PC No Display – How to Fix a PC Without a Display

If your PC is on, but there is no display, it could be due to hardware or software issues. Sometimes, a PC will start without a display after you plug in an external device like a monitor, keyboard, or mouse. Other times, the problem could be caused by RAM and BIOS settings. If you have encountered this issue before, here are some simple steps you can take to fix it. Read on to learn more.

Problems with pc’s display

One of the first things to try when your PC displays strange images is to restart the computer. Most computers have some form of power indicator, so turning off the computer monitor may fix the problem. But if you don’t see one, your display is probably dead or not receiving power. If that doesn’t fix the issue, it’s likely to be the video card, so check its age. Another simple test is to reset the display settings.

Another easy way to determine what’s wrong is to connect an external monitor. This can help you narrow down the problems, such as the video card, and video settings. Before you try this step, make sure the monitor and the computer’s display cables are connected securely. CyberPowerPC’s article titled “How to Connect a Monitor to a PC” can help you do this. If this doesn’t solve the problem, you can replace your display.

If you’re experiencing issues with your display, check the display cables and the screen itself. If the LCD screen is damaged, you may see color mismatches or flickering. If you see horizontal or vertical lines, it’s most likely a hardware issue. If you’re still unable to resolve this issue after trying a few different troubleshooting methods, you can try replacing the display. But if that doesn’t work, you’ll probably need to get your PC’s hardware fixed.

If you’ve checked all the other peripherals, but still can’t resolve the problem, it’s possible that the display is the problem. Try starting your system in “Safe Mode” and adjusting the refresh rate and resolution. Holding a flashlight right in front of your display may help you diagnose the problem. If the monitor still won’t show anything, it might be the screen, or backlighting. If it’s the latter, you’ll need to replace the screen.

Common causes

There are many reasons why your PC won’t display a display when it boots up. One of the most common is a faulty RAM stick or CMOS battery. If you don’t know how to replace it, you should check your motherboard’s BIOS settings and replace them if necessary. If none of these methods work, you can try resetting the BIOS. The BIOS controls the hardware settings of the computer and will determine which components need to be replaced or upgraded.

Another cause of a no-display problem is a conflict with a specific peripheral. You may not have the latest drivers for your speakers, camera, or keyboard. If it’s the latter, try reconnecting each peripheral and updating the drivers for each. In some cases, this solution might not be successful, but if it does, you can try replacing the troublesome device with one that’s compatible. Some other common PC no display causes include a problem with power saving mode.

The power cable is another common cause of a no-display problem. If your PC’s power supply is working, then it’s likely that the monitor is. If it is, try using a different data cable. You may need to replace the cable or the monitor itself. In addition to resetting the monitor’s power supply, you should unplug any unnecessary hardware connected to the PC. Disconnecting these peripherals may help your PC power on normally.

The display driver might be the culprit. Sometimes, a bad video/graphics card can cause this problem. If the monitor is working in a different computer, it’s possible the video/graphics card is the problem. If these fail, you should consider calling a computer geek to fix it for you. Otherwise, if you’re unsure what’s wrong with your PC, try the suggestions below. If none of these solutions work, you may need to replace the graphics card or the video card.

To identify the culprit, check your computer’s video cable connections. If nothing seems wrong, try connecting the video cables and blowing into the ports. If the problem persists, it’s likely that a component on the motherboard is damaged or has failed. If all else fails, you can try replacing the video cable or using a laptop with an external monitor. Either way, you may be able to get an image on the screen again.


PC no display problems are frustrating. Even if you can hear the fan running, you may not see any visible screen. The problem can also occur when you can’t get a signal from the monitor. Whatever the reason, there are several possible solutions to the PC no display problem. Before trying any of these fixes, remember to ground yourself. Once you’ve grounded yourself, you can proceed to updating the necessary drivers. You’ll then see a full list of your devices and drivers, including the ones you need to update.

The first solution to the problem is to check the hardware connection points. You should check all hardware connection points, including the CPU socket, RAM module slots, PCIe slot for the GPU, and SATA or M.2 ports. If they’re clean, acetone can solve this problem. If your PC is brand new, you can try this solution. Make sure to plug in the power cable before attempting to repair the PC.


If your computer has a no-display problem, the first thing to try is to update the device drivers. If the problem persists after an update, you may need to power cycle your PC. You can also try to repair your PC in Safe Mode, by performing System Restore, or by resetting. You should be aware that these options are not always effective, so most users try to perform a system reset. This is often the only option that can fix the problem.

The next step is to connect another monitor to the computer. You should try to connect the second monitor to your PC to check if the signal comes through. If the other monitor displays the same picture, it is likely to be a defective monitor. You should replace the monitor if possible. If the problem persists, you should check the video cable and connectors. Be sure that the cable is connected tightly. Check if the connectors have any bent pins. You may need to straighten the bent pins using a small metal tube.

If you have an original graphics card, it may be the problem. If you have a spare, you can connect it to the motherboard’s display output. If it still doesn’t work, replace it with a new one. If this doesn’t solve the issue, you can try the solutions listed above. But if these fail, try a different part of the computer. You may have a damaged or faulty video card, which must be replaced.

The last step is to ensure that the monitor is properly connected to the motherboard and GPU. If the monitor is not connected, the computer may be unable to send video to the display. Another problem you should check is that the brightness of the system has been set to a low level. Using the brightness hotkey, you might accidentally adjust the brightness. If that doesn’t work, it’s best to hold down the power switch for a few seconds.

Another problem that can cause a PC to show no display is memory problems. If you’re able to isolate the cause of this issue, you can begin troubleshooting your system. If you have an old computer, you may be able to download a manual from the internet that details what you need to do. You can also try stress-testing the computer to check if it’s an external problem.
