How to Fix a Computer That Turns on But Displays Nothing

The most basic way to solve the problem of a computer that turns on but does not display anything is to reinstall the computer’s hardware. It can be a hardware issue or a peripheral one. Test the components one by one and make sure they are working properly. If they are not, you might need to buy a new computer. If the problem persists, follow the tips below to solve it.

 

To replace a component that causes the computer to turn on but not display anything, check the RAM. Some of the common reasons why a computer turns on but displays nothing are a loose connection between the motherboard and RAM sticks, faulty memory modules, or clogged memory slots. The memory sticks are those rectangular green sticks that fit into the grooves on the motherboard with two clamps on each edge.

 

You can also check for loose parts. Check the video cable and the memory sticks, and the fan, if your computer has one. Also, the monitor may be damaged and may not display anything. If you do not have the knowledge or experience to repair the monitor, seek help from a technician. If you can’t fix the problem yourself, consider getting a backup hard drive for your computer.

 

To diagnose the problem, the first thing you should do is unplug all external hardware. Your computer should make a low-pitched noise if it is booting up. However, if you hear beeps or other noises while booting up, then there’s a chance that something is wrong. You can find out which component is causing the issue by checking the motherboard’s manual or by purchasing a replacement speaker for your computer.

In addition to unplugging all external devices, you should check the monitor settings. If it doesn’t display anything, you may have accidentally turned off the monitor. In such a case, press the power button several times and see if the problem is resolved. Besides, if the problem persists, try updating the driver of the problematic device or contacting the manufacturer for assistance.

 

If the display is black, it may be due to a faulty graphics driver or LCD display backlight. It is possible to fix the problem by connecting an external monitor. Make sure that the cable connects to the correct video port. If not, the issue may be with the video card. If this is the case, you can try to connect an external monitor to your computer using a VGA or DisplayPort cable.

 

If the monitor is not working, check the power cord. Some monitors have busted or loose cables, and you may need to replace them. The power cord is usually accessible on the back of the monitor. You can also try using a different video cable or another power cable. But if all these attempts fail, it’s best to visit a computer repair shop.
