When a computer monitor turns off but computer still running, what happens when your computer screen goes black but still running? Well, this is a common problem which has a number of possible solutions. A computer monitor in the computer world stands tall as a monster of technology. From its origins as an electromechanical display connected to the central computer to its present day sleek designs with amazing resolution and comfort, it is hard to think that anything can look more “refined” than these displays. In fact, computers are getting better, more advanced and more powerful all the time. Technology such as monitors is constantly evolving to give users a better experience through easier management of the systems.
The most common is an issue with a power failure within the computer itself. These monitors use power from the wall outlet for its operation so if there is a break in this connection, the monitor is not working. The first thing to check for is a fuse or circuit breaker within the power outlet which can be checked with a meter. It is important to make sure the power is turned off completely before attempting to troubleshoot the issue. If it is already out of order, simply disconnect the power from the outlet and allow the computer to cool down for at least a few minutes.
What happens when your Computer monitor turns off but computer still running?
If the power source is not a problem and the monitor is just off because of other reasons such as an overheating fan within the computer, then it may just need to be cleaned internally. The monitor’s fan should spin up and spin down at regular speeds. If the fan is overheating, then it could be that the monitor manufacturer has not properly tested and equipped the unit with proper cooling fans.
Another possibility is that there is something physically wrong with the power supply of the computer. If this is the case then the monitor may need to be exchanged for a new one. Take note that even though a monitor is an off-the-shelf device and can be easily replaced by any hardware store, there are still specific models that need specific connections and wires to work. Before making a purchase, try to do a quick research on the monitor’s specifications and connection requirements so that you will know exactly what you need to buy or replace. If the monitor manufacturer has not provided any information about its own monitor specifications and cables, then inquire from its technical support personnel about these things so that you will have a clear idea on your computer’s power supply.
Commonly, computers incorporate several power supply devices together in one computer system. Some of these are dedicated to the graphics card and sound card, while there are others that are exclusive to hard disk and CPU (in the case of desktop computers) processing functions. Among the most popular and widely used power supply devices are the ATA or AVR cables that are available in the market in different voltage and plug configurations. The AVR cable is commonly used in connection with hard disk drives, motherboards, sound card and monitor. If you still have no idea on how to connect the cables, just remember that most computer systems have at least one PCI slot for the PCI express cards and another one for the AGP cards (analog) and the random access memory (RAM).
In case your computer is equipped with internal or external video port, then this could also be causing the problem of your monitor turning off but the computer is still running. To determine if this really is the case, shut down the computer and take a look at the power source. If all of the ports are not functioning properly, it could mean that there is damage in one of the connections that are carrying the AC power supply to the computer. In this case, repair the damaged connection and reattach the cable to the other port. It is also possible that the video port itself is not functioning; this can be resolved by replacing the video port with a new one.
However, if the monitor is functioning normally despite having power problems, it is more likely that the problem is with the computer itself. For this case, you will need to troubleshoot the computer using troubleshooting utilities. These tools allow you to determine the trouble spots of your computer and repair them. For example, the monitor might turn on but not actually recognize your keyboard or mouse. You will then be able to see all the trouble codes in the system tray, which allow you to know what the problem is.
If all else fails, then you may have to use an external computer monitor stand to solve the problem. These devices allow you to attach an external monitor to your computer monitor so you can still see what’s going on. Alternatively, you can also use the computer monitor stand to prop up the monitor on a desk so you can view the screen easily. If your monitor still won’t turn on or recognize your keyboard or mouse, then you must first ascertain why it isn’t working. Many times, this problem is caused by a software issue. Simply downloading and installing the latest updates or repairing the various software components should fix this issue.
