Since there are several reasons why your PC is not displaying anything on the monitor, it is very important that you read the troubleshooting below.

Notes

If you assembled the computer yourself, double-check your configuration! There is a high chance that this problem occurs due to a configuration error, not due to faulty hardware.

#1: Testing the Monitor

Before you start troubleshooting complex and time-consuming problems, check all PC-to-monitor connection cables, making sure your monitor has no problems. Also check if your VGA/HDMI cable is loose, causing the monitor to not accept input from the computer.

Very likely if your computer is fine, but the monitor is the problem. You can try another monitor that looks like it’s still working.

Important

If your computer has VGA and HDMI ports, try to test each one on the monitor. If that doesn’t work, try using another similar cable, which is known to work.

#2: Restart Computer

Sometimes just by restarting the computer, some problems can be solved. Try pressing the reset button, or make sure everything starts from scratch by turning on the computer.

Often times the computer will appear “not turning on” when in fact it is only having problems waking up from Standby/Sleep or Hibernate mode in Windows.

Notes

Especially for laptops/tablets/PCs without a reset button, you can turn off your computer when the computer is in Standby/Sleep mode by holding down the power button for 3 to 5 seconds. After the computer is completely turned off, restart it and check if it can turn on normally again.

#3: Check Beep Code ( if any )

Assuming, you are lucky enough to hear a beep code from your computer, it will be easier to pinpoint the location of the computer problem. A beep code will tell you exactly what is causing your computer problem. Click here for a guide to the beep code if you hear a beep.

Listen carefully for the beep code that sounds when the computer starts up. If missed, simply restart/restart your computer, and listen again. At least restarting or restarting the computer a few times won’t make the problem worse.

#4: Clean the RAM Connector

Remove the RAM from the motherboard, then clean the RAM connector using a cotton bud that has been dripped with a little rubbing alcohol (IPA / isopropyl alcohol) . When it’s clean, wait for the RAM to dry, then plug it back into the motherboard, then restart the computer.

Cleaning the legs or RAM connectors can also be done using a rubber eraser, but is not recommended by some professional technicians.

#5: Reset CMOS Kembali

Do a reset on the CMOS. Clearing the BIOS memory on your motherboard will restore their original BIOS settings. A misconfiguration in the BIOS could be the cause of your PC not turning on for a long time.

For PCs, you can remove the round battery on the motherboard and then put it back in after a while.

Also, if you’ve ever used jumpers to reset CMOS, then use those skills now.

Important

If resetting the CMOS solves your problem, make sure you test again every time you change a setting in the BIOS. So if the problem comes back, you will know which change caused your problem.

#6: Check Switch Power Supply

If so, make sure that the power supply voltage switch is set correctly. If the input voltage for the power supply does not match the settings in your country, your computer may not turn on properly.

Your computer shouldn’t turn on at all if this switch is faulty, but inappropriate voltages can also cause computer problems like this. This small switch is used to adjust the input voltage to the power supply either 110v/115v or 220v/230v. In India, it should be set to 220v/230v.

#7: Reinstall All Computer Components

Unplug all cables and hardware in your PC and then plug it back in. It is possible that one or more cables or hardware have been loose. Unplug and reinstall things like power cables, data cables, memory, expansion cards (VGA, sound cards, etc.), and so on.

Important

Make sure all cables are reconnected properly. If the additional VGA Card has been disabled, then using it will definitely not display anything to the monitor even though the computer is turned on. For that, try to connect to the appropriate VGA port.

Also, remove and reconnect the keyboard and mouse cables as well. This is unlikely to be the cause of the problem, but we should not ignore it when reinstalling all computer components.

#8: Reinstall CPU

If the above solutions still don’t work, remove and then reinstall the CPU if there is any suspicion that it may have been loose or may not have been installed properly.

Notes

The chances of installing the CPU incorrectly or loosely are very small and therefore installation is a sensitive task. This is not a big problem if you stay careful!

#9: Check For Short Circuit

Check if there is an electrical short inside your computer. This is very often the cause of common computer problems.

Important

It is very, very important that you take the time to inspect the inside of your computer for anything that could be causing a short circuit. If you don’t take the time to troubleshoot these issues, you may end up with expensive hardware replacements for no good reason.

Electrical short circuits inside computers are often caused by screws, in which case there may be physical contact with metal on the motherboard or other internal components.

Screws are used to secure almost every component inside the case including video cards, sound cards, hard drives, optical drives, etc. Shake your PC, if there is a rattling sound it may be a loose screw, use a small, long screwdriver to help remove it.

Electrical short circuits inside computers are sometimes also caused by cables that have lost their protective coating and made physical contact with internal components.

#10: Test Power Supply

Just because your computer is on does not mean that the power supply in your computer is working properly. Power supplies tend to cause more problems than any other hardware device and are very often the cause of computers not working properly. Try to check by replacing it using a power supply from another computer.

Important

Don’t skip this stage! Don’t think that your power supply isn’t a problem just because the computer can ” turn on “. Power supplies can work in a variety of conditions, and those that are not fully functional need to be replaced immediately.

#11: Use Minimum Hardware

Start your PC with only the most important hardware. The goal here is to temporarily remove as much hardware as possible while still keeping the computer running properly.

  • If your computer starts up and can continue to run, with only critical hardware, go to Step 12.
  • If the computer does not start up properly, continue to Step 13.

Important

This step is easy enough for anyone who requires no special tools and can provide a lot of very valuable information. This step should not be skipped if after trying all the previous steps, the computer still does not turn on properly.

#12: Check Additional Hardware

When the most important hardware is installed and there are no problems. Proceed with reinstalling any additional hardware. Re-test your computer (restart) in every installation of one hardware, to check whether every hardware installed is problematic or not.

Since your PC is powered by only the most important hardware, the components work properly. This means that one of the additional hardware removed is causing the computer problem. By installing that hardware into your computer and testing after every single hardware install, you’ll find the hardware that’s causing your problem. Once you find it, replace the problematic hardware with a new one or one that is still working.

#13: Use PC Analyzer / Power On Self Test card

Test PC using PC Analyzer / Power On Self Test card. If your computer is still not displaying anything on the monitor, even with only the essential hardware, a POST card will help identify which hardware is the problem.

The price of a POST card is very affordable. However, if you don’t have one and don’t want to buy a POST card, go to Step 14.

#14: Check the Minimum Hardware

Replace each hardware in your computer one by one with the same or equivalent hardware which has been ” known to be in good condition “. Do a test every time you replace a component, to find out which hardware is the problem.

Notes

Most computer users do not have a collection of computer parts. My suggestion is to go back to Step 13. The PC Analyzer / POST card is inexpensive and is the most reasonable approach to buying all the computer spare parts.

#15: Professional Help

Finally, if all else fails, you may need to seek professional help at a computer service center or from an authorized service provider for your computer.
