Acer Aspire its problems after Win 7 Pro and the new installed HARD drive

I have an acer aspire 8735 laptop g-6502 which has recently undergone a WD 500 GB drive HARD failure. I replaced that with a 7200 RPM Hitachi 1 TB drive and given that I don't have a Win 7 original used a disk Win 7 Pro with an extra friend.

Windows 7 Pro and HARD disk installation went smooth. But now when I plug an HDMI cable to watch through my Marantz receiver, comes from the video, but I have to do manually the Marantz the default audio device for sound. When I unplug the HDMI, I must return to the parameters of sound and unenable Marantz and re - activate the Realtek audio.

Before the drive died HARD, happen all perfectly when you plug the HDMI cable in and the fact to disconnect without any fiddling around with settings.

I also have a few other questions:
1. the touch volume control next to the numeric keypad does not control the volume more
2. the keyboard key used to have a setting to display it. You can use two fingers on a tablet to drag the image to the screen bigger and smaller.

I looked the site of Acer and also used my drive Application and drivers to reinstall everything that looked related to these issues. When first, I installed Win 7 Pro I let Windows find the appropriate drivers. It worked for some things but not others.

Any ideas? I have a few scratches on my face and my forehead in frustration pain making me beat me here. Funny, but true, so all ideas are appreciated!

Here's my screen design Mgr impression - there's an 'unknown' device IDK how to understand what it is.

  • Inspiron 13-5323 does not start after the new installed hard drive

    Fall of my Inspiron and Geek Squad said she needed a new hard drive.  I installed a new identical to the former myself blue WD.  When activated, it immediately passes to "Phoenix Securecore Tiano Setup.  Pre-launch tests indicate that the new hard drive works fine.  I tried to start in safe mode UEFI and in the boot Legacy mode, but no boot.  I get a message "Not found operating system".  It is my understanding that this computer has an operating system embedded on the motherboard.  I previously had it improved Windows 8.1 to 10.  When I tried to boot mode safe mode using F8, I had the same operating system not found message.  The F2 and F4 keys on commissioning do nothing different, either.  Am I missing a step in the window settings of Phoenix?  Suggestions while in Phoenix window bringing me could happen to start the system would be appreciated.

    In fact you have reloaded the operating system?  If not, the new drive is empty - it's why you see the message you see.

    You will need all the recovery media, as you did when you received the system - or, if you do not prepare a set, you will need to call Dell to buy a flash drive with the media today.  The alternative is to download Windows 10 TH2, of the same version (standard, pro) that has been installed and activated previously.  You can then reload the operating system.

    Here is the link for the driver sata for your model:

    It could happen to your model, it's why W7 cannot find the hard drive.

    You will need to download and install this free program.

    After installing 7 - Zip, right-click on the Sata driver you downloaded and select 7 - zip option in the list.

    Select extract to: I leave extract the name of the file and extract the exe file in a folder of driver.

    Once you have the file, open it and copy the contents of the folder on a drive portable usb flash without the src folder.

  • Can I run After Effects with 2.4 GHZ Quad Core i7 Processor, 16 GB of RAM and a new SSD hard drive?

    I have a 2011 Mac Book Pro with 8 GB of RAM and The RAM Preview plays in 10 second Incraments. I want to pull out my hair! I don't have the sum of $ to buy a new computer. If I switch to 16 GB of RAM and get a new drive SSD will work After Effects, or I lose my $$. Please help, I have a very important project. It is about 12 minutes long and I need to add a lot of sequelae to complete my project

    First of all, you have optimized your system: Optimizing after effects of performance - Support Adobe

    Second, it looks like you are fairly new to AE and that your workflow is not very effective. Here's the deal. After effects is not an editing application, it is a graphics and compositing designed app to create shots or short sequences. In addition, I would say that more than 90% of my AE projects are less than 10 seconds, because I created shots (with handles - extra images) I'll change in the body or some other NLE. Some of these comps second 10 have a hundred layers or more. If I had to do 12 minutes into a movie I would fuck the cut first in Premiere Pro to understand what was the best way to tell the story, then each shot than necessary effects would become a separate AE comp. At the very least each scene must be a model. In most of the stories that are told, as a film, a scene are only a minute or two. The average is probably less than 6 seconds. I can't imagine putting together 12 minutes in a single model AE, not because I couldn't, but because I would probably change the "timing" of some of the cuts, edit audio or make some other change before I made and changes in the middle of a project of 12 minutes would be a nightmare.

