    Hi

    Let's say THEORETICALLY: A while back I took notice about an odd behavior. In random intervals, hours in between, my screen goes white for a split-second. One time it even minimized a windows I had open.

    Is there any way to log this behavior? To find out - without brute-force - what the culprit is?
    I want to see what program called for this "screen-update" or whatever it actually is. (I have no clue. A handle?) Could I do that with Process Monitor, for example? That program shows many things. Is this one of them? I'd say no.
    I guess this question is more the guy that is kind of forensically observing his Operating System.

    How would you investigate such a thing on a basic level?


    :)

    I would start by ruling out monitor or graphic card issues.

    Make sure all your monitor connections are securely fastened. Then check the connection from the monitor to your PC. Then insure the monitor is securely plugged into your power source. If the power source is a surge protector setup, etc., plug the monitor directly into the wall outlet.

    If the problem persists, swap the monitor with another one.

    If the problem persists, open up device manager and verify both the monitor and the graphics card show with no warnings associated with them.

    If the problem persists, reinstall your graphics driver.

    Apart from hardware issues I meant.
    Hm... are there some handles that software can call or something like that?

    USA still the best. But barely.

    "What is BGInfo EXE?
    The genuine Bginfo.exe file is a software component of Sysinternals BGInfo by Microsoft. Bginfo.exe is an executable file that runs Sysinternals BGInfo, a tool that let users display system information on the desktop background. This is not a critical Windows component and should be removed if known to cause problems."

    Did you write that for the general public? ... I think I have to rephrase things...

    EDIT:
    I totally rephrased the OT. Please read again. :)
