There can be many reasons why a computer screen may intermittently go blank, including hardware and software issues. Below are the most common causes and their suggested remedies.
1. Inadequate Power Supply
If your computer’s power supply is inadequate, that means it does not have enough power to supply all of the components in your system. This can lead to parts of your system, such as the monitor, being partially or fully disabled. The best way to remedy this issue is to increase your computer’s wattage by purchasing a more powerful power supply.
2. Faulty Graphics Card
A faulty graphics card can also cause your computer’s display to go blank intermittently. A strong indicator of this issue is if the display becomes distorted and then goes blank. If this is the case, you should check the connections between your graphics card and monitor. If everything is connected correctly, the best solution is to replace your graphics card.
3. Bad Cables/Connectors
If there are loose cables or connectors between your computer and monitor, this can cause your monitor to go blank intermittently. To fix this issue, you should make sure all the connections are securely in place and that none of the cables or connectors are damaged or frayed.
4. Software Issues
Sometimes, software issues can lead to your computer screen intermittently going blank. One example of this is an outdated device driver or an incompatible hardware configuration. To fix these types of issues, you should update your operating system and any device drivers that might be out of date. Additionally, you should make sure your hardware configuration is compatible with the software you have installed.
5. Overheating
If your computer is overheating, this can cause your monitor to turn off for brief periods of time. To avoid this issue, make sure your computer is properly ventilated and that there is no dust or debris blocking the fans or vents. You should also check the temperature of your computer’s components to make sure they are not running too hot. If they are, you may need to purchase a cooling case or install additional fans.
6. Flickering
If you experience flickering on your monitor, this could be a sign of a failing monitor or an issue with the cable connecting your monitor to your computer. To fix this issue, ensure that both the monitor and cable are working properly and securely connected. If the issue persists, it may be time to replace your monitor.
In conclusion, there can be many reasons why your computer screen may intermittently go blank. Out of the aforementioned causes, inadequate power supply, a faulty graphics card, bad cables/connectors, software issues, overheating, and flickering are some of the most common. To remedy these issues, take the appropriate steps based on the individual cause.
