Below are seven tried-and-true ways, but before we dive in, it’s essential to understand what triggers the “Computer Turns on but No Display” problem in the first place.
Causes Of “Computer Turns On But No Display” Issue
In most cases, the following are the most likely causes of your “PC turns on but no display” problem:
- Connecting cables that are broken or damaged.
- An issue with the Power Supply Unit.
- Peripheral equipment that needs to be fixed.
- A display that is not correctly configured.
- A GPU or RAM is causing problems.
- A BIOS that has been improperly configured.
- Incorrect monitor input.
Now that you are in this situation let’s solve it without further ado.
If you have recently attempted to use your computer, turned on the monitor, and discovered no display on the screen, worry not. The following is a list of seven (step-by-step) potential solutions to the problem “PC turns on but no display.”
Solution 1: Check all Connections
If your computer boots up but shows no output, double-check all of your connections:
Step 1: Verify that every cable, port, and adapter is securely fastened. Also, ensure the power and video wires are securely attached at both ends.
Step 2: The power indicator on your screen should now be lit. If the indicator light is on, you may need to restart your computer press (Windows + Ctrl + Shift + B command)to restart the graphics driver.
Step 3: If the monitor’s light indicator is off, check if the wires are broken. Try the cables on a different computer or connect alternative cables to your system.
Step 4: If the cords appear in good working order, you should examine the input source.
Step 5: There may be a problem with your monitor if everything seems normal.
Step 6: Try a different monitor before fixing the current one.
Solution 2: Check Monitor Input
Your monitor may have more than one input port, such as several HDMI or DisplayPort connections. Some displays may allow you to switch between inputs manually. Some screens can automatically switch back to the active port, but others can’t (or can have multiple active ports at once).
- Change the input by referring to the user guide for your monitor. Change/swap the port where your computer/ screen is plugged into the next one with the same functionality.
Try the following option if that doesn’t fix the problem.
Solution 3: Ensure That The Power Voltage Is Correctly
Incorrect voltage from the electrical supply can cause the “PC turns on but no display” problem. To check, do this:
Step 1: Check the PC’s rear power cable and wall socket.
Step 2: Check all internal computer connections as Power cables to the motherboard and graphics card supply high voltage.
Step 3: If your PC doesn’t have onboard graphics, remove all hardware and accessories except the graphics card and boot drive. If the CPU has a graphics card, remove the card.
If everything is okay, try the next move.
Solution 4: Disconnect Peripherals
A blank screen or complete lack of display is sometimes the result of a disagreement between the various peripheral devices. This category includes your keyboard, mouse, speakers, webcams, external storage drivers, cameras, scanners, and more. Do this:
Step 1: Power down your computer and remove any extra hardware.
Step 2: Try turning it back on to see if it fixes the problem.
Step 3: If the problem is solved, connect your peripherals individually to narrow down the possible causes.
Step 4: Once the faulty component is identified, a new one can be installed.
Solution 5: Reset BIOS
You can use this method to determine if the RAM is malfunctioning. When you first turn on your computer, it does a POST (Power-on self-test) to see if it can adequately identify its components before loading the BIOS. If your screen has power, go ahead and rest BIOS to resolve the problem.
Take caution when resetting the BIOS, as doing so could potentially wipe all of your data and render your PC useless:
Step 1: Press the “Power” button to start the computer, then the BIOS key(often F2/F8/F10/F11/F12/Del). The BIOS password may also be accessed through the manufacturer’s website.
Step 2: Once you’ve located it, click “Restore Defaults,” “Reset,” “Load Optimized Defaults,” or something similar.
Step 3: If prompted, select ‘Yes,’ then choose “Save, ” “Exit,” or something similar.
Solution 6: Hard Reset Your PC
After ensuring your PC is fully powered and has no display, boot into safe mode and repair Windows with Automatic Repair or System Restore. In Windows 10, follow these steps to access and activate System Restore:
Step 1: Press the “Start” button on your keyboard.
Step 2: To access the Windows System folder, you’ll need to scroll down.
Step 3: Click the ‘Control Panel icon.’
Step 4: Select the ‘Small Icons View’
Step 5: Select the ‘Recovery’
Step 6: Select the ‘Configure System Restore‘ option.
Step 7: Choose your System Drive (often “C”).
Step 8: Select the ‘Settings’
Step 9: Select ‘Turn on system protection.’
Step 10: To continue, select the ‘OK’ or ‘Apply’
Step 11: To confirm your selections, select ‘OK’ at the bottom of the System Protection window.
Solution 7: Turn On the Display
Windows and macOS include options to prevent the display of on-screen content even when the monitor is powered on. The burn-in problem persists even in modern flat-screen displays, a legacy from the days of cathode ray tubes.
If a still image is shown on a CRT or flat-screen monitor for too long, it will “burn in” or permanently imprinted on the dots or pixels.
You can repair it by clicking the mouse or touching the keys on your keyboard. In response to any action, a picture will be shown.
If the screen remains blank after pressing the power button, follow these steps:
A)Windows;
Do this:
Step 1: To access your computer’s power management features, type “Power, sleep, and battery settings” into the “Start” menu search bar. After it has appeared, click on it.
Step 2: Select “Screen and Sleep.”
Step 3: Click the drop-down choice next to “When plugged in, turn off my screen after,” and then choose “Never.”
B) macOS;
Do this:
Step 1: Select the “System Preferences” button.
Step 2: Click on the “Energy Saver” button.
Step 3: Select “Never” from the “Display sleep” drop-down menu.
With that, we hope your “PC turns on but no display” is solved; consult an expert.
