one of the quickest ways to fix a Windows 10 PC that has become unresponsive.

Fix 3: Restart Windows Explorer

If the taskbar, Start menu, desktop icons, or File Explorer stop responding, the problem may be with the Windows Explorer process rather than the entire operating system. Restarting Windows Explorer can refresh these components and restore normal functionality.

To restart Windows Explorer:

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

If Windows Explorer is not visible:

1. In Task Manager, click File > Run new task.
2. Type explorer.exe and click OK.

Once the process restarts, check whether the taskbar, Start menu, and desktop are responding normally again.

This fix is especially useful when only parts of Windows appear frozen while the rest of the system continues to function.

Fix 4: Disconnect External Devices

External hardware such as USB drives, printers, webcams, external hard drives, and docking stations can sometimes cause Windows 10 to stop responding. This usually happens when a device has a faulty driver, hardware issue, or compatibility problem.

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

To check for hardware conflicts:

1. Save your work if possible.
2. Disconnect all non-essential external devices, including:
   • USB flash drives
   • External hard drives
   • Printers
   • Webcams
   • USB hubs
   • Other accessories
3. Restart your computer.
4. Use the PC normally and monitor its behavior.

If Windows 10 starts normally, reconnect the devices one at a time until you identify the problematic hardware.

Once identified, try updating the device driver, using a different USB port, or replacing the device if the issue continues.

Fix 5: Run Windows Memory Diagnostic

Faulty or unstable RAM can cause Windows 10 to freeze, display “Not Responding” errors, crash unexpectedly, or behave unpredictably. If your computer frequently becomes unresponsive without an obvious cause, it’s a good idea to check the system memory for errors.

Windows includes a built-in tool called Windows Memory Diagnostic that can scan your RAM for problems.

To run Windows Memory Diagnostic:

1. Press Windows + R to open the Run dialog box.
2. Type mdsched.exe and press Enter.
3. Select Restart now and check for problems (recommended).
4. Your computer will restart and begin the memory test automatically.
5. Wait for the scan to complete.
6. Windows will restart again and display the test results after you sign in.

If memory errors are detected, the issue may be caused by a faulty RAM module. In that case, try reseating the memory sticks, testing one module at a time, or replacing the defective RAM.

Checking your system memory can help identify hardware-related causes of Windows 10 freezing and unresponsive behavior.

Fix 6: Check Disk Errors (CHKDSK)

If your hard drive or SSD contains file system errors, Windows may slow down, freeze unexpectedly, or display “Not Responding” messages when opening files or applications.

Running the Check Disk utility can scan your drive for errors and repair common file system problems.

To check your drive for errors:

1. Open Command Prompt as Administrator.
2. Type the following command and press Enter:chkdsk C: /f
3. If prompted, type Y and press Enter.
4. Restart your computer.
5. Windows will scan and repair disk errors during startup.

After the scan completes, check whether Windows is responding normally.

If the tool reports numerous errors, it may indicate that your storage drive is beginning to fail and should be monitored closely.

Fix 7: Repair System Files Using SFC and DISM

Corrupted Windows system files can cause applications to stop responding, trigger random freezes, and affect overall system stability. If essential operating system files are damaged by failed updates, malware, or improper shutdowns, Windows may not function properly.

Windows includes two built-in repair tools—System File Checker (SFC) and Deployment Image Servicing and Management (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 PC if Windows repairs any files.

If the issue persists, run DISM:

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

These tools can repair damaged system files and often resolve stability problems that cause Windows 10 to become unresponsive.

Fix 8: Update Device Drivers

Outdated, corrupted, or incompatible device drivers can cause Windows 10 to become unresponsive, freeze randomly, or display “Not Responding” errors. Driver issues are particularly common after Windows updates or when installing new hardware.

Updating your drivers can resolve compatibility problems and improve overall system stability.

To update device drivers:

1. Right-click the Start button and select Device Manager.
2. Expand the category of 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 any available updates.
6. Restart your computer.

For the best results, download the latest drivers directly from your PC, motherboard, or hardware manufacturer’s official website, especially for:

• Graphics drivers
• Chipset drivers
• Storage controllers
• Network adapters

If Windows started becoming unresponsive after a recent driver update, you can also roll back the driver:

1. Open Device Manager.
2. Right-click the affected device and select Properties.
3. Open the Driver tab.
4. Click Roll Back Driver if the option is available.
5. Restart your PC.

Keeping drivers updated helps ensure Windows can communicate properly with your hardware and can prevent many freezing and responsiveness issues.

Fix 9: Reset Windows 10 (Last Resort)

If Windows 10 continues to freeze or display “Not Responding” errors after trying all the previous fixes, the operating system may have deeper issues that cannot be repaired through normal troubleshooting. Resetting Windows can remove software conflicts, repair damaged system components, and restore default settings.

Before proceeding, back up important files to avoid data loss.

To reset Windows 10:

1. Press Windows + I to open Settings.
2. Go to Update & Security > Recovery.
3. Under Reset this PC, click Get started.
4. Select Keep my files to preserve personal data.
5. Follow the on-screen instructions to complete the reset process.
6. Wait for Windows to reinstall and restart.

After the reset is complete, install the latest Windows updates and device drivers, then test your computer to see if the issue has been resolved.

A reset should only be used when other troubleshooting methods fail, but it is often effective for fixing persistent freezing, crashing, and unresponsive system problems.
