Because there are various reasons why your computer isn’t showing anything on the screen, it’s critical that you follow the troubleshooting steps below.


Double-check your setup if you built the machine yourself! This issue is mostly certainly caused by a setup mistake rather than broken hardware.

Step 1: Put the Monitor to the Test

Check all PC-to-monitor connection cords and make sure your display is in good working order before you start debugging difficult and time-consuming issues. Check to see whether your VGA/HDMI cable is loose, which might be causing the display to refuse input from the computer.

1638848383_577_15-Solutions-To-Fix-Computer-Turns-On-But-No-DisplayThe Monitor is being tested.

If your computer is working properly, but your display isn’t, it’s quite probable that the monitor is the issue. You might test another monitor that seems to be in good working order.


If your computer has both VGA and HDMI connectors, check out both on your display. If it doesn’t work, try a different cable that is comparable and has been shown to work.

Restart the computer in the second step.

Some issues may be resolved simply by restarting the computer. Try pushing the reset button, or make sure the computer is turned on from the beginning.

1638848384_534_15-Solutions-To-Fix-Computer-Turns-On-But-No-DisplayReboot the computer

Frequently, the computer will seem to be “not turning on” when, in reality, it is having trouble waking up from Windows’ Standby/Sleep or Hibernate modes.


You may switch off your computer while it is in Standby/Sleep mode by holding down the power button for 3 to 5 seconds, especially for laptops/tablets/PCs without a reset button. Restart the computer once it has been fully shut off to see whether it can turn on properly.

Step 3: Look for a Beep Code (if there is one).

It will be simpler to determine the area of the computer issue if you are fortunate enough to hear a beep code from your computer. The cause of your computer issue will be revealed via a beep code. If you hear a beep, go here for a guide to the beep code.

1638848385_330_15-Solutions-To-Fix-Computer-Turns-On-But-No-DisplayIf there is a beep code, look it up.

When the computer starts up, pay close attention for the beep code. If you miss anything, just restart your computer and listen again. At the very least, rebooting or restarting the computer a few times will not exacerbate the issue.

Cleaning the RAM Connector (Step 4)

1638848385_186_15-Solutions-To-Fix-Computer-Turns-On-But-No-DisplayThe RAM Connector should be cleaned.

Remove the RAM from the motherboard, then wipe off the RAM connection with a cotton swab dipped in rubbing alcohol (IPA / isopropyl alcohol). Wait for the RAM to dry before plugging it back into the motherboard and restarting the computer.

Cleaning the legs or RAM connections using a rubber eraser is also possible, however some experienced technicians advise against it.

Step 5: Kembali CMOS Reset

Perform a CMOS reset. Clearing the BIOS memory on your motherboard will return your BIOS settings to their original state. Your PC may not switch on for an extended period of time due to a BIOS misconfiguration.

1638848386_463_15-Solutions-To-Fix-Computer-Turns-On-But-No-DisplayKembali CMOS Reset

You may remove the spherical battery on the motherboard of a PC and then replace it after some time.

Also, if you’ve ever reset CMOS using jumpers, put those abilities to work now.


If resetting the CMOS cures your issue, make sure you try it again whenever you alter a BIOS option. So, if the issue reappears, you’ll know which update is to blame.

Step 6: Make sure the switch’s power supply is working.

If this is the case, double-check that the power supply voltage switch is adjusted properly. Your computer may not start on correctly if the power supply’s input voltage does not match the specifications in your country.

15-Solutions-To-Fix-Computer-Turns-On-But-No-DisplayExamine the switch’s power supply

If this switch is defective, your computer should not power on at all, but improper voltages might also create computer difficulties. This little switch is used to change the power supply’s input voltage from 110v/115v to 220v/230v. It should be adjusted to 220v/230v in India.

Step 7: Reinstall every component of your computer.

Unplug all cords and hardware from your computer, then reconnect it. One or more wires or pieces of hardware may have come free. Power cables, data cables, memory, expansion cards (VGA, sound cards, and so forth) need all be unplugged and reinstalled.

1638848387_876_15-Solutions-To-Fix-Computer-Turns-On-But-No-DisplayAll computer components must be reinstalled.


Ensure that all cables are correctly reconnected. Even if the computer is powered on, if the extra VGA Card has been deactivated, utilizing it will not show anything to the monitor. Try connecting to the proper VGA port for this.

Additionally, disconnect and reconnect the keyboard and mouse wires. Although this is unlikely to be the source of the issue, we should keep it in mind when replacing all computer components.

