Why Does Your Computer Screen Randomly Goes Black?

computer screen randomly goes black

Did you switch on your PC to find that your computer screen randomly goes black? Or maybe it went dark while you were in the middle of doing some work? People find that their system is still getting power in most such cases, but the screen doesn’t show anything.

Many often refer to this as the black screen of death. But you don’t need to stress or worry just now. Know that there can be multiple reasons behind your screen going randomly dark. Here I will tell you all the common reasons behind your black computer screen and how you can fix it. 

So let us begin!

Why Did Your Computer Screen Go Dark Randomly?

First of all, know that there can be multiple reasons behind your computer screen going black or dark. Here are some of the most common ones:

  • Faulty PSU: If your Power Supply Unit or PSU isn’t working correctly, your system might get power, but not in the correct voltage. This can cause the screen to go black. 
  • Power Settings: Know that the power features and settings dictate the powder that will get consumed and when it won’t be consumed. So fine and detailed settings control these syncs. If any of them go out of sync, then your computer might go black. 
  • Unplugged GPU: If there’s a dedicated GPU inserted in your system with the PC monitor connected to it, then you might experience a dark screen as a result of it being damaged or badly plugged in.
  • Bad Drivers: Know that corrupt or outdated graphics drivers can disrupt the communication signals sent to your hardware. This can result in a black screen. 
  • Damaged Video Cable: Know that damaged video cables, whether VGA or HDMI, are the common culprits behind a black PC screen. Also, note that this generally happens when the cables get dislodged or touched. 
  • Overclocking: Overclocking is used by many to boost the core performance of their PC. But overclocking puts more pressure on various components. As a result, your screen can go black due to this. 

How To Fix The Black Screen On Your Computer?

Here I will discuss the fixes for the various reasons behind your black screen. 

Fixing The Video Cable

If the video cables cause the problem, then follow the below steps to check and fix it: 

  • First, turn your computer off. Then unplug your video cable connecting the monitor to the PC. Then check on the video port connectors and cables for signs of damage. 
  • If everything seems fine, then reconnect the cables. If this doesn’t work, you can use another cable to connect the dual devices. For example, instead of the current HDMI cable you have, use a VGA one. 
  • Now restart the PC. The screen should normally be functioning now. 
  • Note that if any of the connectors are damaged, the only way to repair them is by taking them to the repair shop. 

Disable Overclocking

As said in the first section, overclocking puts tremendous pressure on all the components. As such, you need to disable it. Here’s how you can do it: 

  • Go to BIOS and then reverse every setting, especially the voltage one, back to what it was before you overclocked it. 
  • If you feel like that’s too much work, then you can reset it back to factory settings and then increase from there as per your needs. 
  • Now restart your PC. Your monitor should not be dark anymore. 

Check The Power Settings Of Your Computer

Even a slight issue with the power settings might cause the monitor to blackout. Here’s how you can fix it: 

  • Please press on the key which has the Windows logo on it. Now type ‘Power Option’ and then choose Power Options from the list that pops up. 
  • Ensure that your PC’s power plan has been set to the Power Saver mode. This is because this mode will slow your system down and save power. Note that when you enable this option, you will notice that the brightness of your screen and more has been lowered. 
  • Now click on the ‘Change Plan’ option. After this, set your ‘turn off your display’ and ‘keep the PC in sleep’ options to Never. 
  • Now press the key with the Windows logo again. Now type in screensaver before setting the screen saver option to None. 
  • After this, restart the PC. Your computer should generally be working. Note that the steps will be the same whether you are using Windows 7, 8, or 10. 

Fix The Graphics Driver

Damaged drivers can cause your screen to blackout. Here’s how you can restore normal capacity to your system: 

  • There are two ways you can update or change your drivers. One is the manual way, and the other is the automatic way. As you can imagine, the manual way is cumbersome and time-consuming. Also, unless and until you know about every driver in your system and what it does, I would advise you to go for automatic. It will reduce further damage. 
  • To automatically update your drivers, you need a program that will recognize your computer type and then find the right drivers needed for it. One such example of such software is Driver Easy. Once you have installed such a program, you need to run it. 
  • The software will scan your system to find any defective drivers. After that, it will give you the option to update them. So click on the Update option to auto-download the updated versions of those drivers. Then you can manually install the ones you want. 

If you follow these above steps, then you should be able to get your screen back again. But if not, then there might be something more deeply wrong with your PC. As such, I would advise that you take it to a trusted and reliable computer service center for repair.
