Testing possibly damaged RAM before installing it

I had a disaster with my old G4 desktop recently. My dog relieved himself onto a USB hub (not sure how long ago) but at some point while computing there was a system error warning me that my hub was drawing too much current and would now be shut down. The computer went into fits and started crashing frequently and finally quit. I discarded the hub and removed a PCI card that had four USB inputs on it. I got a replacement motherboard/CPU combo and it was either bad or something left inside the computer case fried the replacement components. Over time I was able to bring back the hard drives with an entire replacement computer. The damaged computer had 2GB of RAM on it but I'm afraid to try it in the replacement G4, and don't want to discard it unless I really have to.
Is there a way to test the old RAM BEFORE moving it over or should I just write it off? Possibly if I test it it might look OK for a while and then fry my "new" G4 at some point in the future!

Look at this link: *Testing RAM* @ http://guides.macrumors.com/Testing_RAM Then download & use Memtest & Ramber.
Do you have an Apple Hardware Test disc? Running the Apple Hardware Test in Loop Mode is an excellent troubleshooting step for finding intermittent hardware problems. It is especially useful when troubleshooting intermittent kernel panics. If Loop Mode is supported by the version of the Apple Hardware Test you are using, you run the Extended Test in Loop Mode by pressing Control-L before starting the test. Looping On should appear in the right window. Then click the Extended Test button.The test will run continuously until a problem is found. If a problem is found, the test will cease to loop, indicating the problem it found. If the test fails, be sure to write down the exact message associated with the failure.In some cases, RAM problems did not show up until nearly 40 loops, so give it a good run.

  • Execution of Coded UI scripts with least possible test execution time in Windows7 Operating system using Visual Studio Test Agent 2010 without VS2010 installed

    Hi All,
    We are trying to execute coded UI scripts without Visual Studio installed. We are using “Visual Studio Test Agent 2010” for executing coded UI scripts without VS2010 in Windows 7, it is working fine. Also we verified executing the same script with VS2010
    Premium, it works fine as well.
    Here the challenge we are facing is with the Test execution time.
    When we run the coded UI script with IE11-Windows 7 OS-Visual Studio 2010 Premium it takes
    3min 36sec to complete the execution whereas with IE11-Windows 7 OS-Visual Studio Test Agent 2010  it takes
    6min 40sec for the same script to execute (which is almost double the time it takes while executing using VS2010).
    My question is what may be the reason for this difference? and how we can reduce the test execution time when running from Test Agent 2010?
    Kindly let us know what is the best practice to execute the coded UI scripts with least test execution time in Windows 7 Operating system using Visual Studio Test Agent 2010 without VS2010
    installed.
    Looking forward for your positive response.
    Thanks in advance..!!

    Tina-Shi, Thanks for the information.
    As you mentioned, we tried to execute the coded UI test using Mstest.exe in command on VS2010 Premium and checked on the execution
    time, there was a slight difference.
    Please find below execution time.
    Using Mstest.exe in command on VS2010 Premium/Win7 – 3.47 minutes
    Using VS2010 Premium/Win7 – 3.53 minutes
    Using Test Agent/Win7 – 7.3 minutes
    Also, I closed all the other processes in Task manager before starting up the execution.
    Still , I am facing the same Issue. Could you please suggest any other way to reduce the scripting time of coded UI script execution
    through Test agent 2010.
    Looking forward for your earliest response.

  • Can we 'test' a plugin or extension "BEFORE" upgrading FF? I have a password toolbar from Nortons that I love. Can I test the next FF version before installing?

    Every time I up the FF version, I learn my nortons toolbar is not compatible. Then I have to UNinstall and resort to last version. Some time later, I learn the nortons toolbar will now work in the newest FF so I upgrade. When the new FF rev comes out, I go through it again. Is there a way to test toolbars before installing the newest FF?

    Norton usually has an update available each new version of Firefox the same day (or next) that Mozilla releases a new version. Running a Norton Live Update after the new version of Firefox is installed usually solves Norton Toolbar compatibility issues.

