  1. Just checking, it seems like something is still wrong on this computer.

    just using a standard plain usb keyboard. All of a sudden this morning, when she was changing a plain ordinary mouse, the keyboard quit working. it works on another computer. the mouse works, while using the same usb port.

    in device manager, there is no entry for Keyboard. in devices and printers, way down at the bottom, a "usb multimedia" keyboard shows, but when I try to look at the drivers, there are several drivers, and I cannot delete, or disable any. Looking at the HID compliant consumer control device driver details, there are no drivers.

    Device Manager/Keyboard: shows keyboard. there are speed settings, but in the hardware tab, no name, manufacturer, location or device status.

    Just in case, with all of the problem we have had lately, I did some scans. the dss scan seems strange.

    Is it?

    Go into Control panel>Automatic update, click it & on the box that pop up, make sure automatic (recommended) is checked.

    The very first thing I did was that, but we always use the automatic. My problem on that computer was I cannot load the "standard keyboard" driver.

    But, I tried again. followed the trouble shooter link to download a new trouble shooter.

    This is the message I got:

    Issues found

    Potential Windows Update Database error detected 0x80070057


    Repair Windows Update Database Corruption


    Windows Update components must be repaired

    And this message:

    Microsoft Corporation

    When I tried to aces the file, I got this message.

    Windows cannot open the folder.

    Access to the Compressed (Zipped) folder:

    C:\Bettyh\AppData\local\elevated diagnostics\2560293460\2013033022.000\ is denied.

    As an aside, I was able to attaché a "wireless" keyboard & mouse combo, that worked (sorta).

    I tried two different ones from other computers. on both, the numlock pad didn't work. After several hours, I found one small item on a board I'd never heard of, but the suggestion was to look at the Ease of Access Center, and make sure that Mouse Keys were not checked to be on. Amazing, the number lock and number keys then worked.

    I don't know how that even got checked, but that was the first time (in 25 years of working with several PCs here at home, I'd seen that one).

    but after the "fix", plugging in a plain keyboard (the one that came with the computer), and nothing. AS long as the other's work, I don't care. (except that it bothers me that if a simple keyboard cannot be recognized. what else:

    I can't copy the Device Manager list, but, When the wireless combo is plugged in, The device manager icon for keyboards is visible (showing the kind), and the Mice and other pointing devices is also visible (with right driver).

    If I unplug the usb for the combo keyboard/mouse, both of those devices show, and in the Human Interface devices:
    2 HID Compliant consumer control devices
    1 HID Compliant Device
    1 Microsoft Hardware USB Keyboard
    1 Microsoft Hardware USB mouse

    by unplugging the Combo Device USB wireless:
    there are not HIDs (reasonable, seeing nothing is connected & no keyboard and no mouse
    by plugging a wired mouse, and nothing else:
    There is one USB Input Device in the Human Interface Devices section, and under Mice and other pointing devices 1 HIF Compliant mouse.

    if to the wired mouse, I also add a wired keyboard?
    If I unplug the usb for the combo keyboard/mouse, both of those devices show, and in the Human Interface devices:
    1 HID Compliant consumer control devices
    3 HID Compliant Device
    3 USB Input Device (but the keyboard doesn't work. Always try three separate USB wired keyboards that work on other computers.

    I don't know why.

    I tried to download the original keyboard driver from HP, but it did not help. the response was "cannot recognize device"

    If its a HP keyboard, go to their website. If not, go to the Keyboard manufacturers website. Other than that, its over my head. Good luck.

    Can you run a windows restore point , before this happen, If so this might correct your problem. Sound like one of your drivers were corrupted.
  10. I'm having the same problem with my razer black widow keyboard I've tried everything, what happened was I plugged it in and waited for the drivers to install once they installed I started using it but nothing was happening it had power running to it because it lit up but it didt detect it as a keyboard in the device manger in fact it has no idea what it is. I plugged in my original keyboard and the same thing happen I tried another keyboard and it happend again I think there is some sort of corruption but I have no idea I'm not taking computer science for my GCSEs so unless some one can swoop in and tell my what's going on I'm getting to the point where I might just wipe my pc and start all over but I would really like keep all my stuff. If you can please help
