sound card does not work correctly after Windows update

My sound card has been disabled when I install an automatic update for windows. There was an extra audio driver in Device Manager 'bluetooth AV audio' and audio peripheral anoither like this. After installation there is no sound coming out if my sound card was on the list of Device Manager. I followed several steps through windows help and support to solve the problem since seeing him on my laptop for mute also did not work. After you resolve the problem with the use of MICROSOFT FIX IT, it was fixed but this isn't the same quality that I get. Its volume is less eventhough volume: 100. The sound card that was originally installed on my laptop is "Conexant High definition SmartAudio HD2. Is there something more I need to do in order for me to get the same quality of sounds I have before installation?

Moreover, the light of my keyboard for caps lock shift and scrolling also failed after installation. I reformat my laptop after the incident, so I can get a good in the new system, but it does not solve the problem.

I also need to update my sound card for my HP laptop? Please help me.

Thank you!

  • Satellite P850 almost nothing works correctly after Windows update 8.1.

    Model: Toshiba Satellite P 850 part number: PSPKFV-00H002AR

    Machine is purchased in UAE (United Arab Emirates) UNITED with Windows 8 installed at the factory. Doesn't have a 3d screen. Doesn't have the capacity of Blu ray.

    I have the following problems: most of the stuff does not work properly after that I updated to Windows 8.1 Although I followed the manual of Toshiba.

    Some of the function Fn keys do not work.

    Eco button does not work (even if it does not work in Windows 8 also)

    Accelerator drive HARD does not work. says "caching works correctly", but when I go into the history of the use it has not been used since the day wherever I've updated to 8.1 Windows

    There is NO driver for the built in LAN card (manufacturer Realtek)

    The following solution is possible: uninstall all the drivers/utilities Toshiba and registry clean (with backup of course)

    Go to download Toshiba Driver and select the 64-bit Windows 8 operating system (I guess that's for computers with pre installed Win 8.1 at the factory?)

    Download any supplied drivers and see if everything works.

    (I always download my drivers on Toshiba EU website (no question of machine is bought from UNITED Arab Emirates) because I don't see any difference in the files and Toshiba MEA Middle East and Asia Web site is slow and does not work most of the time.)

    Also is there a manual with good order with installing the drivers? I guess that's something like Chipset driver > driver for Toshiba system > Toshiba flash cards Manager > then all the Toshiba Utilities > drivers for LAN, WLAN, sound, video, fingerprint reader?

    And one last question made Office Toshiba assist include the last HARD disk Accelerator utility? If not, where can I download the latest version of work for my model/brand computer laptop that works with Windows 8.1?

    null

    > Some of the function Fn keys do not work.

    To get all the keys FN works, installation of all Windows 8.1 tools is very important.
    Tools such as: * System Toshiba Toshiba function key utility, utility Support Flash Cards, driver *.
    You must look for each driver in the Windows 8.1 update 8.1 Windows 64 bit box

    > Eco button does not work (even if it does not work in Windows 8 also)
    You need to update/install the Eco Utility for Windows 8.1 update

    > Drive HARD Accelerator is not work says of "caching works correctly", but when I go into the history of the use it has not been used since the day where I've updated to 8.1 Windows

    Have you installed the utilities of the accelerometer and HDD Protection Utility for Windows 8.1 64bits?
    Where n t, the mentioned tools are located in the area of 64-bit Windows 8.1

    > There is NO driver for the built in LAN card (manufacturer Realtek)
    It's the same local network as for Windows 8

    Hello

    First do a hard reset.

    Please go through this Hotfix from Microsoft for the error you are getting.

    Please uninstall & update audio driver & BIOS after checking, you have such version specified in the site pilot here on the website of the HP product . Reboot after that. Do the troubleshooting in the Microsoft Fix document.

    When you're done, shut down the laptop.

    Disconnect the power adapter and remove the battery.  Press and hold the Power button for 30 seconds.  Reinsert the battery and plug in the AC adapter.

    Robinet tap away at the key ESC that you start the computer to launch the Start Menu, and then select F10 to open the BIOS menu.  Press F5 to load the default values (sometimes it's F9, but the menu below indicates the correct key), use the arrow keys to select 'Yes' and press ENTER.  Press F10 to save the setting and still use the arrow keys to select 'Yes' and press on enter.

