Causes of Computer Turns On But No Display

The most common reasons for a computer failing to display anything upon booting are faulty cables and loose connections. Cable damage can be difficult to measure externally, as they may appear fine but fail to function properly. Other causes include:

  • Incorrect display configurations
  • GPU or RAM issues
  • Problematic peripheral devices
  • BIOS configuration issues
  • You hit the power button, but your monitors remain blank, and your peripherals show no signs of life. This scenario is not uncommon, and it often leaves users perplexed.

    However, with the right troubleshooting steps, you can resolve this issue efficiently.

    How to Fix Computer Turns On But No Display Issue?

    If your computer is turned on but not displaying anything on the screen, it could be due to various hardware issues such as damaged cables or loose connections. Resolving these issues, like using different cables or reseating components, is often straightforward. However, computer turns on but no display could stem from other causes as well.

    Let's discuss them in detail.

    Method 1: Check Your Monitor

    Start by verifying if your monitor is functioning properly, as monitor issues can result in a black screen. Connect it to another computer or test it individually to ensure it's working.

    One method is to pair it with a spare computer chassis and check if the issue disappears. If you don't have access to another PC, simply detach the monitor from the system and power it on separately.

    If it shows no defects, your monitor should flash lights, brighten up, or greet you through on-screen prompts.

    If any type of signal from the monitor indicates it's functioning properly, but the computer continues to display a black screen, in this scenario, you must proceed with the next check; otherwise, you'll need to send the monitor for repair.

    Method 2: Ensure Your Computer is Fully Booted

    Ensure your computer is fully powered on. Sometimes, it might seem like your computer is not booting, but it's actually in a standby/sleep mode, causing no display on the monitor or keyboard.

    Method 3: Reinstall RAM

    Poor connection between the RAM and motherboard can also cause a computer to fail to boot with power. In such cases, reseating the RAM can resolve the issue. Here are the steps:

    reinstall ram

    Step 1. Press and hold the power button until your computer shuts down.

    Step 2. Disconnect the AC power cord from the power source and then open the computer chassis. (This process will vary depending on the type of computer you have. If you are unsure how to proceed, refer to your computer documentation or seek professional assistance.)

    Step 3. On your motherboard, remove your RAM from the memory slots.

    Step 4. Reinsert the RAM into the slots..

    Step 5. Reconnect the AC power cord to the power source and then turn on the computer.

    If your computer still fails to resolve the issue of the computer operating with a black screen, do not worry. Proceed to check the following repairs.

    Fix 4: Reset BIOS to Fix Screen Blackout

    Access the BIOS settings utility immediately after your PC boots up to reset it. This can often rectify hardware configuration errors causing the black screen issue.

    As long as your monitor is receiving power, you can access the BIOS settings utility and reset it.

    To reset BIOS through the BIOS settings utility:

    Step 1. Turn on your computer and press the F2/F8/F10/F11/F12/Del key (varies among different computers) to access the BIOS settings. Check your motherboard brand and search online or refer to the manual to find the exact key, as it varies depending on the chipset manufacturer.

    Step 2. Look for options such as "Restore Defaults," "Reset," "Load Optimized Defaults," or similar.

    reset bios

    Step 3. Select the option and then follow the on-screen prompts to confirm.

    Step 4. Choose any option similar to "Save and Exit." Check if the issue of booting up with a black screen or a black screen on the monitor is resolved.

    Physical reset switch:

    This scenario is rare, but some newer motherboards feature a physical switch or button on the motherboard or CPU chassis for resetting the CMOS battery/BIOS settings. If your PC has this feature, simply press the button for about 10 seconds to resolve the issue of booting up with a black screen and inability to access the system.

    Method 5: Check Display and Resolution Settings

    Inspect your display settings using the controls on your monitor. Ensure brightness levels are adequate and that the resolution isn't set higher than what your monitor supports.

    Step 1. Check the brightness level and ensure it is not completely lowered or something similar.

    Step 2. Ensure that your resolution settings are not higher than the actual resolution supported by the monitor.

    Step 3. If these steps don't help, use the "reset" option to reset all settings to default values.

    Refer to your monitor manual or visit the manufacturer's support website for further assistance.

    Method 6: Disconnect Peripheral Devices

    Faulty peripherals like speakers, webcams, or external storage drives can sometimes prevent a computer from booting properly. Try starting your PC with only essential devices connected.

    disconnect peripheral devices

    Step 1. Disconnect all unnecessary peripheral devices and start your PC. If this helps, one of the devices may be causing the computer screen black screen issue.

    Step 2. Insert devices one by one and restart after each insertion to identify the faulty device.

    Step 3. Once found, replace it with a new one, and the issue of the computer booting up with no display will be resolved.

    Method 7: Verify Power Supply Unit (PSU) and Voltage Switch

    Test your PSU's functionality using a multimeter or a power tester. Also, check the voltage selection switch, as an incorrect input voltage can prevent your PC from booting.

    Also, when using it, be sure to check the voltage selector switch. It may already be set correctly, as an incorrect input voltage would prevent your PC from starting altogether. Nevertheless, it's worth checking regardless.
