Outdated or faulty GPU drivers are the most common cause, leading to a temporary loss of signal. Other possible reasons include the graphics card overheating, a failing power supply, or a damaged monitor. In this article, we will discuss different solutions to solve this issue.
1. Checking HDMI/VGA Cable
A loose or damaged HDMI or VGA cable can cause your monitor to go black. Ensure the cable is securely connected and not damaged to maintain a stable connection. Over time, cables can loosen or wear out, causing signal loss. Replacing a faulty cable or switching to a different port often restores stable video output and prevents disruption. This step helps identify connection issues before trying more complex fixes.
2. Disable Overclocking
Overclocking pushes hardware beyond limits, leading to instability. Disabling it reduces stress on the GPU or CPU, preventing overheating and driver crashes that cause the monitor to go black. Reverting to factory settings ensures safe operation and can resolve display issues. You can check our article on detailed guide on Overclocking. We recommend that you disable all types of overclocking and run your CPU at factory settings. Additionally, ensure that no computer enhancement programs are running, as they might conflict with the OS and graphics.
3. Update Windows
Updating your Windows OS can fix display issues like blackouts by improving hardware compatibility, GPU driver integration, and system stability. The latest build provides optimizations and patches to resolve problems from outdated software and maintain compatibility with new hardware and drivers.
4. Update Graphics Drivers
Outdated or corrupted graphics drivers can cause random black screens by disrupting GPU communications with the monitor. Updating drivers ensures the GPU uses the latest software, with bug fixes and improved compatibility. This resolves conflicts between the GPU and the operating system, restores stable display output, and prevents driver crashes.
5. Check your PSU (Power Supply Unit)
A faulty or insufficient PSU can cause the monitor to go black. If the PSU fails to provide stable power to the GPU or components, it can lead to sudden power losses and display cutouts. Ensure your PSU delivers enough wattage to meet your system’s demands, especially with high-performance components, to prevent blackouts.
6. Uninstall Third-party Programs
Sometimes, third-party software causes the monitor to go black by interfering with system operations. Uninstalling or disabling programs like GPU overclocking tools can resolve conflicts with GPU drivers or display settings and help determine if the issue is software-related.
7. Change Power Settings
Power settings affect energy distribution. Adjusting them prevents the monitor from entering low-power states that cause black screens. Use “High Performance” settings to ensure consistent power to the monitor and GPU, reducing blackouts.
8. Check your GPU
To address random black screen issues, checking the GPU is crucial. A faulty GPU can interrupt the monitor signal due to a bad driver, overheating, or unstable power. Ensure the GPU is seated, not overheating, and drivers are updated. Run stress tests or try the GPU in another system to confirm if it’s the issue.
9. Check for Power Interference/Issues
Power fluctuations can cause a monitor to go black suddenly. Electrical interference or inconsistent power to the monitor or GPU may lead to brief signal loss. To check for power issues, ensure power cables are secure, the power supply provides enough wattage, and test the system on a different outlet or surge protector. This helps rule out power issues and ensures the hardware gets steady power, reducing screen blackouts.
