When you turn on your computer, you expect to see the display on the monitor and the keyboard light up. However, in some cases, you may encounter a scenario where the computer turns on, but there is no display on the monitor or keyboard. This problem can be frustrating, especially if you need to use your computer urgently. In this article, we will discuss the possible causes of this issue and how to troubleshoot it.
What Causes No Display on Monitor or Keyboard But Computer Turns On
First, let’s examine the potential causes of this problem. Several factors could contribute to this issue, including hardware problems, software issues, and user error. Here are some of the most common causes:
- Faulty graphics card: One of the most common reasons for a computer turning on with no display on the monitor is a faulty graphics card. The graphics card is responsible for rendering images on the monitor, and if it’s not working correctly, it could cause the display to be blank. The easiest way to check if the graphics card is causing the problem is to try and connect the monitor to another computer. If the monitor works on another computer, then the problem is likely the graphics card.
- Loose cables: Another possible cause of the problem could be loose cables. Sometimes, cables connecting the monitor and the computer may become loose or disconnected, causing the display to be blank. Check that the cables connecting the monitor to the computer are properly connected and secure.
- Damaged monitor: The monitor may be damaged or malfunctioning, resulting in no display. Try connecting a different monitor to the computer to see if that resolves the issue.
- Corrupted operating system: In some cases, a corrupted operating system could be the cause of no display on the monitor. This can happen if the computer crashed during an update or if there is a virus on the computer. To fix this, try booting the computer in safe mode or using a recovery disk.
What Should You Do to Fix the Issue?
Now that we’ve looked at the possible causes of this issue, let’s discuss how to troubleshoot it. Here are some steps you can take to try and resolve the problem:
- Check the monitor: The first thing to do is to check the monitor. Ensure that it is turned on and connected to the computer correctly. Try connecting a different monitor to the computer to see if that resolves the issue.
- Check the cables: Ensure that the cables connecting the monitor and the computer are properly connected and secure.
- Check the graphics card: If the monitor and cables are not the issues, then it’s time to check the graphics card. Try connecting the monitor to another computer to ensure that the monitor is working correctly. If the monitor works on another computer, then the issue is likely with the graphics card. Try removing and re-seating the graphics card to ensure it is properly connected. If that doesn’t work, try replacing the graphics card.
- Boot in safe mode: If the computer is turning on but there is no display, try booting the computer in safe mode. Safe mode starts the computer with a minimal set of drivers and services, allowing you to troubleshoot the issue further.
- RAM reinstalling: Resetting the RAM involves removing and reinserting the RAM sticks to ensure they are properly seated in their slots. This can fix issues caused by loose or faulty RAM.
- Reset the BIOS: Resetting the BIOS involves clearing the CMOS memory, which contains the settings for the motherboard and other hardware. To reset the BIOS, you will need to locate the CMOS battery on the motherboard and remove it for 4 to 5 minutes and then put it back accordingly, or use the BIOS reset jumper if your motherboard has one.