    Check if its working

  • HP Pavilion dv8210us sound card does not work.

    Computer p/n ET831UA #ABA came with WIN XP Home Edition.  Designed for Windows XP, Windows Vista Capable label States.  I formatted the hard drive and loaded Windows Vista Business 64-bit.  I downloaded and installed all the drivers that have been recommended by HP, but my sound and Audio does not work.  Doesn't my mass storage controller or my PCI Modem.  All were working with WIN XP.  Need help on how to do all this work.

    Hello:

    Mass storage controller needs this driver...

    http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?sp4ts.oid=1847704&spf_p.tpst=swdMain&spf_p.prp_swdMain=wsrp-navigationalState%3Didx%253D%257CswItem%253Dob_70996_1%257CswEnvOID%253D2103%257CitemLocale%253D%257CswLang%253D%257Cmode%253D%257Caction%253DdriverDocument&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken

    But it's the only, you will be able to work as there are no 64-bit drivers for the audio or modem.

    While the processor may be 64-bit capable, some other material is not.

    Not to mention that your laptop can take up to 2 GB of memory, a 64-bit operating system will work worse than a 32 bit OS with only 2 GB of memory.

    64-bit operating systems require more memory and disk space to run the 32-bit operating system only.

    Not double, but more.

    My recommendation if you can install Vista 32 bit would be that you can use the drivers on your laptop support and the driver page.

  • A Satellite Pro 6100 graphics card does not work correctly

    Hello!

    I have a Satellite Pro 6100 (PS610E - 02c 60-GR) 1.7 Ghz, 256 MB, 40 GB, 15XT and a Geforce4 420 Go (32 MB) graphic card. Until yesterday it was working properly. Now, there are colors on the screen and there was a blue screen a few times, which says something about my graphics card (it disappeared from fast read).
    I uninstalled the old driver and reinstalled twice. Nothing has changed. Also I tried with an external monitor, but there wasn't any change, too.

    Now my questions:
    1. is it possible to change the graphics card (in particular, can I do it alone without a technician)?
    2. How can I do this, is there some tutorials, especially for my laptop?
    3. an another Geforce4, but for example a Geforce4 440 Go with 64 MB of RAM would fit in my notebook?

    I thank very you much in advance!
    Lukas

    Hi Lukas

    The led flashes as it provides a microcode error!
    This is especially if the malfunction of hardware has been detected.
    I presume that the replacement of the graphics card is the reason!

    As in previous discussions suggested the replacement of the graphics card is NOT possible. You don't believe!
    Looks like that the BIOS cannot handle this new graphics chip.

  • Windows does not start normally after Windows Update

    My computer does not seem to start more. Whenever it starts, it makes to the 'Starting Windows' screen, and then my screen goes black. My primary monitor does not receive a response, but my second monitor stays on until the computer restarts again. This happened last night after that my computer shuts down for the first time in a few weeks to install windows updates from July. I had updated windows to try to fix something with iTunes, which might have something to do with my problem. My computer was not showing any other kind of problem before that.

    Here are some other details:

    * I use Windows 7 Home Premium (Microsoft Windows Version 6.1.7601)

    * Windows does not load with normal settings but will load in safe mode.

    * System Restore never works in the system recovery (a non specifiederror occurred during system restore.) ((0x800700b7))  and sometimes says it works when I do it in safemode, but solves nothing. Yes, I tried using different restore points.

    * I think that my roots of the problem in the fact that I tried to restore my phone, but the computer could not install the drivers correctly.

    * Startup Repair does not detect it.

    Attempt to sfc/scannow in command prompt returns two different answers: "there is a system repair pending whice requires the restart ends.» Restart Windows and run sfc. "during the attempt to system recovery and" Windows Resource Protection found corrupt files and managed to fix their. " Details are provided in convertible bonds. Journal windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log"in Safe Mode with command prompt.

    I apologize if my description is a bit vague, but I need some urgent help with my computer. I tried all the solutions I've come across, but the same problem persists.

  • computer does not work properly after the update, because the screen is black.

    Advice please! :-(

    After an update there about 2 months, my computer has never worked properly after that I turned it back. My windows start page is longer there. My screen is black. The words are only in white and fluorescent yellow...
