    Not sure if this is where I need to post this at, but I have a HP All in One WINDOWS 10 COMPUTER.
    it has started doing something very strange. The screen will go black and it will start making a very loud sound like a foghorn and the only way to get it to stop is to unplug it. It doesn't do this often but it does it.
    What in the world could that be? It did this about 3 this morning and woke us up and it was unplugged.
    So far, the noise continues when you plug it back in. It will eventually come back on. Puzzled:confused::confused:

    When you say it an "All in One" computer, I take that to mean you're referring to a desktop and not a laptop, correct?

    Yes it's a desktop monitor with everything in it. I've never seen or heard anything like it. :eek:

    Hello Nola,

    If I am reading this correctly, the foghorn sound occurred while the system was unplugged at 3:00 A.M.? If true, I can only conjecture one situation that would generate a noise when the system has no power; which would be due to some type of a transmitter being near the speaker wires, where emanations (possibly from something like a cell phone????) build up in a feedback loop and are then dispersed through the system speakers.

    Good luck figuring this one out!

    Lol, no it is plugged in and on, usually playing music or just on. The screen will go black and the sounds begins. You cannot get it to stop until it is unplugged. Maybe 3-4-7 hours later, you can plug it back in and it'll conversation on and be fine for a week or so. Or plug it in and the noise is still there .

    No, the computer is on and usually playing music or just on. The screen goes black and the noise starts. The only way to get it to stop is to unplug it. If you plug it back up 5-6 hoesh later, it will either come on and work fine for a few weeks or month before it did it again. Or it will start making the noise again.

    I tried to start it in safe mode but with windows 10 the PC has to be on to go into safe mode. It won't come on to do the step. To you know if a way to do it like other Windows?

    Yes I know. I was asking for clarity, as she'd mentioned it had happened at 3am, but it was unplugged.

    Only thing I can think of is a power issue within the machine. Not sure about a foghorn though... maybe a fan going to fast?

    If you can provide a video that might help. If you have a product number and serial number I can have a quick look

    If a fan was going too fast and had something rubbing against it (like a wire), it's plausible the metal case is amplifying the sound. Hard to know for certain without opening the system.