  • I have seen so much response about the Mountain Lion update slowing down computers.  I am updating from Mac OS x 10.6.8.  What can I do to ensure the upgrade will go fine?  Do I unplug my external hard drive before installing, or keep it plugged in?

    I have seen so much response about the Mountain Lion update slowing down computers.  I am updating from Mac OS x 10.6.8.  What can I do to ensure the upgrade will go fine?  Do I unplug my external hard drive before installing, or keep it plugged in?
    Also, I have the 08 version of iWork. Will this cause problems for the update?  Can I update this AFTER I update the processor?

    Welcome to Apple Support Communities
    There's no reason to think that Mountain Lion will slow down your Mac. Just make a backup of your data before upgrading with Time Machine > http://support.apple.com/kb/HT1427
    Also, check that your apps are compatible > http://www.roaringapps.com Upgrade them to a compatible version or delete them before upgrading.
    The external drive won't make the OS X Mountain Lion installer fail, but it's better to unplug it during the upgrade.
    iWork '08 is compatible with Mountain Lion. iWork '09 includes OS X Mountain Lion features and can be purchased at the Mac App Store.
    To upgrade to OS X Mountain Lion, I recommend at least 4 GB of RAM. You can check how much memory you have in Apple menu > About this Mac

  • Do I need to uninstall the Photoshop CS6 trial before installing Design & Web Premium?

    I'm studying game design and my school provides a full license for Photoshop CS6. Before they provide the license they require you to install the software and use the 30 day trial, so that's what I did - I just installed the Photoshop CS6 standalone version (the full thing, not Elements). Now that my trial period has expired I've been given the license, but it seems it's for the whole Creative Suite 6 Design & Web Premium, not just Photoshop.
    Should I uninstall Photoshop standalone before installing the whole Design & Web Premium suite? Or will it be okay if I go through the installation of the suite and just deselect Photoshop from the installation options? Is there any difference between the version that's installed on its own and the version that comes with the Design Premium suite? Will it affect any functionality in terms of transferring stuff between applications?
    I'm running Windows 7.
    Thanks in advance.

    Only if you want to or need the space... versions are independent... some people have several versions installed for testing different capabilities

  • Do I need to upgrade my graphics card before installing CS6?.....currently

    Do I need to upgrade my graphics card before installing CS6.....currently have Nvidia quadro FX1800 with CS5.......what card would be recommendation for a one man operation that would like to take advantage of the mercury playback engine?

    I agree with the recommendations for the GTX 660+. I also second John's advice to completely uninstall the existing Quadro drivers before you swap cards.
    And that Quadro FX 1800 never worked with MPE GPU acceleration even in CS5 because although it has CUDA capability, it has only 768MB total VRAM on the card. MPE GPU acceleration requires a minimum of 765MB of free, unused VRAM - but a 768MB card leaves only 749MB of free, unused RAM because the Windows GUI itself consumes nearly 20MB of VRAM. And even if the FX 1800 had 1GB of VRAM, it would be sluggish-performing by current standards because the FX 1800 is really based on a downclocked GeForce 9600 GT (with only 64 CUDA cores) with a narrower memory bus width (192 bits instead of 256 bits, both DDR3).

  • How do you test any SAP objects before a transport to the production server

    How do you test any SAP objects before a transport to the production server?

    Hi Rama Krishna,
       The actual process is develop the object in development system and unit test there with the available data.
      Then move it to Quality server where the data will be the actual replica of production and where the integration testing and ened to end testing happens and also the user acceptance testing  happens there.
    and once everything is found fine there then it is moved to production system.
    Award points if this is helpful.

