Is f.lux crashing windows 10?



  • Anyone having problems? Nvidia graphics card, HMDI out.

    My system just goes black screen and then reboots to BIOS. No errors, nothing. Just black.

    Could f.lux be causing this?

    OR is it that Windows 10 is just really unstable? And has nothing to do with f.lux?



  • Open "Windows + Pause/Break" (Computer, right click > Properties). Advanced > "Startup and Recovery" settings. Here, uncheck "Automatically Restart".

    If you do not get a blue screen when this happens, then, well, I'm not sure I could help. When you restart, does windows tell you it recovered from a blue screen? It's a small window that says "check for solutions", and close.



  • Thanks for the reply.

    No, windows doesn't tell me there was a problem. And no check for solutions box.

    The screen just goes black. The I get sent back to the BIOS.

    I'm gonna try running it a few days without f.lux to test it. Although this morning, when I turned on my PC, I exited f.lux and it locked up a few minutes later. Maybe I'll uninstall f.lux and test it.

    I really like f.lux so I hope that's not the problem.

    Also maybe I should that memory.dmp file - maybe something in there?



  • Yeah, also check Event Viewer (sort by date).

    Just so you're aware, that's not the BIOS. It's the Power-On Self Test (the "POST"). The BIOS is something that you have to go into by pressing a special key like Del or F2 during the POST.

    So, what is happening can simply be described by saying that your computer is just suddenly restarting by itself.



  • Yes I have been getting a similar problem with only my HDMI out on a 3 display setup (two DVI and one HDMI), as well as random display driver resets when F.lux activates. The HDMI screen will go blank (no reboot), and I have to manually reset my display driver or reboot.

    I'm running Win10 and have a GTX 780.

    How frustrating. For you and other posters experiencing similar, the most useful information is to know your version of Windows, hardware type (like laptop, desktop, brand and model), GPU, and driver versions.



  • Desktop, Win 10 final, GTX 780, 355.60 drivers.



  • f.lux crashes Win10. It worked fine for my until Windows 8.1 then started crashing with 10. Installed it on the Surface 3 Pro, and that started crashing. I hated to part with it but I removed it from both and haven't had problems since.
    For what it's worth, I doubt that it's hardware. It's something specific to 10. Too bad.



  • Thanks for your nice post. The method that I followed to deal Windows 10 crashing is to use a tool-Windows Boot Genius. This tool can help me boot Windows computer again from any conditions. Like Windows black/blue screen of death, Windows freezing and so on. Maybe you can have a try. Wish it is helpful to you.



  • I think it is more a system issue. i have the same issue on my game pc.



  • @lorna I can confirm that f.lux is crashing Win10.

    My specs:
    Windows 10 (April 2018 update for obvious reasons)
    AMD FX6330 CPU
    Geforce 1050Ti (latest drivers)
    16GB DDR3
    Asroack 890GX mobo

    The screen simply freezes when I leave my computer on, it rarely lasts more than a day and I get home and the screen is frozen. No BSOD, no kernel dump, nothing. Complete halt.

    After I reboot I check event log, and there is NOTHING before the time of the crash. Windows does no the exact time of the crash though, as it keep an internal log of when it was last running.

    I have disabled f.lux and now for over a week not a single crash. This is after trying lots of other advice like turning off various power saving options etc.

    I have now uninstalled f.lux and recommend other people do the same.

    F.lux is causing blackscreen. We know the computer is on because we can hear the notifications but there is nothing on the screen. When i finally got the display back on(it's a hit-and-miss), i did online diagnostics test from the Dell website... I also did systems recovery diagnosis tests and they were all fine. It passed all the tests for Windows and hardware.
    (Have been using f.lux for 3 years now on my Lenovo Yoga500 laptop and one year on this Dell AIO desktop unit.)
    I uninstalled f.lux because it is the only suspect app that i installed which is related to the display.
    It solved my problem.

    There used to be some displays that would turn off when the blue channel went dim, but we haven't seen these in several years. Are you able to upgrade video drivers on the machine?



  • Same problem here. Crashing while playing CSGO, and recently in normal situations on Windows. After MONTHS trying to figure out what's the problem, I disabled f.lux and all went well.

    My pc: Windows 8.1, GTX 760, NVIDIA driver: 430.86.

    A week ago I bought a new graphic card believing it was the problem... A bit late :(

    Usually crashing Windows takes a video driver.

    Since we are not doing anything new I would try downgrading the nvidia driver to see if it helps?
