Computer Screen Goes Black But Computer Still Running [Windows 11 & 10]

It can be frustrating if you find your computer screen goes black but computer is still running. This issue can disrupt your workflow, interrupt your entertainment, and leave you feeling puzzled about what went wrong. Thankfully, there are several troubleshooting methods you can try to fix this problem. Here, we will discuss nine effective ways to resolve the issue of a black computer screen while the computer is still running.

Common Reasons for the Issue

The issue when a computer screen goes black but the computer still running can occur due to a variety of reasons. Some of the most common reasons for this issue are discussed here:

1. Hardware Malfunctions

One of the primary reasons for a black screen on a computer while it is still running can be attributed to hardware malfunctions. This can encompass a range of issues, including problems with the graphics card, monitor, or other internal components. For example, a faulty graphics card may fail to properly display images on the screen, resulting in a black screen despite the computer’s continued operation.

2. Software Glitches and Compatibility Issues

In addition to hardware malfunctions, software glitches, and compatibility issues can also be responsible for causing a black screen while the computer remains operational. This can occur as a result of conflicts between different software programs, outdated or incompatible drivers, or errors within the operating system itself. For example, a recent software update or installation may introduce an unforeseen conflict that disrupts the normal display output, leading to a black screen. 

3. Overheating and Thermal Issues

Another factor why you might find your computer screen goes black but the computer is still running is overheating and thermal issues. Modern computers generate a significant amount of heat during operation, and if this heat is not effectively dissipated, it can lead to thermal throttling and other adverse effects. In some cases, excessive heat buildup can cause components such as the CPU or GPU to exceed safe operating temperatures, triggering protective mechanisms that result in a loss of display output. 

4. Hardware Incompatibility and Upgrades

When users upgrade or modify their computer hardware, they may inadvertently introduce incompatibilities that result in a black screen issue. This can occur when new components, such as a graphics card or RAM modules, are installed without proper consideration for compatibility with existing hardware or system configurations. 

5. Electrical and Power-related Issues

Electrical and power-related issues can also contribute to the occurrence of a black screen on a computer. This can encompass a range of potential problems, including issues with the power supply unit (PSU), electrical surges or fluctuations, and faulty power cables or connectors.

A failing or inadequate power supply can lead to instability in the computer’s power delivery, potentially resulting in intermittent black screen episodes. Similarly, electrical surges or fluctuations in the power grid can impact the computer’s components and lead to unexpected behavior, including a loss of display output. 

6. Operating System and Firmware Updates

The installation of operating system updates and firmware upgrades can introduce changes that affect the normal operation of the computer and potentially lead to a black screen. This can occur when updates contain errors or bugs that impact the display subsystem or other critical components of the system. 

7. Environmental Factors

Environmental factors, such as dust accumulation, temperature extremes, and exposure to moisture, can also contribute to the occurrence of a black screen on a computer. Dust accumulation within the computer case can impede airflow and cooling, leading to increased operating temperatures and potential thermal issues that result in a black screen.

Similarly, exposure to high temperatures or direct sunlight can impact the performance and reliability of the computer’s components, potentially leading to unexpected behavior, including a loss of display output. 

8. Hardware Wear and Aging

As computers age and components undergo wear and tear, the likelihood of encountering hardware-related issues, including black screen problems, increases. This can be attributed to the degradation of internal components, such as capacitors, connectors, and other critical elements that may impact the reliability and performance of the system.

For example, aging capacitors on the motherboard or graphics card can lead to instability in the power delivery and signal processing, potentially resulting in a black screen.

Computer Screen Goes Black But Computer Still Running? 9 Ways to Fix

There are several ways by which you can fix the issue if your computer screen goes black but computer still running. Here are some of the most effective ways to fix this issue:

Method 1: Check the Power Supply

The first step in troubleshooting a black screen issue is to ensure that your computer is receiving adequate power. Check if the power cable is securely connected to both the computer and the wall outlet. If you are using a laptop, ensure that the battery is charged. Sometimes, a loose connection or insufficient power can cause the screen to go black.

Method 3: Update Graphics Drivers

Outdated or incompatible graphics drivers can often cause screen-related issues. To update your graphics drivers, follow these steps:

Step 1: Press the Windows key + X and select “Device Manager.”

update graphic drivers

Step 2: Expand the “Display adapters” category, right-click on your graphics card, and select “Update driver.”

Step 3: Choose the option to search automatically for updated driver software and follow the on-screen instructions.

Method 4: Disconnect External Devices

Sometimes, external devices connected to your computer can interfere with its normal functioning and may be the reason why your monitor randomly goes black. Disconnect all unnecessary devices, such as USB drives, printers, or external monitors. Then, restart your computer to check if the black screen issue persists. If the problem is resolved, you can reconnect the devices one by one to identify the problematic one.

Method 5: Boot into Safe Mode

Booting your computer into Safe Mode can help determine if the black screen issue is caused by a software problem. To boot into Safe Mode, follow these steps:

Step 1: Restart your computer and press the F8 key repeatedly until you see the Advanced Boot Options menu.

boot into safe mode

Step 2: Select “Safe Mode” using the arrow keys and press Enter.

Step 3: Once in Safe Mode, check if the black screen problem still occurs. If not, it indicates that a software conflict is causing the issue.
