The computer turns on but no display on monitor or keyboard
There could be several reasons for this problem and we will take a look at each of them one by one.
Why does my PC turn on but no display?
If your PC turns on and there is no light or display on your screen, there is a possibility of one of the following things:
- Your monitor is turned off. There could be trouble with the power, the electric connection or the cable that powers the monitor.
- Monitor dysfunction. There is some internal disorder or damage in your monitor’s hardware.
- There is a disconnection between your monitor and computer. This can be caused by a rusty cable connection or an impaired video port.
- One of the peripheral devices such as your printer, mouse, scanner or microphone is causing a disruption leading to a blank screen.
- The basic input output system managing the booting system of your computer is faulty.
- Your device is outdated and needs an update
Why does my monitor say no signal when I turn my computer on?
If your computer is turned on, fans moving, initial beep sounding, and your monitor still says ‘no signal’, it could mean a few things. The display signifies that your monitor is intact and functioning. There is, however, a lack of input signal from your processor which may be due to the following reasons:
- Your computer isn’t set to connect to the proper source
- The cable connecting your computer with monitor is loose, broken, rusty or improperly attached
- The port accepting the connecting cable is dysfunctional.
What do I do if my monitor isn’t displaying?
If your monitor is failing to display, try following these steps to correct any discrepancies:
- Ensure that your power supply is stable
- Reboot your computer. Check the connections (cords and cables) between your PC and monitor are intact and secure
- Check functioning of monitor. Connect your computer with another monitor to see if it works
- Unplug any peripheral devices
- Remove and reconnect your RAM
- Re-evaluate your input-output settings.
