That smells like an intermittent connection problem to me - bad cable, loose connection, or worst case a bad connector on the video output or the monitor. Try reseating the cables.

If the monitor and PC both support it, try connecting with a different kind of cable and see if the issue is resolved. That is, if you're running a DVI cable and both sides can use HDMI, try HDMI.

That sound is used for any device detected or disconnected. Such as a display. I've had it when I accidentally unplugged a display.
