Computer Turn On But No Display: [2022]


computer turn on but no display

Computer turn on but no display, in this article we will help you to fix these main issue or problem. After turning on your computer, it might show the screen as dark. The reason is that your computer is turned on, but the screen remains blank or doesn’t display any information. That is becoming a frequent issue for Windows users. There are a couple of simple fixes you can attempt without visiting an expert or service center.


Steps To Fix the Computer Turn On But No Display Issue:

You may use any of the solutions listed below, but testing each one, in turn, is recommended.

Force Restart your Computer:

Computers running Windows are prone to problems when waking from hibernation or sleep state most of the time. It might appear as if the computer has been shut down in these situations, but it’s not.

The first and most obvious step to take is to reset your computer. But, because there’s no display to begin with, it is not possible to proceed as you could with a working display. So, you have to hold the power button and keep it in place until the computer is restarted.

Repeat the procedure two times, and you’ll be able to launch your Windows Startup Repair screen. However, if this approach does not solve your issue, you can proceed to the next step.

Check if your Monitor is Working Condition:

If a few forced restarts aren’t enough to fix the problem, it could indicate an issue with the monitor. Many monitors come with an indicator light to show that they are linked to the power source. If you see this light turning on, proceed to the next solution. If not, disconnect the monitor’s power plug from the power outlet and then reconnect it to determine if this fixes the problem.

The majority of monitors feature power buttons below the screen. Look for the power switch on your display before pressing it to switch it on. Be aware that most monitors take between a few seconds and a while to switch on when you press the power button. If you don’t have an LED indicator to indicate power, wait two seconds each time you move.

Connect again your Monitor to your Computer:

Sometimes, it’s not the power supply but rather the connectivity between the computer you are using and the monitor causing the problem. Unplug the cable that connects your computer from the monitor and reconnect it to check whether it functions. A broken connection is likely to result in this type of problem. Better yet, try using another link to your computer to check whether the issue is due to an issue with your cable.

Another check is that the display is connected to the correct connector on the laptop computer. Most computers have multiple HDMI/VGA ports. Suppose you’re not specific test every port one at a time.

If you have another computer, you can connect the monitor to it. If it is working on this machine, it’s not a problem related to your monitor but the computer itself or its video ports.

Remove your Peripherals:

Other peripherals such as printers, mouse, or scanners might be responsible in some instances. The best method to determine if the issue is one or the other is to unplug all of them and reconnect them one by one. The first step is to shut your computer off by pressing your power switch for a few minutes. After that, you can disconnect all your peripherals, except for your keyboard.

Switch your computer on once more. If your display is functioning, you can reconnect each peripheral one and restart your PC each time to check whether the issue recurs.

If you find that removing the peripherals won’t solve the issue, go on to the next step.

Reinstall your RAM:

If a computer on a desktop turns on, you can hear a sound. The beep is the first examination that computers make to check if their peripherals are operating correctly or not. The problem is most likely in the RAM if the beep doesn’t sound. Removal and reinstallation of the RAM could fix the problem in this scenario.

Of course, you’ll need to turn off the computer using the power switch for a few seconds before. To protect yourself, take the time to disconnect your computer from the power source by unplugging the cable.

Then, take off the side panel of the cabinet for your computer to expose the motherboard and those RAM slots. RAM slots generally come with two clips on both ends to secure the RAM in the right place. Take those clips off to release the RAM. Then slowly pull it back upwards. If you’ve got isopropyl alcohol in your possession, add a few drops of it on a fresh piece of cloth and then wipe the bottom of the RAM, which is plugged into the slot. Put the RAM in several minutes.

After a short time has expired and the alcohol has been completely gone, insert the RAM into the slot and put the clips back in the place. Start your computer and check if you can hear the sound. If not, you might have to test using an alternative RAM.

 Reset your BIOS Settings:

Resetting your BIOS can also help fix this problem. But, as there isn’t a display to display the menu initially, You will need to reset it through hardware. The motherboard houses the CMOS battery, which powers the BIOS. If you take it off and then reinstall it, the BIOS settings will be reset to their default settings. Make sure you shut off the power and disconnect the AC cable from your computer before doing this.

Repair Corrupt System Files:

If nothing else works, it could be in the Windows Installation. Incorrect or missing installation files are often the cause of issues with booting. A system scan is a great way to identify any problems causing them and resolve these issues. There are two methods to do this:

  1. You can use a Windows repair tool such as Restore. It can analyze your entire PC for corrupt or missing Windows systems files.
  2. If you are not keen to utilize any third-party software or software, you could opt for an inbuilt System File checker tool. However, it cannot detect problems in the registry or damaged DLL files. So, it isn’t an absolute solution.


A display is among the essential peripherals required for computer use. But, a display that isn’t working could be due to the failure of the boot process. If you own additional monitors around, it is recommended to test your computer using them to ensure there isn’t a problem regarding your screen. If all of the methods above are not working, it might be an appropriate time to present the computer off to an expert to determine the problem.
