    Windows 10 slow startup, short black screen before Welcome screen


    Hi TenForums people,

    Firstly i'm sorry if i posted this to the wrong thread im just a junior member lol.

    So on to my problem...

    I'm having a much much slower startup time. And i mean really slow. I'm using Windows 10 Pro x64 build 10586.916 on a quadcore AMD processor with 8gbs of RAM and a 7200 rpm hard drive. Quite a new PC, only three months old.
    More than a week ago (June 1) i resetted this PC but keeping my files because of some other issue, so it's all working perfectly again.

    Quite.

    But now that i reinstalled some of my programs, i'm having some sort of sequence that always repeats and never changes at startup-
    1. BIOS screen
    2. Short monitor flickering
    3. Windows logo with a loading circle (6s)
    4. Flicker
    5. Windows logo with a loading circle but laggier (10s)
    6. Flicker
    7. Black screen with a responsive mouse cursor (7s)
    8. Loading circle on a grey screen(7s)
    9. Welcome screen (15s)

    Thats how it always goes when restarting, but with a clean start (shutdown-5mins-boot) #5 & #6 seems to be skipped.

    I believe this is caused by my graphics driver. When i checked the ntbtlog there were lots of entries of my processor, IGP drivers and other notable windows drivers (esp. dxgkrnl.sys) not being loaded. I have an attachment of the ntbtlog.

    ntbtlog.txt

    This week i've been uninstalling and reinstalling my graphics drivers for about 3-4 times but still no noticeable change. I've also seen the threads extremely similar to mine about this and used the temporary fixes but the issue keeps going back.

    Can someone tell me what's going on? I really need this PC and boot times are actually important to me.
    Really huge thanks for someone who answers.

    Hi, welcome to tenforums
    1. Your build
    I'm using Windows 10 Pro x64 build 10586.916
    2 major build upgrades have been released since that build (November 2015), one last year, and the current one.

    Could I ask - did your 3-month-old PC come with this build, or did you install it using an old DVD/iso/boot disk?Are you using the old build of choice or necessity?

    2. Could you clarify - slower than what?

    I'm having a much much slower startup time.
    Meanwhile you could try disabling Fast Startup as an experiment.

    Thanks.

    Symptoms you describ are generally caused by an outdated driver. Are all your drivers up to date ?

    I'm thinking that upgrading (and new drivers) could be a more straightforward approach than trying to use technical tools for boot time analysis.

    Let us know about any performance changes turning on and off fast start up and whether or not your drivers are up to date.

    In case that does not fix the slow boot there are additional options:

    1) Place you computer in clean boot to turn off all non-Microsoft services and start up items.
    How to perform a Clean Boot in Windows 10 - TechNet Articles - United States (English) - TechNet Wiki

    https://support.microsoft.com/en-us/...oot-in-windows
    This should give you the fastest boot times.
    If there is a noticeable difference in clean boot you can then work on isolating the service that is negatively impacting the boot.

    Also open administrative command prompt and run:
    1) sfc /scannow
    2) dism /online /cleanup -image /restorehealth
    3) chkdsk /scan
    Let us know the results of each scannow, restorehealth and chkdsk /scan

    Thanks.
    Hey dalchina huge thanks for the reply.

    1. I'm using 10586 cause it came with my PC,

    2. The boot times were much slower when i resetted and then reinstalled my programs.

    P.S. I'll try to disable fast startup first...I'm taking this lil PC back to my seller tomorrow btw.
    Thanks again.

    I think it's the drivers too. I'm still using the ATI drivers that came with my motherboard CD.

    I can't make sure that it's the drivers though, cause the first time i bought the PC i never had any boot problems and it's using the drivers from the mobo CD...

    I also tried updating it multiple times before posting on this site cause after updating i didn't seem to see changes...
    Thanks for the reply though

    Ok, let's look at this differently.
    1. You have a very old build. Again, could you explain why you are using an old build?

    Note that with current builds MS is continually updating their compatibility lists (see the multiple installs of one update which is continually updated - confusing new approach). Yours is a new PC - is it possible that because you are using an old Windows build you're not getting the latest drivers?

    2. Please confirm that Windows Update fails on your PC.

    Please post a screenshot of your Update History like this:

    3. Please confirm you have done nothing to disable Windows update, and have not set your connection as 'metered'.

    @zinou - wouldn't it be wise to find out why it's not even updating before trying to analyse boot problems- further, why diagnose an old build like this?

    Far better to do an upgrade one way or another- and that may well resolve everything.

    That an old build is in use may even be linked to a slow boot.

    I'm trying to reach a point where either Windows update will work, or, more simply, get a manual upgrade done.

    I would prefer that, having checked the disk, the OP simply downloads an iso, creates a bootable Win 10 medium, and upgrades the Windows build.
