    1. Please complete your specs (see mine for comparison) as this relates to hardware.
    2. Please post a screenshot of your Device Man. showing the problem
    use the Insert Image icon to the left of the video icon above your post

    What's the history?
    Have you recently upgraded to Win 10, or from 32 bits to 64 bits?
    Or were you running Win 10 ok and suddenly this happened?

    And which is your Win 10 version?
    (Win key + X, winver)

    Have you checked for Win 10 drivers on your manufacturer's site?

    Hi, I understand you've had Win 10 running on this PC for a long time; you've recently upgraded to the CU (from your screenshot).

    Have you had this problem since you upgraded to the CU?

    Again: Have you recently upgraded from 32 bits to 64 bits? (I guess your Win 7 was 32 bits with 4Gb RAM).

    Have you had 64 bit Win 10 running on this PC before?

    Again: 2. Please post a screenshot of your Device Man. showing the problem

    I guess this is a somewhat older laptop. (Ref. to mobile in your screenshot).
    It looks as if the model is Qosmio G50- is that correct?

    To complete your specs, a freeware prog. called Speccy is very handy.

    There are 64 bit Win 7 drivers, but none for Win 8.
    I was wondering about a BIOS update.. a few find that necessary to run later Windows editions for which their PC was not designed. One is listed for G55, not G50.

    As for your particular driver (whatever that may be- I've not seen your Device Manager or the device you're concerned about yet) - here's what I suggest you try:

    Download and run DriverMax (free for 2 drivers / day).
    Do a scan with that and see if it offers anything.
    I have used it 2 or 3 times successfully when in difficulty. (We would never normally recommend such tools for routine use).

    Note: In running a late edition of Windows on an older laptop you run a risk of thermal management not being properly implemented. I found I could not run one older laptop in Safe Mode in Win 8- it got hot and cut out. It came with Vista.

    CU is the commonly used abbreviation for the Creator's update- to save typing.
    As you know, periodically MS produces major builds- this is the current one.
    I'm assuming this problem arose after you upgraded to the CU as the timescale fits.

    Was your OS 64 bit before this? Or if you prefer, has it been 64 bit for some months? OR have you changed from 32 to 64 in the last couple of weeks? (Complete reinstall).

    As per previous: try Drivermax.

    Sorry, missed that before. So it's upgrading to the CU that's caused this.

    Two approaches:
    1. Update your BIOS (if you can find an update).
    (You can research how on your manufacturer's site)
    2. Try Drivermax

    Excellent- you're in luck.

    I'd have a look to see if there's a BIOS update anyway.