    Dear  MAC-Friends.
    PLEASE HELP ME.
    I am extremely afraid to do something wrong - what will be a failure so I loose all the photos I had in my iphoto library before installing the Mountain Lion.
    I have just installed the MOUNTAIN-LION and now I can´t use my Iphoto-programme without answering the following question:
    Choose another Library ?  ( But I only want the choose the photos which one was in the old iPhoto-Library and not the other photos on the MAC-computer ? ).
    and the other possibility is:
    Create a new Libray ! Which iPhoto-library  ?
    And why create a new and to risq to loose the old photos.
    PLEASE HELP ME.
    Kind regards  FINN GRABOWSKI

    Ok. Let me first ask you, do you have any backups of your files - for example, do you use Time Machine or any other backup system?
    Next, quit iPhoto. In the Finder, go to your Pictures folder. Is there a file there called iPhoto.Library? How large is it? (If it doesn't show the size, click once on it, click cmd-I to see the information). If it's a healthy size (ie, several GB), then that should be your library, and you can double-click it to launch iPhoto. (The application will remember where your library is next time, you can just launch iPhoto normally).
    If that's not the right file, check your Trash. Is there anything in there?

  • Install 10.4.11 before installing 10.5?

    I just got Leopard, and haven't had a chance to install it yet. Now that they've released 10.4.11, I'm wondering if I should upgrade to it before installing Leopard. I would prefer not to install it, just because OS upgrades always make me a bit nervous, so I would like to do as few as possible. My system seems to be working fine right now, and I would hate for something to go wrong before installing Leopard. But then again, I wasn't sure if installing Leopard on top of 10.4.11 would be "safer" than installing it on 10.4.10.
    What do you guys think?

    I would install Leopard over 10.4.10. I think it's safer, but in either case backup everything before even thinking about either.

  • GPO to uninstall Flash before installing 10.1.53.64

    When pushing out a software installation for the new install_flash_player_10_active_x.msi, it leaves previous versions installed even though Adobe's Flash test site says that the latest version is installed and in use. However, I'm sure that it is probably "best practice" to push out a script to uninstall all previous versions of Flash [i.e. uninstall_flash_player.exe -uninstall] before installing the latest version (10.1.53.64).
    Is anyone using a GPO to push out a script to uninstall the previous versions of Flash before running the .MSI or .EXE to install the latest version (10.1.53.64)?We have several Flash versions out there, so attempting to Upgrade from an old GPO package AD isn't thorough enough.
    I've tried running the uninstall_flash_player.exe -uninstall file (as a .VBS) with a precedence of 1 before the software installation GPO (as startup scripts), but it produces mixed results, so I'm not sure that this is the best method.
    So, two questions here:
    1) Does anyone forsee any real issue leaving previous versions installed (i.e. not uninstalling before installing new)?
    2) Otherwise, how is everyone handling uninstalling and reinstalling via GPO? Better suggestions on how to and in what order to push out the uninstall and install processes?
    Thanks much for your suggestions!

    I am not using GPO, but to the best of my knowledge, the installer should automatically uninstall all previous FP versions.  See the install.log file (if that is produced using GPO).
    However, sometimes the installer is unable to remove all components of old FP versions, e.g. if the users have web browsers running during the installation.  This may get fixed during the next reboot, but often it is not.

  • What is the proper way to format a new HD as GUID before installing Leopard

    Before installing Leopard on my new WD RE3 HD I went into Leopar disk utilities and chose PARTITION and then under advanced I chose GUID and let it do its thing. Now when the disks display on boot (I have both Leopard & Snow Leopard dosks availale) when I hold down the OPTION key the Leopard disk shows as "Leopard" but the new Snow Leopard disk displays as "EFI Boot" and I have been told it's because it was not formatted as a GUID disk. Would installing and booting up with Snow Leopard even be possible on a non GUID disk? The Snow Leopard drive is designated as the boot drive and it boots up just fine with no error messages... only when I do a selective boot do I see it as "EFI Boot disk"

    Sorry to disappoint, but...
    I have a MacBook Pro and I have partitioned my internal hard disk to have both Leopard and Snow Leopard. When I restart the computer holding the option key, it shows both Leopard and Snow Leopard. Then I choose which one I want.
    Now, I installed the new Disk Warrior 4.2 on my Leopard partition and recreated the directories for the Snow Leopard partition. Then when I restart holding the option key, it shows Leopard and EFI boot.
    This leads me to conclude that DW 4.2 somehow hosed something in the disk. Being the coward that I am I had backed up my Snow Leopard partition. Put it back and it shows, Leopard and Snow Leopard as expected.

