It’s confusing to see a blank screen when you turn on your computer. Of course, the first thing to do is restart your computer and check if the display cables are intact. But if that doesn’t help, you’ll have to roll up your sleeves and troubleshoot a few issues to fix this problem.
Most of the time, the problem is with loose cables and hardware failure. There are also cases where improper software configuration, especially after installing updates, prevents the display from turning on. Here is how you can fix the problem.
1. Confirm if the monitor is on
Check the connection and operation of your monitor if your computer turns on, but nothing appears on the screen. Check if the monitor has turned on and if the power cable is properly inserted.
Also check the power supply. Check that the cables connecting to your monitor are not loose or damaged. If the connections are correct, try turning the monitor off and then on again. To do this, long press the power button. You can then wait a few minutes and then turn it on again.
If that doesn’t help, use a different and new power cable for your monitor and test the current cable on a different monitor. If none of these solutions work, it’s time to try some other fixes.
2. Check the display cable connections
The display cable transfers electronic signals between your computer and your monitor. Therefore, any problem during the transmission process may result in a blank screen.
If you suddenly get the blank screen, check the condition of the connectors on the display cable (VGA, DVI, HDMI, DisplayPort). Watch out for damaged or broken parts that may be causing the problem. Twisted or mutilated display cables can also wear out over time and fail to transfer signals properly.
3. Perform a RAM check
A bad connection between your RAM and the motherboard can turn on the computer, but no display problem in Windows 10. To troubleshoot RAM problems, perform a quick check.
First, clean the RAM. Wipe off any dust, dirt or corrosion that is blocking the transmission. Next, remove the RAM sticks from your computer. Insert the RAM modules one at a time to confirm if any of them are causing the error.
If your device detects problems with a certain RAM key, you need to fix it. Also, check the conditions of the RAM slots. Try different RAM keys in different locations to identify faulty components that might be causing the problem.
4. Disconnect external devices
External devices connected to your computer can also be the cause of the blank screen. To resolve this issue, you can disconnect and then reconnect the devices.
To safely eject devices, first shut down your computer by long pressing the power button. You can then remove the mouse, scanner, printer, and any other external device from your computer. Then turn on your computer.
Try to connect the devices one by one to determine which one is causing the problem. Then properly replace the peripherals.
5. Troubleshoot the beep code
Your computer has a specific beep code that is emitted when a hardware error occurs during startup. Due to the uniqueness of this beep, you can easily identify the cause of a computer problem by the sounds that are playing.
To do this, first restart or turn on your computer. Then pay attention to the sound generated by the computer. Note the number of beeps and the duration of the sound. Then use the motherboard manual to decode the cause of the sound. You can also consult an expert to better understand the meaning of the different beeps.
6. Reset your computer’s BIOS
If you tinkered with the BIOS or flashed a beta, it could lead to a blank screen error on your monitor. To reconfigure your BIOS settings, consider reverting to the default settings. To start this process, shut down your computer.
Turn on your computer and press the appropriate keys (usually F2 or F12 or Delete) to enter BIOS mode. When your computer boots into BIOS, look for the option to reset BIOS settings to factory default settings. After that, you will need to restart your computer. Hope this should fix the problem.
Resolve no display
The above solutions should help to fix the computer turning on but no display problem in Windows 10. It is also recommended to seek help from repair computers if you have no expertise in them. process. Also, seek assistance from people or companies with hardware components that you might need to test the functionality of your components.
