Fix VIDEO_SCHEDULER_INTERNAL_ERROR BSOD in Windows 10/11: Drivers, GPU Checks, and Repairs

VIDEO_SCHEDULER_INTERNAL_ERROR is stop code 0x00000119: Windows detected a fatal violation in the graphics scheduling path. Start by removing any GPU overclock or undervolt, install the correct graphics driver from your PC or GPU manufacturer, then check Windows system files, memory, and the GPU’s power/temperature condition. This guide applies to Windows 11 and Windows 10; note that Windows 10 reached end of support on October 14, 2025, so it no longer receives normal free security updates.

Prerequisites and compatibility​

• Sign in with an administrator account.
• Save work and back up important files before changing drivers or firmware.
• If this is a laptop or prebuilt desktop, prefer the graphics driver supplied by the PC manufacturer first. It may include switching-graphics, power, display, or dock-specific changes.
• For a desktop with a separately purchased NVIDIA, AMD, or Intel GPU, use the driver for the exact GPU model from that GPU vendor if the system maker does not provide a newer compatible package.
• Do not update BIOS/UEFI, change registry graphics timeout values, or use third-party “driver updater” utilities as a first-line fix.

Warning: Reverting overclocks, undervolts, XMP/EXPO memory profiles, or custom fan/power settings can reduce performance temporarily. It is necessary for a valid stability test. Record your current settings first so you can restore them only after the PC is stable.

Primary procedure​

1. Record the crash pattern and remove recent graphics changes​

1. Note whether the crash occurs:
   • only while gaming, video editing, streaming, or using a browser with hardware acceleration;
   • immediately after sleep, docking, connecting a second monitor, or updating a driver;
   • during ordinary desktop use or startup.
2. Disconnect nonessential display hardware for testing:
   • USB display adapters;
   • docks;
   • capture devices;
   • VR headsets;
   • external GPUs;
   • extra monitors.
   Leave one monitor directly connected to the GPU, then restart. If the BSOD stops, reconnect one device at a time after completing the driver repair.
3. Return the GPU to stock settings:
   • Open the software used for GPU tuning or monitoring.
   • Select Reset, Default, or the equivalent option.
   • Disable custom GPU core clock, memory clock, voltage, power-limit, and fan-profile changes.
   • If you enabled CPU or RAM overclocking recently, restore default firmware settings or disable the memory profile temporarily.
4. Restart Windows.

Expected result: Windows starts normally and the system is running without custom performance tuning. This does not prove the cause, but removes common stability variables before driver work.

2. Create a restore point before changing the driver​

1. Press Windows key + R.
2. Type:
   SystemPropertiesProtection
3. Select OK.
4. On the System Protection tab, select the system drive, normally Local Disk (C.
5. Confirm that Protection is On. If it is Off, select Configure, choose Turn on system protection, allocate available disk space, then select Apply.
6. Select Create.
7. Enter a descriptive name such as:
   Before GPU driver repair
8. Select Create, wait for the confirmation, then select Close.

Expected result: Windows confirms that the restore point was created successfully.

3. Install Windows updates, including offered driver updates​

Microsoft identifies hardware devices, drivers, and software as common sources of recurring stop-code errors. Install pending Windows updates before installing a vendor GPU driver.
Windows 11

1. Open Start > Settings > Windows Update.
2. Select Check for updates.
3. Install available updates.
4. Select Advanced options > Optional updates.
5. Open Driver updates. If an update is specifically offered for the display adapter, chipset, or system manufacturer, select it and choose Download & install.
6. Restart when prompted.

Windows 10

1. Open Start > Settings > Update & Security > Windows Update.
2. Select Check for updates.
3. Install available updates.
4. Select View optional updates if it appears.
5. Expand Driver updates, select relevant display or chipset updates, and choose Download and install.
6. Restart when prompted.

Expected result: Windows Update reports that the device is up to date, or no relevant optional driver updates remain.

