The most likely cause is a GPU driver stall, where the display pipeline locks up while the mouse driver keeps running independently. Press Win + Ctrl + Shift + B first to reset the graphics driver without losing your work. If that does not unlock the screen, work through the driver and RAM fixes below. Most cases resolve without reinstalling Windows.
Introduction
Your screen is completely locked, but you can still move the cursor. Nothing clicks, Ctrl+Alt+Del does nothing, and the only way out seems to be holding the power button. This is one of the most frustrating Windows 11 failures because the system feels alive yet completely unreachable.
This guide explains exactly why the screen freezes while the mouse stays active, identifies the top causes, and walks you through fixes ordered from fastest to most involved.
Symptoms
- Screen locks mid-use; cursor moves freely but clicks register nothing
- Ctrl+Alt+Delete is unresponsive
- Audio keeps playing through a frozen image
- Discord, voice chat, or background apps continue running normally
- The freeze resolves only after a hard power-off and reboot
- Taskbar, Start menu, and open windows are all unresponsive
- Freeze happens randomly, during gaming, idle, or after alt-tabbing
- Screen freezes immediately after waking from sleep
What Causes Windows 11 Screen Frozen But Mouse Moves
The mouse and screen use separate driver stacks. The mouse runs through HID (Human Interface Device) drivers that rarely stall. The display runs through the GPU driver pipeline. When the GPU stalls, the screen locks but the HID stack keeps sending cursor position updates, which is why the cursor still moves on a frozen image.
1. GPU Driver Fault The GPU driver pipeline hangs mid-render, locking the display while the rest of the system lags behind. This happens after Windows Update installs an incompatible driver version, after a failed driver update, or when Hardware Accelerated GPU Scheduling (HAGS) causes conflicts. Confirmation sign: The freeze happens during GPU-heavy tasks like gaming, video playback, or switching between apps.
2. Corrupted or Unstable RAM A failing RAM module causes silent freezes that look exactly like GPU stalls. The CPU writes to a bad memory address, the operation stalls, and the shell becomes unresponsive. RAM issues often cause freezes during idle or light tasks with no obvious trigger. Confirmation sign: Freeze happens randomly with no consistent pattern, even during low-activity tasks like browsing.
3. Corrupted Windows System Files or Fast Startup Damaged system files cause the display compositor (DWM.exe) to stall mid-render. Fast Startup saves the kernel session on shutdown and restores it on boot. If that saved state is corrupted after a driver update or Windows patch, every session starts from a broken baseline. Confirmation sign: Freezes began after a Windows update or started happening immediately after boot from a normal shutdown.
How to Fix Windows 11 Screen Frozen But Mouse Moves
Fix 1: Reset the Graphics Driver
Cost: Free
Time: 30 seconds
Difficulty: Easy
- During the freeze, press Win + Ctrl + Shift + B simultaneously.
- The screen will go black for 1-2 seconds, then return.
- If the desktop becomes responsive, you are done for now.
- If the screen stays frozen, proceed to Fix 2.
Expected Result: Display driver resets and screen unlocks without losing open work.
If Failed: The freeze is deeper than a driver timeout. Move to Fix 2.
Fix 2: Disable Hardware Accelerated GPU Scheduling (HAGS)
Cost: Free
Time: 5 minutes
Difficulty: Easy
- Press Win + I to open Settings.
- Go to System > Display > Graphics.
- Click Default graphics settings.
- Toggle Hardware-accelerated GPU scheduling to Off.
- Restart the laptop.
Expected Result: Display pipeline conflicts caused by HAGS stop, ending the freeze cycle.
If Failed: HAGS was not the trigger. Move to Fix 3.
Fix 3: Update or Roll Back the GPU Driver
Cost: Free
Time: 10-20 minutes
Difficulty: Easy
- Right-click the Start button and open Device Manager.
- Expand Display adapters and right-click your GPU.
- Select Update driver > Search automatically for drivers.
- If Windows finds a newer driver, install it and restart.
- If the freeze started after a recent driver update, choose Properties > Driver > Roll Back Driver instead.
- For NVIDIA laptops, download the driver directly from nvidia.com. For AMD laptops, use amd.com. For Intel integrated graphics, use the Intel Driver and Support Assistant.
Expected Result: The GPU driver stabilizes and the freeze stops.
If Failed: Driver is not the root cause. Move to Fix 4.
Fix 4: Disable Fast Startup
Cost: Free
Time: 3 minutes
Difficulty: Easy
- Open Control Panel (search from Start).
- Go to Hardware and Sound > Power Options.
- Click Choose what the power buttons do on the left panel.
- Click Change settings that are currently unavailable.
- Uncheck Turn on fast startup.
- Click Save changes and do a full restart.
Expected Result: Windows performs a full cold boot each time instead of restoring a potentially broken saved state.
If Failed: Fast Startup was not preserving a corrupted session. Move to Fix 5.
Fix 5: Run DISM and SFC to Repair System Files
Cost: Free
Time: 15-30 minutes
Difficulty: Easy
- Search cmd in Start, right-click Command Prompt, and select Run as administrator.
- Type the following and press Enter:
DISM /Online /Cleanup-Image /RestoreHealth
- Wait for DISM to finish. It needs an active internet connection to download repair files.
