Test With Another Monitor

Experiencing a “No Signal” message on your monitor can be frustrating. One effective way to troubleshoot this issue is to test with another monitor. This method helps you determine if the problem lies with your computer or your monitor.

Borrow A Monitor

If you have access to another monitor, borrow it for testing. This could be from a friend, family member, or even a spare one you have at home. Connect this borrowed monitor to your PC. Ensure all cables are securely connected. Turn on both the PC and the borrowed monitor. If the borrowed monitor displays correctly, your original monitor might be faulty.

Check For Display

Once you have connected the borrowed monitor, check for a display. Look for any signs of life such as lights or logos. If the borrowed monitor shows a display, your original monitor is likely the issue. If there is still no signal, the problem might be with your PC.

Common issues to check include:

• Loose cables
• Faulty ports
• Graphics card issues

If you need further assistance, consider seeking help from a professional.

Check Power Supply

A common issue causing no signal to the monitor is the power supply. Ensuring your power supply is functioning correctly can help diagnose the problem. Follow these steps to verify and test the power supply.

Verify Power Connection

First, ensure all power cables are securely connected. Check the power cable from the monitor to the wall outlet. Confirm the power cable from the PSU (Power Supply Unit) to the motherboard is connected.

• Check the wall outlet for power.
• Verify the monitor’s power cord is plugged in.
• Ensure the PSU power cable is connected to the motherboard.

If the connections are loose, the monitor might not receive power. Use a different power outlet to rule out faulty wall sockets.

Test Psu Functionality

Testing the PSU ensures it delivers power correctly. Follow these steps to test the PSU:

1. Turn off the PC and unplug the power cable.
2. Open the PC case to access the PSU.
3. Use a PSU tester to check the PSU’s output.
4. Connect the tester to the PSU and turn it on.
5. Observe the tester’s readings for any issues.

If you don’t have a PSU tester, use the paper clip method:

• Unplug the PSU from the motherboard.
• Bend a paper clip into a U-shape.
• Insert one end of the clip into the green wire’s pin on the 24-pin connector.
• Insert the other end into any black wire’s pin.
• Plug in the PSU and switch it on.
• If the PSU fan spins, the PSU is likely functional.

If the PSU fails these tests, consider replacing it. A functional PSU is essential for your PC’s performance.
