Check the Basics of Fix a Computer That Turns On but Shows No Display
Let’s first go for the simple things before trying any complex solutions. Indeed, that is often likely because of a basic problem that the operations overlook.
Power Supply:
Firstly, ascertain whether your computer is properly plugged in to fit the power socket. Cross-check the connecting plug to ascertain whether it has been well-plugged. You can see that the plug is in most of the time, but it’s not firm. Also, check whether the power outlet is functional by the use of another device.
Monitor Connection:
Next, make sure the monitor is actually turned on. This is very basic, but sometimes the most basic issues are skipped. Ensure the monitor’s cable is well placed in both the monitor itself and the computer. If it is loose or out, then your screen will be blank.
Inspect the Hardware
If everything seems okay with the basic checks, it’s time to look inside your computer—not that scary.
RAM:
Without RAM, your computer would definitely be a limp performer. A RAM module might sometimes get loose. Power down your computer and remove the plug from the wall socket to reseat. Open the case and remove the RAM module. Now, fit it back properly into the slot. Most of the time, just that would solve the problem.
Graphics Card:
The graphics card tries to be a part of displaying any image on your screen. But your monitor doesn’t display anything if the connection isn’t good. You may check this by turning off your computer and opening it. Find where your graphics card is.
Usually, it just sits down there with screws. You may make sure it’s been fixed with some screws on the bottom. If it doesn’t hold tight, you may pull it out and put it down carefully again.
Test with Different Components
Sometimes, the problem isn’t with your computer but with external components.
Monitor:
Please test it by connecting another monitor to your computer. If it works, your monitor might be a dud; at least that way, you can rule out the doubt of a malfunction in the monitor or the computer.
Cables:
Exchange the cable of the monitor with another one. Sometimes, the cables have been damaged or worn out over time, causing a connectivity situation. If the new one fixes the problem, you have your culprit.
Listen for Beeps
Often, beep codes are encountered during the bootup of your computer. By listening to these beeps, one can determine what is wrong.
Beep Codes:
The beeping sounds are part of the series of sounds that your computer normally gives out when the power is put on. Each sound matches a different issue. For example, one long beep followed by two short beeps could indicate a problem with the graphics card.
Check your computer’s manual or the manufacturer’s website for a list of beep codes and their meaning. Accordingly, recognizing a certain beep pattern might point you in the right direction.
Reset the BIOS
The BIOS (Basic Input/Output System) is crucial to your computer’s startup process. Resetting it can sometimes resolve display issues.
BIOS Explanation:
The BIOS initializes and tests your hardware during startup. If something goes wrong, resetting the BIOS can help. To reset it, turn off your computer and unplug it. Open the case and locate the CMOS battery, a small, round battery on the motherboard. Remove the battery for about five minutes, then reinsert it. This will reset the BIOS to its default settings.
Check the Motherboard
If the problem persists, it might be with the motherboard.
Visual Inspection:
Carefully inspect the motherboard for visible damage, such as burnt components or loose connections. Look for anything that seems out of place.
CMOS Battery:
The CMOS battery keeps the BIOS settings intact. If it’s dead, your computer might not boot properly. To replace it, turn off your computer and unplug it. Remove the old battery and insert a new one. Make sure the new battery is of the same type.
Seek Professional Help
If you’ve tried all the above steps and your computer still won’t display anything, it’s time to call in a professional.
When to Consult an Expert:
If you’re uncomfortable opening your computer or the problem seems beyond basic troubleshooting, seek professional help. A qualified technician can diagnose and fix more complex issues.
Tips on Choosing a Reliable Technician:
Look for reviews and recommendations. Choose a technician with good ratings and positive feedback. Ask for a clear estimate before any work begins to avoid unexpected costs.
