  • Windows 7 Ultimate, computer laptop Acer Aspire E15 built into the camera problem.

    I have a strange problem.

    I am running

    The laptop model is

    and first of all, as you can see - Acer only provides drivers for this model of laptop for windows 8, which is crazy because for ex I am running windows 7 on it or what do I do if I want to downgrade to windows XP, how to get drivers for my laptop?

    So my web cam driver was automatically installed with windows, BUT there is a problem.

    My camera only works with Skype and Firefox/Chrome.

    Skype recognizes it normally:

    but no other software can find and use the camera.

    webcam7 even after choosing the webcam as a source gives just a black screen:

    In addition to this, the windows software standard that normally comes with the windows called Camera - does not exist.

    The camera appears under devices.

    I tried to uninstall the driver. Install a new one. I tried everything I could find online, and nothing seems to work.

    It's almost a new laptop and it's crazy that I can't use such a common feature as the webcam.

    I'll send the same message to the customer of the Acers and see what is going, they say, but I reached a wall and do not know which can then do?

    TNX for taking the time to read this and any effort to help in the future :)

    Hello

    Please provide a detailed description of the issue with the screen shots.

    I certainly understand the inconvenience caused to you. However, I appreciate really all your efforts towards the resolution of the problem.

    In order to understand the issue more clearly, I'll ask you to provide me with the following information.

    1. You did it all hardware or software change on the computer?

    There could be a possibility that this issue would have occurred due to the damaged in the system device drivers.

    I want to provide you with the information that most Acer computers are preinstalled webcam application supplied by the manufacturer with the device. Uninstall and reinstall this application has helped many users of Acer for this problem to be solved.

    I suggest you follow the procedure recommended in the article given below for that matter Acer support.

  • I have an Acer Aspire One Netbook. (No DVD player). From the start on the hard drive, I get a black screen with a blinking cursor.

    I have an Acer Aspire One Netbook.  (No DVD player).  From the start on the hard drive, I get a black screen with a blinking cursor.  The cursor does not type.  For me, maybe I need to reinstall windows 7 and startup tasks are corrupt.  I have my product key genuine for the computer, but no way to get to windows.  How to restore windows on a netbook that won't start?

    original title: Netbook Windows 7 problem

    New computers coming often pre-installed with Windows 7 have what is called a recovery partition. This is used to reinstall an operating system in the case of a system failure. To access it, you need to start when you start your computer by pressing a function key. This can be either F1, F2, F9, F10, F11, F12 key DEL or tab. See the manual that came with your PC for instructions on how to reinstall Windows.

    If your recovery partition is not available or damaged, you must contact the manufacturer of your computer, and request that a defined recovery disk you can use to reinstall Windows 7. They could practice a small shipping and handling.

    Borrow a 32 bit Genuine Windows 7 friends DVD disc if you know someone who has one.

    Make an image of the DVD, you can use a program like ISO Recorder to do.
    http://alexfeinman.com/

    If you don't have a Windows 7 DVD to borrow, try to upload a picture:

    32 bit
    http://MSFT-DNL.digitalrivercontent.NET/msvista/pub/X15-65732/X15-65732.ISO

    You change the content of the. ISO file and delete the ei.cfg file. After having edited burn it to a blank DVD disc or put it on a USB key. Startup, it will reveal all editions of Windows 7, select the Starter edition. More information in the following article on how to change the file ei.cfg

    Select your country

    Click Next, call the number listed

    Once activation is complete, enjoy yourself, make a backup of your installation of Windows 7 Starter please? You will need to do this an external hard drive, but its worth it. Because if your installation is messed up, all you have to do is to restore from a backup.

On a hunch, instead uncheck one of them, I thought I'd see what would happen to let update all 3. It took a while, but, long story short, stopped the happy Vangogh and everything seems fine.

That's some 50 years ago, when "Transistors" were the most recent thing and the best around because the slices of bread, I kept my hand in all these years now, I generally pick up or buy laptops more elders or trays of office and repair install them a decent OS used XP but now finally agreed win 7 and use more.  Once started properly I sell them to local poor people in my area for what I have in them, and sometimes even give one to someone in need.  Just my way hopefully help someone at school and maybe have a better chance in life.

    The right click button does not work on the mouse pad, as well as a usb mouse. I used Acer to factory restore disks to restore it to out of box state. Same question. If you use the control panel to switch the buttons then the only thing that happens is the cursor move no click at all.  Also after a period of rental time computer warm up suddenly the cursor works, but even the left click will not work it will highlight the icon but not allow you to click on it. I wonder is the only solution to replace the motherboard as it seems to be a worse problem of heat.  Any help would be greatly appreciated.  And before I forget, Yes, I replaced the drivers a couple of both clean install so

    Looks like you did everything I thought and much more. He makes it sound like a problem with the hardware at this stage and would require the replacement of the motherboard. Looks like that the southbridge is not working properly.
