Computer Black Screen: Causes and Effective Solutions

Undoubtedly, many people encounter the situation where their computer displays a black screen, leading to interruptions in work and study. In the following article, let's delve deeper into this issue with Mytour Blog and explore various ways to fix the computer black screen problem during startup. 

Description of laptop black screen error

The black screen error often occurs when your computer is not using genuine Windows software. You may encounter this issue during usage or even immediately after installing Windows. This can disrupt your computer usage and cause a lot of inconvenience.

Detailed description of some signs of black screen error on laptop:

• The screen goes black immediately after booting up the computer.
• Displays the message 'This copy of Windows is not genuine' in the bottom right corner of the screen.
• Unable to change the laptop wallpaper.
• Unable to access the Windows system even though components like the hard drive and mouse cursor are functioning normally.

Causes of laptop black screen 

Firstly, to understand how to accurately and effectively resolve the issue of computer black screen unable to enter Windows, we need to delve into the specific causes of the problem.

Power Supply

This reason is quite simple yet very common. The power cord of your computer monitor may be loose or you may have forgotten to connect the computer to the power outlet. Unstable power supply can lead to burning of power supply components, CPU, RAM, or chipset. This will cause the computer to not power up, and even lead to some other serious errors. So, stay calm and check the power supply, and fix it immediately if possible!

Graphics Card

The graphics card is responsible for handling image-related issues such as color, resolution, display quality, etc. If your laptop screen doesn't turn on, the cause may be a faulty graphics card.

Overheating

Exceeding power capacity and rapidly increasing temperature are also causes of a computer experiencing a black screen. When manufacturing computers, manufacturers typically set up some circuits to allow the machine to automatically shut down if components operate too much and the temperature rises too high.

Therefore, when your screen suddenly goes black, check if the machine is overheating. If it's overheating, wait for it to cool down before restarting to see the result. Additionally, consider upgrading your computer to avoid overloading and regularly maintain your computer, replacing thermal paste for the CPU.

Encountering Issues with RAM

The black screen error could be the result of issues occurring with the RAM, such as loose RAM slots or excessive dust buildup. In such cases, you can try troubleshooting by removing the RAM, cleaning it thoroughly, and reinserting it to check for the error. Alternatively, you can try inserting the RAM into a different slot to determine if the issue truly originates from the computer's RAM.

When removing RAM for cleaning, you can use one of the two most basic methods:

• Method 1: Use a soft cotton swab soaked in alcohol and gently wipe the RAM slots (Never use water for cleaning)
• Method 2: Use a cleaning eraser to gently and evenly erase the entire surface of the RAM slots to completely remove dust buildup

Problem with the Hard Drive

If your computer encounters the black screen error and cannot access Windows, there is a high possibility that it is due to a hard drive issue. To address this problem, you need to check if the hard drive is still functioning by placing your hand on it to feel for any vibrations.

If you feel that the hard drive is still functioning, listen carefully to determine if it makes a 'clicking' noise while running. If you hear this sound, it indicates that your hard drive is damaged. In this case, you need to have your computer's hard drive checked immediately. Allowing the hard drive to continue operating in this condition can lead to data loss, scratches on the disk platter, and make it impossible to recover data even if you use a data recovery service.

Note: You can only check the operation of the computer as described above for HDDs. For SSDs without moving parts, you cannot perform this check.

Optimizing Screen Settings for Gaming

One cause of the black screen issue is software errors when configuring game settings. Therefore, you should carefully consider your screen settings to avoid encountering screen errors. Typically, computers freeze at a black screen when switching from small to full-screen mode.

To resolve this issue, restart your computer system and continuously press the F8 key until you enter Safe Mode. At the startup screen, select Enable VGA to allow the computer to automatically detect the appropriate resolution.

Software Conflicts

Errors may occur right after installing an application on your computer, indicating a high likelihood of software conflicts.

Windows Update with Patches from Microsoft

Many users report encountering the black screen error immediately after updating Windows patches from Microsoft, even while using genuine Windows. According to security firm Prevx, this issue stems from Microsoft's patches, although Microsoft itself does not acknowledge this.

Guide to Fixing Black Screen Issue 

If your computer encounters a black screen error while in use, most people will feel confused about how to resolve it and often seek assistance from highly skilled individuals or resort to repair services. However, instead of investing considerable effort and money, you can try troubleshooting it yourself before resorting to the last option of taking it to repair shops. You can attempt to resolve this issue with the following methods:

Using Command Prompt

Step 1: On your computer screen, click on the search icon. Then type cmd.exe into the search box and select 'Run as administrator'.

Step 2: Once the Command Prompt window appears, type the command slmgr/ rearm and then click 'OK'. You have now successfully fixed the error, so check the results.

Step 2: Click on Services and Applications, then select Services. Scroll down and double-click on Windows Update.

Step 3: Next, go to the Startup type section and click on Disabled, then click OK to finish the installation process.

Reload Windows Explorer

When a virus infiltrates your computer, it can directly affect the operating system, rendering your computer unable to reload Windows Explorer. This is the quickest way to regain access to the operating system, and for a more thorough fix, you should consider resetting your Windows operating system.

Step 1: Start your computer and press Ctrl + Alt + Delete, then select Task Manager.

Step 2: Right-click, select File, and click on Run new task.

Step 3: Once the dialog box appears, type Explorer.exe. Now, click OK to continue accessing the Windows screen.

Temporarily disable the dedicated graphics card

Step 2: Press Windows + R and enter the command devmgmt.msc then press OK.

Step 3: Locate Display adapters.

Step 4: Try right-clicking on the line containing the dedicated card, select Disable to temporarily disable this dedicated card and restart to check the result.

Step 5: After booting up, if the issue persists, try disabling the onboard card as well and restart to check the result.

Step 6: If you have disabled both the dedicated and onboard cards and the black screen issue still occurs on startup, then the cause is not the graphics card. At this point, re-enable both cards.