4. Check the display adapter in Device Manager​

1. Right-click Start and select Device Manager.
2. Expand Display adapters.
3. Look for:
   • a yellow exclamation mark;
   • an Unknown device;
   • duplicate or unexpected display adapters;
   • a disabled adapter icon.
4. Right-click the active GPU and select Properties.
5. On the General tab, check Device status.
6. On the Driver tab, record the Driver Provider, Driver Date, and Driver Version.

If Device status reports a problem or the driver was installed shortly before the crashes, continue to the clean driver reinstall in the next step.

Warning: Do not disable the only active display adapter unless you know how to recover through Safe Mode. The display may go blank temporarily during an uninstall, and the screen can flicker during installation.

5. Cleanly reinstall the graphics driver​

Use this procedure when the BSOD began after a graphics-driver update, Device Manager reports a GPU issue, or simply updating the driver did not help.

1. Download the correct graphics driver installer before uninstalling anything:
   • Laptop/prebuilt PC: use the support page for the exact PC model.
   • Custom desktop: use the GPU vendor’s driver package for the exact card.
   • If the PC uses both integrated and dedicated graphics, download both the system-maker integrated graphics driver and the dedicated GPU driver.
2. Disconnect from the internet temporarily. This reduces the chance that Windows Update installs a different display driver during the cleanup.
3. In Device Manager, expand Display adapters.
4. Right-click the GPU that is crashing and select Uninstall device.
5. In the confirmation window:
   • select Attempt to remove the driver for this device or Delete the driver software for this device if the option is shown;
   • select Uninstall.
6. Restart the PC immediately.
7. After Windows starts, run the driver installer downloaded in step 1.
   • If the installer offers Clean installation, Factory reset, or Perform a clean install, use that option.
   • Install the driver and restart when prompted.
8. Reconnect to the internet after the restart.

Expected result: Device Manager lists the GPU normally under Display adapters, with no warning icon. The desktop may use a low resolution briefly before the new driver is installed; that is expected.

6. Repair the Windows component store and protected system files​

Corrupted Windows files can complicate driver installation and graphics operations.

1. Right-click Start.
2. Select Terminal (Admin) on Windows 11, or Windows PowerShell (Admin) / Command Prompt (Admin) on Windows 10.
3. Run the following command and wait for it to finish:
   DISM /Online /Cleanup-Image /RestoreHealth
4. When DISM completes successfully, run:
   sfc /scannow
5. Restart the PC.

Expected results:

• DISM should report that the restore operation completed successfully.
• SFC should ideally report: “Windows Resource Protection did not find any integrity violations.”
• If SFC says it found and repaired files, restart and run sfc /scannow once more.

7. Test memory and basic hardware stability​

The 0x119 stop code can reflect a graphics-driver fault, but Microsoft’s bug-check documentation also identifies some internal scheduler states as potentially related to memory corruption or failing hardware. Test memory before assuming the GPU is defective.

1. Press Windows key + R.
2. Type:
   mdsched.exe
3. Select OK.
4. Select Restart now and check for problems.
5. Let the memory test complete. Windows restarts automatically.

To view the result:

1. Right-click Start > Event Viewer.
2. Open Windows Logs > System.
3. Select Find in the right pane.
4. Search for:
   MemoryDiagnostics-Results
5. Review the newest result.

Expected result: The event reports that Windows Memory Diagnostic detected no memory errors.
If it reports errors, stop GPU stress testing. Restore default memory settings, reseat memory modules if you are comfortable servicing the PC, and run the PC manufacturer’s hardware diagnostics. Persistent memory errors require hardware troubleshooting.

8. Check GPU cooling, cabling, and power delivery​

Power off the PC fully before inspecting internal hardware.

Warning: Shut down Windows, switch off the PSU if it has a switch, and disconnect power before opening a desktop. Do not open a laptop chassis unless its service documentation permits it. Physical service can affect warranty coverage and can damage components if performed incorrectly.

Click to expand...

