Acer monitor SA230 causes bleeps randomly as if powered off.

My desktop will bleep (the same sound it makes when you power off the monitor with computer on) randomly all night. It does not do it while CPU is used. I have adjusted system settings to no avail. Lots of settings, including the impossible to see buttons to the actual monitor on the back bottom right side of the monitor.  Sometimes when it does it the monitor is dark and in sleep. Sometimes the monitor is lit, which is strange because this is hours after it was used. I replaced the very old surge protector, no change. My next step is to replace the power supply to monitor to rule out it being bad...causing fluctuations maybe?? Advice please.

  • Do these beeps have a sequence?

    They are random and single. Never cyclical or repetitive like 2 beeps or 3 beeps. 
  • However, does the computer start normally? Can you access the uefi by pressing f2 or delete?

    It shuts down and starts perfectly fine. This happens when the computer is on and not used for a while. I don't know what uefi is. 
  • Can you record a video with the beeps? Also, try doing a power reset by disconnecting the computer from the socket and then pressing the power button for thirty seconds!

    Sounds to me like the computer is waking up and going back to sleep periodically. Try this as a test, mute the volume in Windows and see if the beeps go away, if they do it's a problem in Windows and not in the monitor itself.
