If your computer is displaying a blank or black screen, it may be because one of your hardware components is not working properly. You can check to see if the video card, monitor, RAM, or motherboard are all working by checking their symptoms. If any of these components are not working correctly, you may need to replace them.
A recent software issue has caused my computer to crash. I’ll list the more difficult fixes first because they may require more technical expertise or time.
Method 1 – Check Power
If the light is off, the monitor is off and you should not see any message.
If you are having problems with your monitor, there are a few things you can try. First, make sure the monitor is turned on and plugged in. If the monitor is on but nothing is showing up, try pressing the menu button to bring up the built-in monitor controls. If still you have a blank screen, then this could mean there is a problem with your monitor. Even if nothing is connected, you should be able to bring up the monitor menu. If connecting a different monitor does not solve the problem, then there may be a problem with your computer or graphics card. ..
If a separate monitor works fine, but the power supply is bad on the original monitor, then it could be that the power supply is bad on the entire system. Try replacing all of the power supplies in the system and see if that fixes the issue.
If your computer beeps several times when turning on, it may be indicative of an internal problem.
Bad memory can cause the computer to emit beeps. Beeps can also be related to the motherboard, video card, etc. To figure out what the beeps or status lights mean, you will need to consult the PC manufacturer’s manual. ..
If the computer is in standby or sleep mode, you may need to press keys on the keyboard or move the mouse to wake it up.
Method 2 – Check Cables
If you are using a cable that doesn’t screw into the back of your monitor, be sure to check it for any signs of detachment. This includes making sure the cable is plugged in securely and that there are no kinks or bends in it. ..
If you have more than one video card, make sure to connect them in a way that ensures the best connection possible. For example, if you have two video cards, connect them together so that the video is coming from the front of the card and the monitor is coming from the back.
If you have a dedicated graphics card, make sure the monitor is connected to the graphics card and not to the motherboard. By default, Windows is supposed to disable the motherboard graphics automatically when you have a separate graphics card, but sometimes this doesn’t happen. ..
If you have two monitors and connect one to the motherboard and one to the graphics card, then one monitor will end up blank and now you know why.
If you have two video connections, then you can rule out bad cables by connecting the second monitor to the first computer’s video output and seeing if the screen is blank. If it is, then the issue is with the video cable. ..
If you’re having trouble connecting your video device to your TV, try using a different cable. There are multiple types of cables available, like HDMI and DVI, so it’s worth checking to see if one of those works better for your setup. ..
Method 3 – Check Resolution, Display & Source
If you’re having trouble getting your computer to display images or videos on a monitor that’s higher than its native resolution, you can fix the issue by first booting into safe mode. ..
If you have a computer that has a blank screen issue, follow these instructions to fix it.
In most modern versions of Windows, the system actually reverts back to the original screen resolution within 15 seconds unless you click on the Keep Changes button. Also, Windows normally detects the highest resolution your monitor can support and shows only those options.
If you are using an older version of Windows or a really old monitor, you may not be able to see the screen when you plug your laptop in to a secondary display or projector.
You can fix this on laptops by pressing one of the function keys and then pressing the monitor key on the keyboard.
Make sure the input source on your monitor is set to the correct input. Most monitors automatically detect the input source, but sometimes this feature can become disabled. Press the buttons on your monitor to bring up the options and go to Input and switch to the correct input.
Method 4 – BIOS and Recovery Options
If you see the initial boot screen, but Windows does not load, this is likely an issue with your computer’s hardware. ..
In Windows, there is a high chance that it is corrupt. If you have no other choice, you will need to boot into safe mode and then try to repair Windows using System Restore/Automatic Repair or using the Reset or Refresh My PC feature.
If resetting your PC doesn’t work, then I would try system restore or automatic repair first. If either of those don’t work, then I would reset your PC by going to the Windows Control Panel and selecting “reset” under the “System” tab.
Method 5 – Check Hardware
Before you begin any repairs or modifications to your computer, it is important to disconnect all devices and peripherals from the system. This will help prevent any potential damage or issues down the road.
If the computer or monitor doesn’t work, you may need to replace the entire device.
If you’re having trouble connecting your computer to the internet, there are a few things you can do to try and fix the problem. First, make sure that the cable is properly inserted into the port on your computer. Sometimes people try to stick a cable into a connection that doesn’t match and that can end up damaging the gold or silver connectors that you see inside the port. If that doesn’t work, you can try connecting your computer to another network or using a different cable. ..
If you don’t have a graphics card, you’ll need to take your computer to a repair shop in order to fix the bent or damaged ports. Most of the time, they will tell you to simply replace your graphics card.
If you are not a bit technically savvy, or if your computer is not working properly, it is important to check to make sure everything is connected and seated properly. You should have already checked the RAM and the fan on the video card, but you should also make sure that the power cord is plugged in and that the computer is turned on.
Computer problems are becoming more and more common, so it’s important to get your computer serviced if you don’t know how. If you have any questions, feel free to comment. Enjoy!
