“No Signal” message on Monitor
When switching on your CPU, you can get the message
“No Signal” displayed on your monitor, though the whole system is running. This issue might be due to several factors that you should check before drawing any conclusions:
- 1. The cable linking your CPU to your monitor might not be properly plugged or has been damaged. You should hence ensure that the connection between the two devices has been properly done and that the cable’s state is fine.
- 2. You might be facing a problem with your monitor if the CPU makes a single beep error sound when you switch on the system. You can check whether the problem comes from your monitor by testing it on another CPU. If you still have “No Signal” error displayed including the error beep, I would strongly suggest you to try to get your monitor fixed by a competent technician or to get a new monitor.
- 3. If you receive several error beeps when starting the computer, this might be linked to a graphic card dysfunction. You can refer to the motherboard notice or check that the connection has been properly set.
