desktop screen is blinking this message back and forth "you just plugged (unplugged) a device from the audio jack. When I move to another jack it says "no audio device is installed"
Check the Device Manager as it could just be a corrupted sound driver needs re-installing. Otherwise, it may be the audio card or on-board audio chip has blown up/burned out due to a power spike.
You will need to fit a new sound card if that's the case.
