No internet, no sound after recovery

Recently, I replaced a hard drive failed on my Toshiba laptop.  Once the recovery process is finished I had no noise or Internet.
Windows cannot verify the digital signature for the following:
Atheros AR8132 PCI - E Fast Ethernet Controller (NDISB6.20)
Conexant High Definition SmartAudio Pebble
Intel(r) High Definition Audio HDMI
Mobile Intel (r) 4 Series Express Chipset Family
Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC
I used the recovery DVD from Toshiba to return to 'out of box' then say why do you have this occur and how to fix it?

Hi koko,.

This problem can be caused if the audio drivers and network are absent or damaged. I suggest you to download the latest audio drivers and network the computer manufacturer's Web site and check if it helps.

See: /Update-a-driver-for-hardware-that-isn't-working-properly http://Windows.microsoft.com/en-us/Windows-7

  • 3110CT no sound after installing XP Pro

    I am a novice when it comes to laptops, so here's the problem: my 3110 ct no sound after installing XP Pro. Had no noise when I bought it with another operating system, the report says no audio devices installed.

    Does this mean that I have to make a chip for laptop or a driver, I need & where can I find the driver or the part for this.

    Help, please.

    Usually, if the audio driver is not installed you will get no sound, but also a yellow exclamation point must appear in Device Manager.

    If the sound card chip is damage, I imagine that you will not be able to see the yellow exclamation point belonging to the sound card in Device Manager.

    You bought this Portege as a second hand unit. Am I wrong?
    So maybe the sound card is faulty.

    The computer uses an ES1978 ESS (Maestro-2E) and sound chip ES1918.
    Check if you can find an audio driver XP in internet.

  • Cannot download programs and basic games after recovery.

    All of a sudden we cannot download programs of basic games, after recovery we cannot not even down load dap download eccellerator!

    can help us, that's happened is that during the last 5 days.

    Hi Eric,.

    Chances are, something happened during the recovery process that prevents you from downloading something on the internet. One of the most common reasons for this is that the security settings are set too high. See the link below to learn how to change the security settings.

    http://Windows.Microsoft.com/en-us/Windows-Vista/change-Internet-Explorer-security-settings

    Another reason that you might not be able to download whatever it is could be the settings you have enabled in your anti-virus program, if you are running one. If you are, try to disable the program while you download those

    T is not easy to tell exactly what is happening on this virtual path.
    When your Qosmio freezes you have to like what's next? To restart Windows OS or what?
    Is everything OK again when your Qosmio restarts?

    You know that's not easy to understand exactly what is happening. Is there an error message?

    Maybe you should reinstall OS and test functionality with the 'settings '.

  • Partition lost after recovery - Satellite L30

    I had two partitions on my HD (Satellite L30-114).

    I used the Toshiba recovery Cd to restore windows back to my laptop. The CD has not offered me a full mode or an Expert as written here http://support.toshiba-tro.de/kb0/FAQ350072001GR01.htm he has just recovered without any input on my side!

    After recovery, Windows does not see my second partition. I used the disk management utility, and it is said there are 17 GB of disk unassigned space (this is my second Partition!).

    Can and how can I restore it?

    TX a lot!

    Hello

    It seems that the L30 comes with a new version of the recovery cd.
    I think that the recovery procedure is a bit different than the old with 2 different recovery modes (standard and expert)

    I know a little new recovery procedure because a friend of mine bought a new Satellite with this recovery CD. He asked me for the installation of the laptop and we checked.

    It seems that you must press the setting button after the language selection.
    If you n t use the button setting for the configuration if the recovery procedure will be remove and erase everything on the HARD drive. I think you didn't configure the settings and therefore all the partitions have been deleted.

    Unfortunately I think that there is not much to do. You the partition has been deleted and it of not possible to bring back the lost data.

  • Windows does not start after recovery

    Hey, satellite 1800 started son to have more and more slow to the point where it took close to an hour to boot in Windows. It got to the stage where it seemed that recovery from the CD was the only road - so we did. Everything had to look successful from the point of view of recovery but the installer of Windows XP displays "Please wait...". "with the normal activity of the disc looking for 20-30 seconds and then hangs - no disk activity, the mouse is not responding. I went through the recovery in "expert" mode and don't see any problems with the recovery process. Issues related to the:
    1 no matter who else seen elsewhere?
    2. what else can I do diagnosis-wise?
    3 which, basically, the recovery process not / (fact he re - format partitions, could it have left a virus?)
    4. I'm better h/w or s/w diags?

    Bitshifter

    Hi Bitshifter,

    topic of your question 3:
    The recovery process replaces the whole HARD drive or even a partition with an image created by Toshiba. This image contains an operating system, drivers, and a few basic programs. All other data (including viruses) in this partition will be deleted.

    question 4:
    I don't know the cause of your problem, but I think it's a hardware problem, because after recovery, there may be incorrect or missing software.

    Sorry I can't give you more information.
    Good luck!

    No sound after updating Windows 10.

    Installed HP Support Assistant, which came with a video to try a headphone jack with Windows 7, so no joy there.

    Although this suggests that the failure of the scan, produce a result: Driver (1)

    Hello:

    I recommend that you try the audio driver IDT W8.1 support page for your laptop.

    This works in most cases.

    This package contains the driver that allows Audio IDT high definition (HD) in the notebook models that are running a supported operating system.

    File name: sp58406.exe

    If the W8.1 driver does not have the noise at work, try this...

    Go to Device Manager and click to expand the category of audio, video and game controllers device.

    1. click on the Audio CODEC of IDT high definition in Device Manager.

    2. click on the driver tab.

    3. click on Update Driver...

    4-> select Browse my computer for driver software.

    5. Select-> Let pick me from a list of drivers for devices on my computer.

    6. Select Audio device high definition (not IDT high def...)  "This is important). and click Next.

    Warning message is displayed, but the answer Yes.

    7 Windows has updated your driver software.

    8 restart the PC

    Key is step 6

  • Re: No sound after install Vista - Tecra M7

    I improved my Tecra M7 to Vista (and then upgraded to Vista SP1) but the computer is no longer plays sounds (no music, no sound system - nothing)

    I installed the latest Realtek HD driver, I have the latest version of the Bios.

    Device Manager indicates that everything is working. "Speaker" icon tells me that his work (the green bar follows the beat of the music)

    The volume & button Mute works - I can't get the "speaker" modifying, turning to the top/bottom/inhibition icon. I tried the headphones in and out.

    I checked the bios if the sound card has been disabled it - but it seems that there is no possibility to change the settings of the sound card in the bios.

    Does anyone have an idea on what I'm doing wrong here?

    Maybe I can help you;

    I read on a sound problem after installation of Vista it happened if XP was preinstalled on your laptop and the mute box was accidentally activated.
