His Dell Inspiron 1420, microphone and camera integrated into the laptop does not work after installing Windows 7 Professional

No sound from my Dell Inspiron 1420 and the microphone and built-in laptop camera do not work after installing Windows 7 Professional 64-bit. My laptop has Windows 7 Vista 32 - bit family premium. My laptop is 64-bit capable and after going through the Upgrade Advisor, I installed Windows 7 64-bit. I can hear sounds when I use a headset plugged into the line-in Jack, but not through the speakers built into the laptop. I already tried new drivers from the Dell website, but I could not find.

Any help will be much appreciated. Thank you.

As it is has no drivers 64 bit Windows 7 on Dell Web site, your best chance is to install the 64-bit versions of Vista (if they exist) in compatibility mode, viz:

Right click on the Vista driver, then select Properties > Compatibility tab. Now choose to run the program in Vista compatibility mode and then apply > OK. Right click on the file and select run as administrator to install it.

After you download the drivers of the camera, the camera become operative (YES!), but later worked for me, a built-in microphone was out of use.

  • My antivirus does not work after uninstalling windows 10 and return to windows 7

    I have upgraded to windows 10, but has had a few problems in general, especially with my keyboard, the printer, chromium and the office so I decided to go back to windows 7, but since kapersky does not work on my computer. I have full protection, but it will not work. I tried to restore my computer, but there is nothing before the upgrade to windows 10. I tried to restore to a previous version kapersky, but there aren't any. I can't uninstall it because it says it has been removed, even if it is still in the same place, I can't go back because he said that I have already. I tried running as administrator and in compatibility mode, but still does not work. When I try to run as administrator it says I don't have permission to access the item, but he isn't blocked or something. I don't know what else to do. Any ideas?

    You will probably never get Windows 7 running again, until you perform a new installation of Windows 7.

    I recommend a factory restore.  There is a hidden on your hard drive partition (assuming you have the original OEM hard drive) that has a copy exactly what was on your computer when you first started it.

    Tell us the brand and model and we will send you instructions on how to perform this.

    First of ALL, download your saved data.  Factory restore erases everything.

  • Internet and the sound does not work after uninstalling programs, System Restore also not work.

    I noticed that my computer felt a bit slow so I uninstalled a few programs that I knew were not very helpful so I restarted my laptop, and then the network and the sound does not work.

    Most often when a device does not work, it is because the driver is damaged. Re-install a new copy should help

  • Thunderbird does not work after installing Win 10 and the mobile profile of Win 7

    I've installed Tbird 38.3.0 on a new Dell computer with Windows 10 on this (8 GB of RAM, 1 TB harddrive). I then followed these steps to put my old profile from the old computer to Windows 7:
    1. copied my profile on the Windows 7 computer on an external drive.
    2 installed Tbird on the new computer Windows 10 38.3.0, but has nothing to do with it.
    3. following the instructions on the site of Thunderbird on the displacement of a profile:

      a) Use the Profile Manager to create a new profile on the Win 10 computer.
      b) Copy the profile from the external drive to the new profile folder
      c) Use Profile Manger to tell Tbird to open the new profile
    

    4. start Tbird.

    I see my files with email in them, but there are problems:
    1. None of the Tbird dialog boxes open when I choose a command in the menu bar (including the new Message).
    2. I can't get Tbird to display the contents of a folder in the Home tab. There is only the accounts and the advanced features of the Inbox, display in the right pane, next to the folder tree. The only way to see the contents of a folder is right-click and choose open in a new tab.
    3. when I click or double-click on a folder, the contents of the file does not replace the previous folder. TBird on the Windows 7 computer, clicking a folder displays the contents of the new folder.
    4. sometimes when I Alt + Tab of Tbird, then Alt + Tab, moving the cursor of the mouse on the messages in the Inbox tab causes the message object, Date,... to disappear, leaving blank lines.

    I tried to uninstall Tbird and reinstall it, but this does not solve the problem.
    I tried to reboot Windows 10 but that does not solve the problem.
    I don't seem to be able to download email and preview in the messages pane, but I can't open it in a separate window.

    A lot of people seems to be able to run Tbird on Win10, so it should work. Any ideas on why it does not work and what I can do about it?

    Thank you very much in advance!

    Hello

    Maybe you didn't install the driver for the microphone? Therefore, you will need to install the driver for the webcam, because the microphone is a part of it. You can get it here:

    After that, it should be possible to use the internal mic.
