If you can hear your Windows 10/11 computer turning ON but there is no display on the screen, you should be able to fix the problem using troubleshooting steps as provided below.
Computer Turns On but No Display
In many cases, the problem of computer switching ON with black or No Display on its screen or the monitor is usually related to the problem with the display itself.
However, this problem can also occur due to stuck apps, programs or processes and other reasons.
1. Inspect Connections & Monitor
Start by checking all the cables that are connected to the display on your computer and make sure that all connections are right and there are no loose connections.
Then make sure the Monitor is switched ON and you can see the power light on the monitor.
2. Power Flush the Monitor
Shut Down the computer by pressing its Power Button and unplug the Monitor from its Power Supply Source.
Wait for 60 seconds > plug the Monitor back to its Power Supply source and restart the computer by pressing the Power button.
3. Disconnect All Connected Devices
Sometimes, the problem is due to a USB plugged device becoming incompatible with Windows operating system.
Press and Hold the Power button to shut down the computer. Once the computer is completely switched OFF, remove all the USB Connected devices from your computer (Except Keyboard and Mouse).
Start the computer by pressing the Power button and see if the display is now working. If the Display is working, it confirms that the problem is due to one of the USB connected devices.
You can identify the incompatible device by connecting USB devices one-by-one to your computer, until you find the device that causes the display to switch OFF.
Once, the device is found, see if you can update its driver. If not, you will have to stop using this device.
4. Reset BIOS to Default Settings
Switch OFF the computer by pressing and holding the Power button. Once, the computer is powered OFF, disconnect the computer from its power supply source.
Wait for 60 seconds > open the casing and remove the CMOS battery from the motherboard.
After removing the battery, wait for 60 seconds and put the CMOS battery back into the Motherboard.
Close the casing > connect the computer to its power supply source and switch ON the computer.
Note: Sensitive computer parts can suffer damage due to static shock. Hence, make sure that you do not touch any part with your bare hands (Wear gloves).