Step 8: Replace the CPU.

If the preceding options don’t work, remove and then reinstall the CPU if there’s any chance it was loose or improperly installed.

1638848387_203_15-Solutions-To-Fix-Computer-Turns-On-But-No-DisplayReplace the CPU.


Because the odds of fitting the CPU improperly or loosely are low, installation is a delicate operation. This isn’t a major issue if you’re cautious!

Step 9: Make sure there are no short circuits.

Check to see whether your PC has an electrical short. This is often the source of typical computer issues.

1638848388_575_15-Solutions-To-Fix-Computer-Turns-On-But-No-DisplayExamine for a short circuit.


It is critical that you thoroughly check the guts of your computer for anything that could be creating a short circuit. If you don’t spend the effort to solve these problems, you can wind up with unnecessary hardware replacements.

Screws are a common source of electrical short circuits in computers, since they make direct contact with metal on the motherboard or other internal components. Almost every component within the chassis is secured with screws, including video cards, sound cards, hard drives, optical drives, and so on. If your PC makes a rattling sound, it might be a loose screw; remove it using a little, long screwdriver.

Cables that have lost their protective coating and come into direct touch with internal components may also create electrical short circuits within computers.

Step ten: Check the power supply


1638848389_215_15-Solutions-To-Fix-Computer-Turns-On-But-No-DisplayCheck the power supply

Just because your computer is turned on does not indicate that its power supply is operational. Power supplies are more likely than any other hardware element to create difficulties, and they are often the reason of computers not operating correctly. Replace it with a power supply from another computer to see if it works.


This is not a stage to be skipped! Don’t assume that just because your computer can ” switch on ” that your power supply isn’t an issue. Power supplies may operate in a range of environments, and those that aren’t totally functioning should be changed right away.

Step 11: Use the least amount of hardware possible.

Start your computer with just the most essential components. The idea is to temporarily disable as much hardware as possible while keeping the machine functional.

  • Go to Step 12 if your computer boots up and can continue to operate with just essential hardware.
  • Continue to Step 13 if the machine does not start up correctly.

1638848389_122_15-Solutions-To-Fix-Computer-Turns-On-But-No-DisplayUse the least amount of hardware possible.



This stage is simple enough for anybody to complete without the need of any special equipment, yet it may give a wealth of useful information. If the computer still won’t switch on after attempting all of the preceding procedures, this step should not be omitted.

Step 12: Examine Any Other Hardware

When all of the critical hardware has been installed and there are no issues. Reinstall any extra hardware that has been removed. Re-test your computer (restart) after each hardware installation to ensure that none of the hardware is faulty.

1638848390_529_15-Solutions-To-Fix-Computer-Turns-On-But-No-DisplayAdditional Hardware should be checked

Because your PC is simply powered by the most essential hardware, all of the components are in good working order. This indicates that one of the removed pieces of hardware is causing the computer to malfunction. You’ll locate the hardware that’s causing your trouble by putting it into your computer and testing it after each installation. Once you’ve found it, replace the broken hardware with new or functional hardware.

Step 13: Use a PC Analyzer or a Self-Test Card with Power On.

Use a PC Analyzer or a Power On Self Test card to test your computer. A POST card can assist determine which hardware is the issue if your computer is still not showing anything on the monitor, even with just the basic gear installed.

1638848390_427_15-Solutions-To-Fix-Computer-Turns-On-But-No-DisplayOn the Self-Test card, use the PC Analyzer Power.

A POST card is extremely reasonably priced. If you don’t have one and don’t wish to get one, go to Step 14.

Step 14: Verify the Hardware Requirements

Replace each piece of hardware in your computer one at a time with the same or similar hardware that has been ” known to be in excellent working order “. Perform a test every time you replace a component to determine which hardware is the source of the issue.

1638848391_359_15-Solutions-To-Fix-Computer-Turns-On-But-No-DisplayCheck the Minimum Hardware Requirements


The majority of computer users do not have a computer components collection. My recommendation is to return to Step 13. The PC Analyzer / POST card is a cost-effective alternative to purchasing all of the computer’s replacement components.

Step 15: Seek professional assistance

Finally, if everything else fails, you may need to seek expert assistance from a computer service center or an authorized computer service provider.

Continue reading:


Unfortunately, without a POST card and new components, you won’t be able to determine which hardware is malfunctioning. In certain situations, you have no option except to depend on the resource’s owner, either a person or an organization.

In theory, after the last step is completed, your computer should be able to function normally again.