For a desktop with a dedicated GPU:

1. Confirm the graphics card is fully seated in its PCIe slot.
2. Confirm every required PCIe power connector is inserted fully.
3. If the card uses more than one power connector, use separate PSU cables where the power-supply manufacturer recommends it; avoid loose adapters or damaged extension cables.
4. Remove obvious dust buildup from GPU fans and case airflow paths using appropriate nonconductive cleaning methods.
5. Confirm GPU fans spin during a graphics load.
6. Check that the PSU is adequate for the GPU and other installed hardware.

For a laptop:

1. Use the original or correctly rated AC adapter.
2. Test while connected to AC power.
3. Ensure air intakes and exhaust vents are not blocked.
4. Update the laptop maker’s chipset, power-management, BIOS/UEFI, and graphics packages only if they are explicitly offered for the exact model.

Verification of success​

1. Restart the PC twice after all repairs.
2. Open Device Manager > Display adapters > your GPU > Properties and confirm This device is working properly appears under Device status.
3. Use the workload that previously caused the crash for at least 15 to 30 minutes:
   • the same game;
   • video-rendering task;
   • browser/video playback;
   • external-monitor or dock setup.
4. Open Reliability Monitor:
   • Press Windows key + R.
   • Type:
     perfmon /rel
   • Select OK.
   • Confirm no new Windows stopped working or hardware error entry appears after the repair and test.

A successful repair means the original workload completes without a black screen, driver reset, freeze, or another VIDEO_SCHEDULER_INTERNAL_ERROR stop code.

Alternate method: Roll back a newly installed GPU driver​

Use this only if crashes began immediately after a specific graphics-driver update and the prior driver was stable.

1. Right-click Start > Device Manager.
2. Expand Display adapters.
3. Right-click the GPU > Properties > Driver tab.
4. Select Roll Back Driver.
5. Choose the reason that best matches the issue, then select Yes.
6. Restart Windows.

If Roll Back Driver is unavailable, Windows does not retain a previous driver package. Use the clean reinstall procedure instead and install the last known stable driver from the PC or GPU manufacturer.

Troubleshooting and rollback/escalation​

The PC crashes before you can uninstall the driver​

Start in Safe Mode:

• Windows 11: Start > Settings > System > Recovery > Advanced startup > Restart now.
• Windows 10: Start > Settings > Update & Security > Recovery > Advanced startup > Restart now.

Then select Troubleshoot > Advanced options > Startup Settings > Restart, then press 4 or F4 for Safe Mode. Safe Mode starts Windows with a limited set of drivers and services. Perform the graphics-driver uninstall there, then restart normally and install the correct driver.
If BitLocker device encryption is enabled, have the BitLocker recovery key available before entering Windows Recovery Environment.

The screen stays black after driver removal or installation​

Wait several minutes once; display-driver changes can reset the screen. If there is still no picture:

1. Press Windows key + Ctrl + Shift + B to request a graphics-driver reset.
2. Check the monitor input source and cable.
3. Move the cable to another output on the GPU.
4. If the processor has integrated graphics and the motherboard supports video output, connect the monitor to the motherboard output temporarily.
5. Enter Safe Mode and reinstall the system-maker or GPU-vendor driver.

The BSOD occurs only with a browser, video call, or streaming application​

Update the affected app and test with its hardware acceleration disabled. For example, in most Chromium-based apps, open Settings, search for hardware acceleration, turn off Use hardware acceleration when available, then restart the app. If the crash stops, retain the updated GPU driver and leave acceleration off until a later driver release proves stable.

The BSOD persists after a clean driver reinstall​

Treat this as a possible hardware or platform issue when any of the following is true:

• Windows Memory Diagnostic reports errors.
• The PC crashes under stock settings in multiple graphics workloads.
• You see visual artifacts, colored blocks, random lines, or corruption before Windows crashes.
• The GPU disappears from Device Manager, reports a device error, or fails in another known-good PC.
• The error began after installing a new GPU, PSU, riser cable, dock, monitor, or RAM.
• The crash continues even in Safe Mode or during Windows setup.

At that point, leave the system at stock settings, remove recently added hardware, run the manufacturer’s hardware diagnostics, and arrange repair or warranty service for the GPU, power supply, motherboard, or laptop.