    Here's how a work on almost all editing projects.

    • First installation in a NLE such as Premiere Pro until the story is logical
    • Put the shots in AE requiring animation or effects
    • Inside AE, I first make a test pencil to check the overview and animation timings with the Panel of the model to 50% or even 25%, and automatic resolution scheduled to ensure that the timing is ok
    • Effects are added and critical frames are checked 100% for color and everything else but I rarely to ram preview several frames because I'm already happy with the calendar
    • The model is sent to the SOUL (Media Encoder) or sometimes the cue to render to render in a production format appropriate (usually 10-bit or better, often a sequence of images)
    • If the model is sent to the SOUL I continue to work on the next shot until I finished all the effects work
    • The effects of rendering images are reduced in the NLE to replace shots in the rough cut and editing is polite
    • The project is then added to the hearing for the final mix
    • The final color ranking is made - usually in the category of speed or resolution
    • The final product is made to a production for archiving format and a format of distribution (usually h.264 mp4)

    There are a lot of bounce back, but it's the most effective way to work on any project. Have you noticed that an overview of full resolution RAM full length does not at any time?

    If installation requires only a few short shots or sequences to AE, I will occasionally use Dynamic Link, but most of the time all the effects work is made. It just makes it much more efficient.

    I hope this helps.

  • I have a DATE TIME / CMOS / BIOS with my Acer Aspire 5742Z problem


    Newbie here...

    I have a strange problem with my Acer Aspire 5742Z (UK), which I think may be the BIOS or CMOS area...


    Guard reset BIOS default time (00: 00:00 on 01/01/2009)... OR... a time '' close '' to what it is supposed to be...


    Removed the main battery and then replaced the CMOS battery twice (in the case of a failure)

    Main battery insert it again.

    The clocks of the BIOS (using F2) countless times, but there's rarely / or is correct.


    During startup in Windows 7, it almost always does not show the same date and time that I entered the BIOS.

    For example, if I go home at 21:35 on August 28, 2014 using F2, when I boot on Windows, the date and time may say August 23, 2014 at 3:25 pm ish...


    If I turn it off and turn off and then turn on, restart the time in BIOS is correct... to 21:43 29/08/2014 (that I have record for good measure).

    If I continue, Windows reads now August 23 at 15:32


    So, then I change the time of Windows Date to Friday, August 29, 2014 21:48.

    JUST FYI: the PARAMETERS of ZONE SCHEDULE are checked and no changes: (UTC), Dublin, Edinburgh, Lisbon, London

    PANEL, LANGUAGE AND REGION, English in the United Kingdom, short time 21:48, short Date: 29/08/2014

    GEOGRAPHICAL area: United Kingdom

    now, everything seems correct.

    TURN OFF AGAIN and wait a few minutes.

    YOU turn it back ON, and then press F2 that (this time) shows the BIOS default date and time in 2009

    If I continue in windows without changing the BIOS date and time dafault, Windows now displays as 23:02 31/12/2008


    That's all.

    I would really appreciate help fixing this problem that makes me nuts!

    Thanks in advance!

    ...   Just in case anyone reads this...

    I just updated my BIOS for the next issue, and the problem has.

    I guess that maybe the BIOS got corrupted!

    I used the simple approach and no short layout has been involved.  I deliberately did not go for the latest BIOS just in case where he brought new questions and confused the situation.


  • I have an OEM Win 10 Pro and want to downgrade to Win 7 pro, but don't have Win 7 Pro iso or disc

    I have an OEM Win 10 Pro and want to downgrade to Win 7 pro, but do not have Win 7 Pro iso or disc. The seller tells me that MS will provide Win 7 Pro to achieve, but my Windows 10 Pro product key does not work on the download page.

