Accessing the BIOS (or UEFI firmware) is essential for configuring hardware settings, changing boot order, or troubleshooting system issues. However, some users encounter a problem where the screen goes completely black when trying to enter BIOS, making it impossible to interact with firmware settings.
This issue can occur due to graphics output problems, incorrect display connections, fast boot conflicts, outdated firmware, or hardware compatibility issues. Since BIOS operates at a low level, even small hardware or firmware mismatches can result in a blank screen.
In this guide, we’ll walk you through effective methods to fix the black screen when entering BIOS on a Windows computer.
How to Fix Black Screen When Entering BIOS on Windows Computer
Before applying the fixes below, note that BIOS may still be loading in the background even if the screen is black. The goal is to restore display output during firmware access.
1. Use Integrated Graphics Instead of Dedicated GPU
BIOS may not display properly through a dedicated graphics card.
- Shut down your PC completely.
- Disconnect the monitor from the GPU.
- Connect it to the motherboard’s display port (HDMI/VGA).
- Turn on the PC and try entering BIOS again.
This ensures compatibility with firmware display output.
2. Check Monitor Input Source
Incorrect input selection can cause a blank screen.
- Turn on your monitor.
- Use the monitor’s menu buttons.
- Select the correct input source (HDMI, DisplayPort, etc.).
Make sure it matches the connected cable.
3. Disable Fast Startup
Fast Startup can skip proper BIOS initialization.
- Open Control Panel.
- Go to Power Options > Choose what the power buttons do.
- Click Change settings that are currently unavailable.
- Uncheck Turn on fast startup.
- Save changes and restart your PC.
This allows the system to fully initialize during boot.
4. Use Advanced Startup to Enter BIOS
Windows can boot directly into BIOS without key presses.
- Press Windows + I to open Settings.
- Go to System > Recovery.
- Click Restart now under Advanced startup.
- Select Troubleshoot > Advanced options > UEFI Firmware Settings.
- Click Restart.
This bypasses manual BIOS entry issues.
5. Update BIOS/UEFI Firmware
Outdated firmware can cause display problems.
- Visit your motherboard or laptop manufacturer’s website.
- Download the latest BIOS/UEFI update.
- Follow official instructions to update firmware.
Updating firmware can fix compatibility issues.
6. Reset BIOS Settings
Incorrect BIOS settings may cause display issues.
- Turn off your PC and unplug it.
- Open the case (for desktops).
- Remove the CMOS battery for a few minutes.
- Reinsert the battery and power on the system.
This resets BIOS to default settings.
7. Try a Different Display Cable or Port
Faulty cables or ports can prevent BIOS display.
- Replace the HDMI/DisplayPort cable.
- Use a different port on your PC or monitor.
- Restart and try entering BIOS again.
This ensures proper signal transmission.
8. Disconnect External Devices
External devices may interfere with boot behavior.
- Disconnect all USB devices except keyboard and mouse.
- Remove external drives or accessories.
- Restart and enter BIOS.
This minimizes hardware conflicts.
9. Check for GPU or Hardware Issues
Hardware faults can cause black screens.
- Reseat your graphics card (for desktops).
- Ensure all cables are securely connected.
- Test with another monitor if possible.
This helps identify hardware-related problems.
Conclusion
A black screen when entering BIOS on a Windows computer is usually caused by display output issues, firmware conflicts, or hardware problems. By following the steps in this guide, you can restore BIOS visibility and regain access to firmware settings.
From switching display outputs to updating BIOS, these solutions cover both simple and advanced troubleshooting methods. Once resolved, you’ll be able to access BIOS normally and manage your system settings without issues.
