DM4-1140SA (Windows 8 Pro - 32-bit) hardware upgrades - that will give the most bang for my buck

Laptop specs: http://support.hp.com/us-en/document/c02550724

Which would improve the more noticeable performance for example change the HARD disc of the SDS, the 3GB DDR3 8 GB RAM DDR RAM upgrade? Could you give an indication of how much improvement I could hope with each of the suggested upgrades? Also, could you give some suggestions of what specifications technical I should look for spare parts.

In addition, suggestions of software to improve performance would be greatly appreciated?

Thank you very much. Yan

The Pro 840 is the one you want. You can't go wrong with a SATA III... even if the computer interface is SATA II, SATA III work as well as a SATA II will and will obviously better on a port SATA III. Here's the memory you want to... DDR3 SO - DIMM 1333 mhz PC3-10600 aka.

    How can I download an installation image for the s/w Windows 7 that I activated?

    Thanks for your help.

    For 5 years, Microsoft made it fairly easy for users of the Windows 7 operating system to get reinstall media. If you have lost your support disc or installation retail collection; either it has been damaged or defective; You can download a copy of the edition that you have licensed from a membership site called Digital River. More recently, Microsoft ended the availability to reinstall media that you can download as a. File ISO in Digital River, which is a digital reproduction of an optical disc.

    It was particularly convenient for people who could not easily get the manufacturer's recovery media, did not want to pay the fees required to get or preferred a clean configuration without the software packaged manufacturers or even a recovery partition does not work. It's easy to use, all you had to do was reinstall and reactivate using the product key located on the certificate of authenticity and download all the drivers on the manufacturers website.

    Given that this option is no longer available, what are your options? See the article for more details:

  • Impossible to install any program because not supported under Vista, but my PC is Windows 7 Pro 64-bit

    I try to install Rockwell Automation Studio 5000, but I get an error message saying "Studio 5000 is not supported on Windows Visa without Service Pack 1 or higher". However my PC is under Windows 7 Pro (64 bit) and Vista that is covered by the requirements of this program.

    Any ideas?

    What is the version number of Studio 5000 you have?

    You can try to install using the "compatibility mode".

    What is program compatibility?
    Program compatibility is a mode in Windows that allows you to run programs written
    for earlier versions of Windows. Most programs written for Windows Vista are also running Windows 7,
    but some older programs might run poorly or not at all.

  • Intermittent USB mouse freeze on Windows 7 Pro 64-bit. Tested with several mice that work fine on other computers.

    I am having a frustrating problem where my Wired Optical mouse appears to 'freeze' for 10 seconds on my machine Windows 7 Pro 64-bit. Meanwhile, everything else on the computer works fine, including the keyboard (connected through PS2). The mouse does not seem to lose power because down the red LED stays on. At the end of the freeze period, I hear the sound of Windows to disconnect USB, but there is no error or windows pop-up ads of any kind on the screen.

    Some more info about the configuration:

    * Core i7 950 processor
    * 12 GB of RAM
    * Radeon HD4950 video card (or almost)
    * The main SSD drive
    * 2 external powered USB drives, 1 powered MIDI keyboard, 1 USB dongle
    * Windows experience score 7.3

    I tried things that did not work:

    • Turn off all the power management, including the management of power supply for USB, USB hubs-> suspend to win power, etc.
    • Permutation of mouse. The problem came with three different mouse from different manufacturers.
    • Try the mouse on different computers of W7 Pro. Confirmed that the mice are not the problem.
    • Disconnected all other USB devices except the mouse. Problem persists.
    • Uninstalled all the drivers for the mouse and use MS default drivers.
    • Installed the software Microsoft mouse & keyboard center.
    • Installed the software from the manufacturer (ie. logitech) specific mouse driver.
    • Tried every USB port, the front and back, on my computer, including USB3 vs USB2.
    • Scanned for malware (using Malwarebytes)
    • Search for viruses (using Nod32)

    I must point out that NO other devices are having problems on this computer. My external hard drives all work perfectly. My printer when I plug it, works great, like my USB dongle. My MIDI keyboard never loses connection. Even when I have my phone connected Android, which normally creates a huge noise if I unplug it, never disconnects even for a second. It is therefore clearly a kind of mouse problem.

    The problem seems to occur regardless of what I do, although it seems MORE common if I use actually the mouse. If I'm just typing (as I am now) it seems not really to happen. On the other hand, sometimes hours go with no problem and other time it happens literally every few seconds.

    Remove the check to "improve the accuracy of the printer" logic. I had two computers windows 7 x 64 that gives me the same problem. When I tried a wireless mouse, the problem disappeared. they do not use the windows controls.

  • Reinstall Windows 7 Pro 64 bit after failure SSD

    The SSD in my HP laptop is not this weekend. He had installed on it when I bought Windows 7 Pro 64 bit. How can I reinstall the operating system, because I don't have the original OS installation key? Surely I don't have to buy a new OS. In fact, I plan on upgrading Windows 10 once that I get it upward and running.

    At the same time, I remember being able to call a technician at Microsoft, explain the situation and get a new key issued. Is it still possible?

