Part 1. How to Fix Your PC Turns on but No Display
There are 8 solutions to help you fix the problem of “PC turns on but the screen remains black”.

Method 2. Make sure your computer has completely restarted
Ensure that your PC is coming from a completely powered-off state.
Sometimes, your computer will appear to “not be on” when it’s just having problems resuming from either the Standby/Sleep or Hibernate power saving mode in Windows, resulting in your computer is turned on but having no display on the monitor or keyboard.
Tip: While in power saving mode, you can hold the power button down for 3 to 5 seconds to completely power off this computer. After that, turn on this PC to check whether it can boot normally.
Method 3. Verify that the power supply voltage switch is set correctly
If the input voltage for the power supply is not correct (based on your country), the issue of “PC turns on but no display” may occur (You might be interested in this post: What Is a Power Supply Voltage Switch?)

Method 5. Clear the BIOS memory
Your computer problems might sometimes be caused by some BIOS (an acronym for Basic Input/Output System) misconfigurations.
In this case, try clearing the BIOS memory on your motherboard, which will reset the BIOS settings.
Tip: If this method solved your issue - the computer starts but the screen remains blank, make sure any future changes you make in BIOS are completed one at a time so that when the problem returns, you will know which change caused the issue.
Method 6. Reseat the memory modules
If a memory module is loose, the computer might not display an image. In other words, your computer starts but the screen is black.
Now, you can try resetting the memory modules to fix the “PC turns on but no display” issue. Remove the memory module from the memory slot, and then put it back into the slot to get a better connection so that the computer can recognize the memory.

Method 7. Understand LED lights
If your computer makes one or two short beeps before starting, it is telling you that the BIOS startup was successful.
If your computer beeps and does not start, there might be a more serious hardware issue. Now, you’ll probably need to seek professional help from a computer repair service or your computer manufacturer’s technical support.
Method 8. Check Hardware
Take a look at the actual hardware.
Try disconnecting all devices and peripherals like the mouse, external hard drive, speakers, printers, scanners, etc. from the computer. Then, try turning on your computer again.
If that doesn’t work, you might need to check the actual port connectors on the computer and the monitor for damage.
Sometimes, the VGA/HDMI port on the computer could be damaged or bent if a cable connected to it wasn’t properly taken out. Additionally, some people might try to connect a cable to a connection that doesn’t match, which can also end up damaging the gold or silver connectors inside the port.
In this case, you should take your computer to a repair shop to fix the bent or damaged ports.