    Thank you


    If Pro 10 Windows was preinstalled on your computer, see how in-depth instructions downgrade:

    How Downgrade Windows preinstalled 10 for Windows 7/8.1

    As mentioned in the article, it is your responsibility to facilitate access to Windows 7 Professional reinstall media. He may be borrowing retail upgrade or full version of media or OEM System Builder.

    You can use the following utility to download the ISO of Windows 7 Professional:

    Microsoft Windows and Office ISO download tool -

    Instructions for activation phone activation use after decommissioning in detail article I linked at the start. No need to buy Windows 7 Professional.

    Instead of replace, you might want to consider dual booting:

    How to: Dual Boot Windows 7 or Windows 8 with Windows installed 10 first

    If what you bought is an OEM System Builder Windows 10 Pro license, then you can indeed buy Windows 7 Professional.

    Because Windows 7 is in limited stock because Microsoft ended sales in October 2013, this created demand due to its rarity. This means the retail boxed copies request a bonus, while the OEM System Builder copies remain affordable.

    Full version (retail):

    -Includes the rights of transfer to another computer.

    -Does not require a qualifying earlier version of Windows.


    Upgrade version (detail):

    -Includes the rights of transfer to another computer.

    -require a qualifying earlier version of Windows.

    -Expensive, but less expensive full version

    OEM System Builder version:

    The OEM of Windows 7 versions are identical to the versions commercial full license with the following exception:

    -OEM versions don't offer any free direct support from Microsoft technical support Microsoft

    -OEM Licenses are tied to the computer first you install and activate it on

    -OEM versions allow all hardware upgrades except for an upgrade to a different model motherboard

    -OEM versions does not move directly from an older Windows operating system

    There is nothing wrong to use it too, especially that all future versions of Windows will be full versions.

    You can find software OEM System Builder of dozens of online merchants. The current price for OEM Windows 7 Professional Newegg, for example, is $ 140. When I checked a few minutes ago, Amazon offered packages OEM Windows 7 Professional from several vendors at prices ranging from $ 101 to $ 150. When I checked earlier, a package specifically designed for reconditioned PCs cost only $ 50 for a 64-bit copy.

    There is no technical limitation to prevent you from using OEM software on your computer, although this software only works for a clean install, not an upgrade. In the past, Microsoft has been remarkably inconsistent in his advice to clients on the question of whether this practice is allowed. (See "is allowed to use Windows OEM on your own PC? Don't ask Microsoft. »)

    Please note that Windows 7 Release Candidate is a preliminary version of Windows and should not have has been used as a release candidate.

    However, the requirements for the media upgrade is that you have an operating system already eligible such as Windows XP or Vista installed to use it. Since the Windows 7 end user license agreement.

    15 UPDATES. To use upgrade software, you must first be licensed for the software that is eligible for the upgrade. After the upgrade, this agreement takes the place of the agreement for the software that you upgraded. After upgrade, you can no longer use the software that you upgraded.

    So, if you are always denied, you will just have to reinstall Windows XP or Vista and let it do the verification of eligibility.

    There are no Windows 7 drivers for your model, something that you should have checked before the upgrade.

    There are Vista drivers on the Acer site which may operate, but don't hold your breath...

    I could format the HARD drive and then install or what I have to do something with the Bios.

    Of course, you can install Win XP on this laptop.

    Can I ask you if you have already created a Toshiba Recovery DVD?
    I guess you laptop supports the recovery of HARD drive and no drives have been provided with this device.
    Before to format the HARD drive, you must create a recovery DVD using the Toshiba Recovery Disk Creator.

    Furthermore, I believe that you are not able to install XP because the SATA driver were not included in your Win XP operating system.
    Well, on some laptops you can disable the SATA AHCI in the BIOS and could spend in compatible mode. This would install the Win XP without a SATA driver.
    But this option is not available on all models of laptops. You need to check this first.

    Finally, I must say that this topic has been discussed a lot of time here in the forum. Maybe not specifically in the forum of Qosmio X but in the other forum and the SATA installation procedure is the same on all laptops.
