15 Ways to Fix Computer Turns on But No Display in 2023


In today’s digital age, our computers have become an integral part of our daily lives. Whether it’s for work, entertainment, or communication, a functional computer is essential. However, one of the most frustrating issues computer users face is when their computer turns on, but the screen remains blank. In this article, we’ll explore 15 effective ways to troubleshoot and fix the “Computer Turns on But No Display” issue in 2023.

1. Check Your Display Connection

The first step in resolving a “no display” issue is to ensure all display cables are properly connected. Sometimes, a loose or disconnected cable can be the root cause of the problem. Double-check the connections between your computer and the monitor.

2. Verify Monitor Power

Before diving deeper into troubleshooting your computer, make sure your monitor is receiving power. Check if the monitor’s power cable is securely connected and if it is turned on. Some monitors have power indicators that should be lit.

3. Inspect the Graphics Card

If your computer has a dedicated graphics card, it might be the culprit. Remove the graphics card and reseat it in its slot. Dust and loose connections can lead to display issues. Ensure that the card is firmly in place.

4. Integrated Graphics Testing

In case your computer uses integrated graphics, try connecting your monitor directly to the motherboard’s video output. This can help determine if the issue lies with the graphics card.

5. Check for Display Input Source

Modern monitors often support multiple input sources, such as HDMI, DisplayPort, and VGA. Ensure that your monitor is set to the correct input source corresponding to your computer’s output.

6. Test with Another Monitor

To rule out a monitor-specific problem, connect your computer to a different monitor. If the second monitor works, the issue may be with your original monitor.

7. Resolving BIOS/UEFI Issues

Access your computer’s BIOS or UEFI settings. Sometimes, changes in these settings can lead to display problems. Ensure the settings are configured correctly, especially when it comes to the primary display.

8. RAM Reinstallation

Reseating your computer’s RAM modules can help resolve display issues caused by memory-related problems. Carefully remove and reinsert your RAM sticks one at a time, ensuring they are properly seated in their slots.

9. Power Supply Examination

Inspect your power supply unit (PSU). A malfunctioning or insufficient power supply can lead to a no display problem. Check for loose cables, and consider testing your computer with a different PSU if available.

10. Clearing CMOS

Resetting the CMOS (Complementary Metal-Oxide-Semiconductor) can resolve certain hardware configuration issues. Refer to your motherboard’s manual for instructions on how to clear the CMOS.

11. Check for Overheating

Overheating components can lead to display issues. Ensure that your computer’s CPU and GPU are adequately cooled. Clean dust from cooling components and replace thermal paste if necessary.

12. Disconnect External Devices

Disconnect all unnecessary external devices, such as USB drives, printers, and additional monitors. Sometimes, conflicts with external hardware can cause display problems.

13. Software and Driver Updates

Outdated or corrupted drivers can affect display functionality. Ensure that your operating system and graphics drivers are up to date. Visit the official website of your GPU manufacturer to download the latest drivers.

14. Hardware Diagnostics

Run hardware diagnostics to identify any potential issues with your computer’s components. Many computer manufacturers provide built-in diagnostic tools that can help pinpoint hardware problems.

15. Seek Professional Help

If you’ve exhausted all the above options and your computer still exhibits a no display issue, it’s time to seek professional assistance. A certified technician can perform in-depth diagnostics and repairs if needed.


Q1: Why is my computer turning on but not displaying anything?