    In addition, if CS5 is compatible with Win 10, must I first uninstall CS5 on my current computer before you install on the new machine, or can I just use my CS5 disk to install directly on the new PC with Win 10?

    Thank you

    Richard

    No need to uninstall CS 5 old machine. it is very very important to turn off activation in the menu helps to record the number of activations.

    All individual applications can be activated on 2 machines. Regarding the number of activations for more details, you can check with the help of Adobe once and get confirmation.

    Hmm, what about compatibility... cannot say it is completely compatible, but you can give a try. most of the cases, it works fine, but we cannot guarantee or say how it will work smoothly or can be installed on Windows 10 without any problem.

    If you face any problems with the installation disc, you can download at the bottom of the link:

  • HP Pavilion 15 lowered a score of 8.1 for Windows 64-bit for Windows 7 Pro 64 bit driver problem

    I just downgraded a HP Pavilion 15 Notebook, which was just recently bought with Windows 8.1 64-bit installed.

    The owners could not get with Windows 8, so they bought Windows 7 Pro 64 bit.

    After changing the option of Secure Boot UEFI BIOS, I installed windows 7 for them, installed the drivers from the site HP Web for this model of laptop, but there are a few drivers who will not not turn on.

    Product number is F8S59EA #ABU

    SYS ID card is 2163

    Intel processor Core I5-4200U @ 1.60 GHz

    8 GB memory

    BIOS Version F42 has been upgraded to F62

    But there is a PCI device in device without driver manager now, details of the error are:

    PCI DEVICE

    Hardware ID

    PCI\VEN_10EC & DEV_5227 & SUBSYS_2163103C & REV_01

    There is also another error of unknown device listed, the details are:

    The unknown device properties

    Hardware ID

    ACPI\HPQ6007

    I don't know if this is related to the first error message, but I thought I'd list them here anyway.

    In addition, try to install the software Cyberlink listed on page of drivers for this laptop, Cyberlink Director Photo software, the software Cyberlink PowerDVD and PowerDirector Cyberlink software all refuse to install.

    PowerDVD and PhotoDirector gave "Software can be installed in the machine allowed" error message and PowerDirector gave the error message "is not a valid HP drive, the installer stops now.

    If someone could please help in telling me that drivers are missing, (I enter all the machine ID in the box HP drivers, pilots said it remained for this machine, installed correctly, just these some problems) I would be most gratefull and the owners of laptops would be too!

    I don't know if this is related to the first error message, but I thought I'd list them here anyway.

    In addition, try to install the software Cyberlink listed on page of drivers for this laptop, Cyberlink Director Photo software, the software Cyberlink PowerDVD and PowerDirector Cyberlink software all refuse to install.

    PowerDVD and PhotoDirector gave "Software can be installed in the machine allowed" error message and PowerDirector gave the error message "is not a valid HP drive, the installer stops now.

    If someone could please help in telling me that drivers are missing, (I enter all the machine ID in the box HP drivers, pilots said it remained for this machine, installed correctly, just these some problems) I would be most gratefull and the owners of laptops would be too!

  • DownGrade Windows 8 Pro 64 bit on 4540 s HP Probook Windows 7 Pro 64-bit

    Hello

    can someone tell me the correct procedure to downgrade pre-installed 64-bit Windows 8 Pro that came on my laptop 4540 s newly purchased to Windows 7 Professional 64-bit? Machine itsself comes not with any media. I also read the key is now also integrated into the BIOS. As I intend to replace the 500 GB HDD with a SSD 250 GB, I would like to re - install windows 7 at the same time. I know that you can download the vanilla windows versions 7 of m6mobile.fr and others and then install but I wanted to know if there was a formal process for HP machines. It would be also good to know that the process of extraction of the COA, so I can activate Windows 7 installation completed.

    I am based in the United Kingdom (and an employee of HP)

    (it seems I'm not the only one having this problem - I guess this method works http://www.pcworld.com/article/2015107/downgrading-from-windows-8-to-7-what-you-need-to-know.html?pa... )

    but before could someone confirm that part "call microsoft" will be ok for me if I have no physical cost... also what can I do if I have not a pro windows 7 product key to enter during the installation of windows 7 - because obviously I intend to use the rights to downgrade to windows 8 pro key!).

    advice appreciated.

    Ad.

    Ok...

    so having figured out that I can downgrade sounding MS I took the lead and mounted my new SSD drive and installed Windows 7 Pro 64 bit. Everything is good. What I need now is some of the correct drivers to get me going.

    If someone could point me to the right for the following, I'd be grateful so I don't waste time to download everything. My version is HP Probook 4540 s C4Y79EA (i5-3210/4 GB RAM/15.6 inches) model British.

    Some of the choices pilot have several versions of pointers to good enjoyed.

    It is mainly in the field of the network drivers for the Wifi and fixed ports.

    Thank you.

    I determined what hardware is in this model.

    WIFI/Bluetooth - download drivers Ralink

    Ethernet card integrated - download the Realtek drivers.

    The rest should be pretty straigtforward...

    Cheers.
