Part 1: How to Fix PC Turns on but No Display or Power to Keyboard?

As we said earlier, there are lots of methods to fix "PC turns on but no display keyboard or mouse." Let's discuss them in detail so that you can easily follow and fix your computer by yourself.

Remember, each method is designed to help you troubleshoot and fix the "PC turns on but no display or power to keyboard" issue. If one method doesn't work, move on to the next.

Method 1. Force Restart Your PC

Sometimes, your computer may encounter a temporary glitch or hang during startup, preventing the display from working and the keyboard from responding. Performing a force restart helps in clearing any potential hiccups during the booting process.

By forcing a restart, you are effectively giving your computer a fresh start and a chance to boot up properly.

To force restart your PC, follow these simple steps:

• Press and hold the power button on your computer for about 10 seconds until it shuts down completely.
• Wait for a few seconds and then press the power button again to turn it back on.

Method 2. Test the Monitor

If you are still facing a "PC turns on but no keyboard or display" problem, the issue might not be with your computer itself, but rather the monitor. So, it's essential to test the monitor's functionality to rule out any hardware problems.

Loose connections, damaged cables, or a malfunctioning monitor can all cause a blank screen even when your PC is turning on correctly.

Here's how to test it:

• Ensure the monitor's power cable is securely plugged into an electrical outlet and the monitor itself.
• Check the video cable connecting the monitor to your PC. Ensure it's tightly connected at both ends.
• If you have another monitor or a TV with an HDMI port, try connecting your PC to it. This will help you determine if the issue is with the monitor or the PC.

Method 3. Reconnect Your Monitor to PC

Loose connections can also cause a loss of signal between your computer and the monitor, resulting in a blank screen. By unplugging and securely reconnecting the video cable between your PC and the monitor, you can ensure that the signal is being transmitted properly.

Follow these steps to ensure everything is connected correctly:

• Turn off your computer and unplug the power cable.
• Disconnect the video cable from both the monitor and the PC.
• Reconnect the video cable securely to both ends.
• Plug the power cable back in and turn on your computer to check if the display works.

Method 4. Disconnect Your Peripherals

Sometimes, external devices connected to your PC can interfere with the booting process, leading to display and keyboard issues. Disconnecting all unnecessary peripherals can help you identify if any of these devices are causing the problem.

Here is how you can do that.

• Turn off your computer completely and unplug any external devices connected to your PC, such as external hard drives, printers, and USB devices.

  
• Keep only your monitor and keyboard connected to the computer.
• Power on your computer to see if the display issue is resolved and if the keyboard starts working.
• If the problem is fixed, one of the disconnected peripherals may have been causing the interference. Reconnect them one by one to identify the problematic device.

Method 5. Reset BIOS Settings to Default

Incorrect BIOS settings can lead to compatibility issues or misconfigurations that result in "PC turns on but no display or keyboard lights." By resetting the BIOS settings to their default values, you eliminate any potential problematic configurations and restore the BIOS to a known, stable state.

Here's how to reset them to default:

• Restart your computer and repeatedly press the BIOS access key usually F2 or F12 during startup to enter the BIOS settings.

• Now you will have to look for the "Load Optimized Defaults" or "Load Setup Defaults" option and select it.

  
• Save the changes and exit the BIOS. Your PC will restart, and the BIOS settings will be reset to default.

Method 6. Reinstall Your RAM

Faulty or improperly seated RAM modules can cause display problems. Loose or faulty RAM can disrupt the system's ability to access critical data, leading to display and keyboard failures.

To reset your RAM, follow these steps:

• Turn off your computer and unplug the power cable.
• Open your computer's case to access the RAM slots.

• Remove the RAM modules carefully by pressing the side clips and gently pulling them out.

  
• Now wait for a few minutes and then reinsert the RAM modules firmly into their slots until the side clips click into place.
• Close the case, plug the power cable back in, and turn on your computer.

Method 7. Change the CMOS Battery

The CMOS battery on your computer's motherboard is responsible for keeping the BIOS settings and system time when the computer is powered off. If the battery is old or depleted, it can lead to BIOS configuration errors, including display problems. Changing the CMOS battery with a fresh one can resolve these issues and restore the correct BIOS settings.

Here's how to replace it:

• Turn off your computer, unplug the power cable, and open the case.
• Locate the CMOS battery on the motherboard. It looks like a small silver coin.

• Carefully remove the old battery from its slot.

  
• Insert the new CMOS battery, ensuring it is properly oriented.
