    Hello, I'm running Windows 7 on a Compaq Presario CQ56.

    Revently I've been having trouble with the multiple display settings changing on their own on my laptop. I've never had an external monitor hooked into my laptop, but for the past week or so my laptop will give me a notification that an external monitor has been plugged in, then it will disable though nothing has been change. I havan't downloaded anything recently besides windows updates and I have no idea what could be causing this.

    Any help with this would be great; It's incredibly frustrating.

    Hello & Welcome to Tech guy Forum.

    Please run this forum's sys info utility & post the results.

    Which of these 17?

    When did the problem begin? Sometimes the exact date is important.

    What changed? A hardware [ printer or other peripheral ] or software install or removal; an update to W7; update to a program [ anti malware or other program ]?
    Which updates to W7 correspond to the problem onset? Look particularly for driver updates [ graphics / video or chipset in particular ].

    Run HP's diags, particularly the hard disk drive.

    Run Prime95 diags for the ram.

    Boot to safe mode & test. It probably won't occur because in safe mode, only basic drivers are used; probably not one that enables dual monitor use.

    start > search
    Left click in the results area
    the system config utility will open
    Create a screen shot, using W7's snipping tool.
    Return here > "go advanced" > manage attachments
    browse; upload; close; submit

    A screen shot of that to which you refer would be helpful.
