Monitor- Although now some people choose to use a laptop, the presence of a personal computer or desktop PC is still needed. In addition, PCs are considered more powerful; durable than laptops. However, computers are still not free from problems, especially if they are ‘old’ and not accompanied by maximum care.
One of the problems that often occurs is that the PC is on, but the monitor is off. For troubleshooting, the first step to take is to disconnect the cable from the storage device. Then, follow how to solve a computer that turns on but does not appear on the monitor below.
Ensure the condition of the computer monitor
Because the problem is the monitor, it is this component that you must pay attention to first. Make sure the monitor is not experiencing interference or damage. The trick is to check the monitor while the PC is running normally—is it working as it should or not? Then, also check the cables that are connected—are they lose or are they connected properly? One of the two cables that you should pay attention to is the power cable that connects the power source and VGA. It could be that your monitor is not turning on because of a loose connection.
Checking RAM memory
RAM memory is temporary storage space on a PC that also affects its performance. If the monitor has a problem, it never hurts to check the state of this component. Move the RAM to another slot if the motherboard has more than one RAM slot. If these steps have no effect, then clean the RAM because it is possible that dirt such as dust hinders its performance. If this method of dealing with a computer that turns on but does not appear on the monitor does not work, install RAM in another computer’s CPU, because the motherboard on the PC you are using could have a problem.
Replacing another cable or VGA card
VGA is the component responsible for computer visualization. If VGA on a PC has a problem, the impact will be felt until the monitor doesn’t want to turn on. There are three ways that can fix VGA problems on your PC: replace VGA with a new one or plug it into another VGA card.
Maintain processor temperature
An important component on a PC that sometimes goes unnoticed is the processor. The processor can be said to be the brain of the computer, so if it is damaged it will definitely have an impact on other components. Don’t use it, you can’t just turn it on. One of the triggers for processor damage is the temperature or the temperature being too hot. So, if your PC is not showing any problems, keep the processor temperature stable. You can use thermal paste or cooling for the processor so it doesn’t heat up quickly and doesn’t interfere with the performance of other components.

Check power supply
An unstable power supply can cause the computer to not appear on the monitor. This is usually caused by frequent surges or frequent power outages.
Motherboard errors can cause the computer not to appear on the monitor screen. Look at the condition of the motherboard, whether there is a swollen capacitor or the transistor cooling plate changing color. If that’s the case, you have to take the motherboard vendor to the service center.
Restore BIOS settings to default
The last step you can take if the ways to deal with a computer that turns on but does not appear on the previous monitor has not worked is to return the BIOS settings or settings to default. The reason is, that the wrong BIOS can trigger interference, including computer monitors that can’t display anything. How to?
To return the BIOS settings to default, remove the CMOS battery and reinsert it into the PC. That way, the BIOS settings on your PC will be the default. However, you must be careful to do so so that other PC components are not damaged.
You can also ask a friend who is an expert to help apply ways to fix a computer that turns on but does not appear on this monitor to reduce the risk of a more severe error.
