6 Best Ways to Fix Computer Turning On and No Display in Windows 10

It is surprising to see a blank screen when you turn on your computer. Naturally, the first thing you do is restart your computer and check if the display cables are intact. But if that doesn’t work, you’ll have to roll up your sleeves and fix a few things to fix this issue.

Most of the time, the problem occurs due to loose cables and hardware malfunction. There are also cases where software misconfiguration causes the screen not to turn on, especially after installing updates. You can fix the problem as follows.

1. Confirm if Monitor is On

If your computer turns on, check the connection and function of your monitor, but nothing appears on the screen. Check if the monitor turns on and the power cord is well-seated.

Also, check the power supply. Make sure the cables connecting to your monitor are not loose or damaged. If the connections are OK, try turning the monitor off and on. To do this, long press the power button. You can then wait a few minutes and turn it back on.

If that doesn’t work, use a different new power cord for your monitor and test the existing cable on a different monitor. If none of these solutions work, it’s time to try other fixes.

2. Check Display Cable Connections

The display cable transfers electronic signals between your computer and monitor. Therefore, any problem during the transfer process can cause a blank screen.

If you suddenly get a blank screen, check the condition of the connectors on the display cable (VGA, DVI, HDMI, DisplayPort). Watch out for damaged or broken parts that could be causing the problem. Twisted or crimped screen cables can also wear out over time and may not transmit signals properly.

3. Perform a RAM Check

Poor connection between your RAM and motherboard can boot the computer, but no display problem in Windows 10. Perform a quick check to fix RAM issues.

First clear the RAM. Wipe transmission preventing dust, dirt or corrosion. Next, remove the RAM sticks from your computer. Insert RAM sticks one at a time to verify if any of them are causing the error.

If your device detects problems with a particular RAM stick, you should fix it. Additionally, check the conditions of the RAM slots. Try different RAM sticks in different slots to identify faulty components that might be causing the problem.

4. Disconnect External Peripherals

External peripherals connected to your computer can also cause a blank screen. To fix this problem, you can disconnect and reconnect the devices.

To safely remove devices, first turn off your computer by long pressing the power button. Then you can remove the mouse, scanner, printer and other external devices on your computer. Next, turn on your computer.

Try connecting the devices one by one to determine which one is causing the problem. Then, replace the failed peripherals.

5. Troubleshooting Beep Code

Your computer has a specific beep code that sounds when there is a hardware failure on startup. Due to the uniqueness of this beep, you can easily identify the cause of a computer problem from the beeps.

To do this, first restart or turn on your computer. Next, pay attention to the sound the computer produces. Note the number of beeps and the length of the sound. Then use the motherboard manual to resolve the cause of the sound. Alternatively, consult an expert to better understand the meaning of the different beeps.

6. Reset Your Computer’s BIOS

If you have tampered with the BIOS or installed a beta version, it may cause a blank screen error on your monitor. Consider returning to default settings to reconfigure your BIOS settings. To start this process, turn off your computer.

To enter BIOS mode, turn on your computer and press the corresponding keys (usually F2 or F12 or Delete). Once your computer boots into the BIOS, find the option to reset the BIOS settings to factory defaults. After that, you will need to restart your computer. I hope this should fix the issue.

Fix No Screen

The above solutions should help fix computer turning on but no display issue in Windows 10. It is also recommended that you seek help from repair computers if you are not skilled with operations. Also, seek support from people or companies that have hardware components that you may need to test the functionality of the components.
