Fix 2. Restart the Graphics Driver

If the monitor randomly goes black and comes back on, Windows includes a built-in shortcut to restart your graphics driver instantly.

Simultaneously press Win + Ctrl + Shift + B. Your monitor will flash briefly and beep as Windows reloads the display system, allowing you to resolve temporary graphics crashes without losing your work or rebooting your PC.

Fix 3. Update or Reinstall Graphics Driver

Graphics drivers connect your operating system to your graphics card. If these drivers are old or not working properly, communication can break down. This may cause random temporary black screens. Do the following steps to update the graphics driver:

1. Right-click the Start menu and select Device Manager.
2. Expand Display adapters.
3. Right-click your graphics card.
4. Select Update driver.
5. Choose Search automatically for drivers.

If updating does not help, reinstall the graphics driver with these steps:

1. Open Device Manager.
2. Right-click your graphics card.
3. Select Uninstall device.
4. Restart your computer.

Now, Windows will automatically reinstall the driver.

Fix 4. Adjust Display Settings

It is necessary to make sure the refresh rate and resolution match your monitor to avoid conflicts. Otherwise, the monitor may go black to change modes.

When your computer screen keeps going black, check the refresh rate & resolution and adjust them.

Step 1: Right-click on the desktop and choose Display settings to access the Display page in Settings.

Step 2: Under Scale and layout, go to Display resolution, and select the recommended resolution.

Step 3: In Windows 10, hit Advanced display settings and click Display adapter properties for Display 1.

Step 4: In the Monitor tab, set the refresh rate to a stable value like 60 Hertz and save the change.

Then, your monitor may not go black randomly.

Fix 5. Check Power Settings

Improperly configured power settings can be another cause if your monitor keeps going black for a second. Make sure you don’t set the computer to turn off the display after a long period of inactivity.

Step 1: In Windows 11, go to Settings > System > Power & battery, expand Screen and sleep, and set all the options to Never.

In Windows 10, navigate to Settings > System > Power & sleep. Under Screen and Sleep, choose Never.

Step 2: Type screen saver and hit Enter.

Step 3: Ensure Screen saver is set to None and save the change.

Fix 6. Disable Sync

Features like G-Sync and FreeSync synchronize a monitor’s refresh rate with a graphics card’s frame rate to prevent screen tearing & stuttering for smoother gaming.

However, an incompatibility issue between the graphics driver or monitor and the sync feature can cause the screen to turn black.

Many users recommend turning off features to resolve the issue. Now, try this way.

For AMD

Step 1: Press the Menu button on your monitor.

Step 2: Navigate to the Setup option, Reset, or a similar one.

Step 3: Hit the Reset button.

Fix 9. Disable Hardware Acceleration and Check for Overheating

Hardware acceleration or overheating can cause random black screen issues, especially during heavy workloads.

Try disabling hardware acceleration in apps like Chrome, Edge, or other graphics-related programs. Also, clean dust from fans and vents, ensure proper airflow, and check CPU/GPU temperatures to rule out overheating.

If the black screen only happens during gaming or high usage, overheating may be the cause.

Fix 10. Use System Restore or Reset Windows

If the black screen started after installing a driver, update, or application, System Restore may help. To use System Restore:

• Search for Create a restore point
• Open System Properties
• Select System Restore
• Follow the instructions

If nothing works, consider resetting Windows.

Fix 11. Check Monitor, Graphics Card, or PSU

If none of the methods above works, the monitor, power supply, or graphics card is likely to get faulty. We suggest that you take the computer to a repair shop. If you don’t have computer skills, do not check your PC components by yourself to prevent further damage.

What to Do If Screen Goes Black but Computer Is Still Running

If your PC is still running but the monitor shows a black screen:

• Press Win + Ctrl + Shift + B to restart the graphics driver
• Check monitor and cable connections
• Disconnect unnecessary peripherals
• Try another display
• Restart Windows Explorer (If you see a mouse cursor)
• Force a hard restart

This usually points to a temporary graphics driver glitch, a loose cable, or a hardware issue.
