Though it may appear difficult at first, simply work your way down the list, step by step, let’s see these methods one by one.

Solution 1: Test your monitor

LED computer Monitor

When your computer starts on but no display appears on the monitor or keyboard, the first thing you should do is examine the monitor. This will tell you whether or not your monitor is in good condition. You’ll also save time on other troubleshooting techniques.

Check the power supply first. If the power supply is working properly, check to see if any of the monitor’s cables are loose. Connect the same monitor to a different PC if all of the connections are fine but the display isn’t turning on. The display is malfunctioning if it does not turn on after being connected to another computer.

Solution 2: Reconnect your monitor to your computer

Your problem might be caused by a bad connection between your monitor and your computer. Reconnecting the two devices is most likely the fix to your problem in this scenario. Here’s how you can do it:

  • Turn off your computer by pressing and holding the power button.
  • Disconnect the video cord that links your computer to your monitor.
  • Examine your computer’s and monitor’s port connections.
VGA connectors for displays
  • Examine your video wire for any damage. Reconnect your computer to your display if the video cable is in good condition. Alternatively, if you have another video cable, try connecting the two devices with it.
  • Turn on your computer and observe whether it boots up normally.

Solution 3: Force restart your computer

If all you see after clicking the power button is a black screen, try pushing the power button for 10 seconds to force shut down your computer, then turning it back on. If you perform this three times in a row, Windows Startup Repair should start automatically.

If nothing happens after turning your computer on and off a few times, it might be a hardware issue. Continue reading to learn how to solve it.

Solution 4: Disconnect your peripherals

A black screen might also be caused by some devices attached to your computer. Disconnect all of your peripherals to determine if that’s the source of the issue. Here’s how you can do it:

  • Turn off your computer by pressing and holding the power button.
  • Disconnect all external devices (your printer, scanner, mouse, etc.).
  • Turn on your computer once more.

If your computer starts up normally, one of the peripherals you removed is the source of the problem. Each device should be reinstalled into your PC and tested each time. Then you’ll track down the precise gadget that’s causing your issue.

Solution 5: Test the VGA cable

Due to a malfunctioning VGA cable, the monitor sometimes does not display anything after receiving power. If the first approach found your display to be fine, try changing the VGA cable. Also, check to see whether the VGA cable’s connection is broken. If your monitor is still blank after replacing the VGA cable, proceed to the next step in the troubleshooting process.

Solution 6: Identify the beep codes

A beeping sound is produced by the computer’s built-in speaker. You may have heard this beep sound when powering on your computer. When anything goes wrong, the computer produces a new sequence of beep sounds so that the user may decode the beep code and figure out what went wrong.

Your computer or motherboard documentation will identify the many sorts of beep codes that your computer creates when it encounters a problem. See if you can figure out what the beep code means.

Solution 7: Perform a RAM checkup

The most common cause of no display on the monitor after turning on the computer is a lack of RAM. If your computer has two RAM sticks, remove one of them before turning it on. If the monitor displays something, the RAM stick you removed may be destroyed.

After removing the first RAM stick, place the second one in the same slot and switch your computer on to confirm. The RAM slot might be defective at times. By placing both RAM sticks in one slot and then the other, you may determine whether your RAM or RAM slot is defective. Consider cleaning the RAM stick if it is unclean or rusted.

Solution 8: Reinstall your RAM

This issue might potentially be caused by a bad connection between your RAM and motherboard. You’ll need to reinstall your RAM in this instance. Here’s how to do it:

  • Turn off your computer by pressing and holding the power button.
  • Disconnect the power supply’s AC power cord, then open your computer casing.
RAM sticks in the motherboard
  • Remove your RAM from the memory slot on your motherboard.
  • Replace your RAM in the slot.
  • Turn on your computer after connecting the AC power cord to the power supply.

Solution 9: Remove external hardware

If you don’t hear any beeps while the computer starts up, unplug any external hardware devices. To get started, the motherboard simply needs the CPU and its fan, RAM, and SMPS. The motherboard does not require any additional hardware to start, including SSDs, HDDs, external cards, and other external devices like printers and scanners.

As a result, you may unplug all of the additional gadgets and restart the computer. If the computer starts up normally, try reconnecting the removed devices one at a time and restarting the machine each time. This identifies which hardware has been damaged.

Solution 10: Check the Graphics card

Users may get a blank screen as a result of a broken graphics card. You might want to double-check your graphics hardware. You can skip this step if your computer does not have a graphics card installed. All graphics tasks are done by your motherboard in this situation.

If the graphics card has not been cleaned in a long time, it might corrode. Alternatively, dust might develop on it, causing communication loss between the graphics card and the GPU. You must now remove the graphics card and restart your computer without it.

For your safety, please remove the graphics card while wearing anti-static wrist bands. This will help safeguard the computer’s sensitive internal components from being harmed by static electricity.

MSI NVIDIA GeForce RTX 3080 graphics card

Connect the video wire from your display to the video port on the motherboard (VGA/HDMI/DVI) to run your PC without a graphics card. If you see something on the screen, your graphics card may be broken. Clean your graphics card with isopropyl alcohol if it’s unclean or rusted.

The majority of the time, graphics cards merely need to be cleaned. After cleaning it, place it in the appropriate slot on your computer and turn it on. Consider changing the graphics card if you don’t receive any output on the screen.

Solution 11: Reset your BIOS settings to default

Your PC may potentially boot with a black screen due to incorrect BIOS settings. You should reset your BIOS to factory settings to check if that’s the issue. Here’s how you can do it:

  • Turn off your computer by pressing and holding the power button.
  • Disconnect the power supply’s AC power cord, then open your computer casing.

  • Using your fingernail or a non-conductive screwdriver, remove the CMOS battery from your motherboard.
  • Wait 5 minutes before replacing your CMOS battery.
  • Turn on your computer and connect the AC power cord to the power source to see whether the problem remains.

Solution 12: CPU and Motherboard checkup

Your CPU or motherboard may be damaged if none of the following solutions work for you. In any event, if these solutions don’t work, you’ll need to hire an expert to fix your computer.
