Fix 4: Disconnect Peripherals

Occasionally, peripherals like a mouse, printer, or scanner could be the culprit. To determine if they're causing the "computer starts but no display" issue, follow these steps: 1. Disconnect all peripheral devices from your computer, including USB devices, external hard drives, and any other connected hardware. 2. Power off your computer completely. 3. Wait for a few moments to ensure any potential electrical charges have dissipated. 4. Plug in only the essential components, such as the keyboard and monitor (if not built-in). 5.

1. Press and hold the power button until your computer turns off.
2. Unplug all external devices (such as your printer, scanner, mouse, etc.).

A faulty connection between your motherboard and RAM can also cause this issue. Thankfully, you can rectify it by reseating your RAM. Here are the detailed steps to follow:

Step 1. Press and hold the power button until your computer turns off.

Solution 6: Reset BIOS Settings to Default

Your computer might start up with a black screen due to incorrect BIOS settings. To check if this is the root cause, you can reset your BIOS to its default settings. Follow these steps to do so: 1. **Restart your computer**: First, turn off your computer and then turn it back on. As it boots up, pay attention to any manufacturer-specific messages that indicate how to enter BIOS. 2. **Enter BIOS**: Typically, you can access BIOS by pressing a specific key like F2, F10, Delete, or Esc during the initial startup screen. The key varies depending on the computer manufacturer, so refer to the on-screen instructions or your user manual for the correct key. 3. **Find the Reset Option**: Once in BIOS, navigate through the menus using the arrow keys on your keyboard. Look for an option labeled "Load Default Settings," "Load Optimal Defaults," "Factory Defaults," or something similar. This will reset the BIOS to its original configuration. 4. **Confirm the Reset**: After selecting the reset option, a prompt will likely appear asking you to confirm your choice. Press 'Enter' to proceed with the reset. 5. **Save and Exit**: After confirming the reset, save the changes by selecting "Save and Exit" or a similar option. This will exit BIOS and reboot your computer with the new settings. 6. **Check for Improvement**: Your computer should now restart with the default BIOS settings. If the black screen issue persists, there may be other underlying problems that require further troubleshooting. Remember, if you're unsure about any steps or feel uncomfortable making changes, consult your computer's user manual or seek assistance from a professional.