  • Please install Visual Studio 2005 before install Acrobat 9 Plugin Wizard

    Hi,
    I have Visual C++ 2005 Express Edition installed on my computer. I keep get error message said "Please install Visual Studio 2005 before install Acrobat 9 Plugin Wizard" when I installed Visual Studio App Wizard  Acro9PIWizInstaller.msi.
    Any idea?
    Thanks,

    Lol
    Do you take me as a joker ?
    *Of course I have contacted the micorsoft support first !*
    *They ask me to try to install the .net framework 3.5, to see if the setup wasn't define as XP compatible.*
    *Then they don't have answer yet and asked me to contact Toshiba support (funny no ?)*
    Also If you look at the microsoft support forum the only installation pbm with Visual Studio with Vista is toshiba laptop satelitte related
    Ok now, as it's my job, here is what I think :
    Maybe the laptop was first setup with XP and maybe Tshiba reseler did install Vista on it as a migration !
    First case
    So to be absolutly sure it wasn't the case I did a format of my HDD and reinstalled vista from the Toshiba Crash and recovery CD
    Second case
    The problem remain, so it is possible that this Recovery CD and/or any other Toshiba product create this problem !!!!
    Note that the C# or J# express just work fine, it's only the Visual Studio 2008 tem suite and pro

  • A Word of Warning Before Installing Login/Keychain Update:

    After I installed the above update and rebooted my computer, it wouldn't load the menubar, dock, or anything except the desktop. So I had to force reboot. After that, OSX would only open into OSX setup assistant, as if my previous account and all information never existed, even though it was still on the hard drive! So I restored my previous system from a Time Machine backup and now it's mostly back in working order. So make sure your stuff is thoroughly backed up before installing the update!

    I'm not sure if this is any different in the UK but in the U.S., Apple handles ALL iPhone repairs and exchanges under warranty.
    If you purchased your iPhone more than 14 days ago, you need to contact AppleCare or make an appointment at an Apple Store if there is one nearby.
    You can return an iPhone within 14 days after the purchase date for a refund, but if the packaging is opened, there is a restocking fee. If there is a warranty claim, you contact AppleCare or make an appointment at an Apple Store if there is one nearby to have your iPhone inspected and tested for repair or replacement under warranty.

  • Do I need to install CS3 on Windows 7 64 bit before installing CS5 Upgrade?

    I am replacing a graphic designer's Windows Vista laptop with a Dell Precision T5500 desktop.  Do I need to uninstall CS3 from the laptop and decommission the serial number?  Then do I need to install CS3 on the new desktop before installing the CS5 upgrade?  I was told I needed to decommission the installation, but I don't remember having to do that with other installations.  Thanks in advance!

    You should definetly deactivate any software before uninstalling. But you don't have to install CS3 in order to install CS5. Just have the serial number handy for verification. That said, depending upon the user's needs, you might want to leave CS3 available.

  • Remote printer is recognized but message says can't find printer?  It worked great before installing OSX Maverick

    Remote printer is recognized but message says can't find printer?  It worked great before installing OSX Maverick?

    Thank you for your response.
    Unfortunately I have already rebooted the router and that did not fix the problem. The weird thing is that the computer is connected to the network, it just won't connect to my computer. I have printed the network configuration page to confirm this, and it says the wireless signal is strong. 
    I have not changed anything at all recently in terms of routers, networks, etc. The printer stopped working completely randomly.
    Is there a part in the printer that like emits a signal which computers, phones, etc are supposed to detect? I don't know enough about the mechanics to really theorize about what is wrong, but it seems like that is the only thing that stopped working. 
    Do you have any other suggestions?