- Once complete, type:
sfc /scannow
- Wait for SFC to finish scanning and repairing.
- Restart the laptop.
Expected Result: Corrupted system files causing DWM.exe stalls are repaired.
If Failed: System files were not the cause. Move to Fix 6.
Fix 6: Run Windows Memory Diagnostic
Cost: Free
Time: 15-30 minutes
Difficulty: Easy
- Press Win + R, type mdsched.exe, and press Enter.
- Select Restart now and check for problems.
- The laptop will reboot into the diagnostic tool automatically.
- Let the scan complete. Results display after Windows restarts.
- If errors are found, open Event Viewer > Windows Logs > System and search for MemoryDiagnostics-Results to see the full report.
Expected Result: RAM faults causing random freezes are identified.
If Failed: RAM passed the basic test. Reseat the RAM module (Fix 7) or run MemTest86 for a deeper check.
Fix 7: Reseat the RAM Module
Cost: Free
Time: 15 minutes
Difficulty: Moderate (requires opening the laptop bottom panel)
- Power off the laptop completely and unplug the charger.
- Remove the bottom panel using a Phillips-head screwdriver.
- Locate the RAM module (a small rectangular stick in a socket).
- Press the side clips outward to release the module, then pull it out at an angle.
- Inspect the gold contacts. If there is oxidation, gently clean with a pencil eraser.
- Reinsert the module at a 45-degree angle until it clicks flat.
- Reassemble and restart.
Expected Result: Poor RAM contact causing intermittent stalls is corrected.
If Failed: Move to Fix 8.
Fix 8: Check for Overheating
Cost: Free (software) / $5-20 for thermal paste
Time: 10 minutes to diagnose; 30-60 minutes to re-paste
Difficulty: Moderate
- Download HWMonitor (free) and run it.
- Watch GPU and CPU temperatures during normal use.
- A laptop GPU above 90 degrees Celsius under load is running hot. Above 95 is critical.
- Clean the laptop vents with compressed air through the exhaust port.
- If temperatures remain high after cleaning, the thermal paste on the GPU die may need replacement.
Expected Result: Thermal throttling that causes display stalls is eliminated.
If Failed: Overheating is not the cause. Consider a Windows reset or seek professional diagnosis.
Mistakes to Avoid
Reinstalling Windows as a first step. Most freeze causes are fixable through driver updates, HAGS settings, or RAM reseating. A Windows reinstall takes hours and solves nothing if a faulty RAM module is the root cause.
Trusting Windows Update for GPU drivers. Windows Update delivers generic driver packages that often lag behind the version your specific GPU model needs. Always download GPU drivers directly from NVIDIA, AMD, or Intel’s official site.
Skipping DISM before running SFC. SFC repairs system files but pulls from the local Windows image. If that image is also corrupted, SFC repairs nothing. Run DISM first so SFC has a clean image to reference.
Forcing power-off repeatedly without diagnosing. Constant hard resets without fixing the underlying cause risk corrupting the SSD and losing file system integrity over time.
When to Stop and Get Professional Help
Stop attempting DIY repairs if the freeze is accompanied by burn smells, the laptop case feels extremely hot to the touch, or the screen shows visual artifacts like colored blocks before freezing. These signs point to failing GPU hardware or a damaged power delivery circuit. If Windows Memory Diagnostic and MemTest86 both report errors across multiple RAM slots, the motherboard RAM controller may be failing. Take the laptop to a repair shop for hardware-level testing before spending money on replacement parts.
Prevention Tips
- Set GPU drivers to update manually, not automatically through Windows Update.
- Keep the laptop’s exhaust vents clear — do not use it on soft surfaces like beds or cushions.
- Run DISM and SFC after every major Windows 11 feature update.
- Keep at least 15% of your SSD free to prevent write stalls that trigger system freezes.
- Disable Fast Startup permanently to prevent corrupted session states from persisting across reboots.
Frequently Asked Questions
Why does the mouse move if the screen is completely frozen? The mouse runs through the HID driver stack, which operates independently from the GPU rendering pipeline. When the GPU stalls and locks the display, the mouse driver keeps sending position data, so the cursor keeps moving even though nothing else responds.
Will pressing Win + Ctrl + Shift + B lose my open work? No. This shortcut resets the display driver only. Open applications, documents, and browser tabs remain intact. It is the safest first step to try before a hard power-off.
Can a Windows 11 update cause the screen to freeze like this? Yes. Feature updates can replace a stable GPU driver with an incompatible version, or break the Fast Startup saved session. Disabling Fast Startup and rolling back the GPU driver after a problematic update resolves most post-update freeze cases.
How do I know if my RAM is causing the freeze? Run Windows Memory Diagnostic first. If it reports no errors but freezes continue, run MemTest86 from a USB drive for a deeper scan. RAM-related freezes tend to be random, happen during light tasks, and occur with no consistent trigger.
Conclusion
Windows 11 screen freezing with a working mouse almost always points to a GPU driver stall, unstable RAM, or corrupted system files. Start with Win + Ctrl + Shift + B to reset the display driver instantly, then work through the driver and system repair steps above. If software fixes do not stop the freezes, reseating the RAM or checking for overheating will usually resolve the hardware-level cause.
