    Original title: RAM upgrade

    Hi again! I have another problem now. My computer is a netbook, EeePC1000, with 1.6 Ghz, 1 GB RAM and 160 GB hard. OS: Windows XP Home Edition. I tried the upgrade to you with a new memory KINGMAX-DDR2-PC5300-667 RAM. The problem is, my OS to recognize only 0.99 GB of the 2. What can I do? It's just a setting problem or other? Please help me! Thank you!

    Hello

    Your English is better than a lot of people I know and I'm English by English nationality!

    OK, from your description of the memory, it seems to be the correct sorting. I'm skeptical that a BIOS upgrade will help (I looked in the notes to upgrade the BIOS on the ASUS website), so let's check a few things before you consider as an option.

    First of all, what you do makes you think that Windows can see 1 GB? If this isn't it (or its equivalent)...

    • Hold down the Windows (between Ctrl and Alt) key and press Pause break
    • Examine what is listed in the computer: section

    .. .so please do the above and respond with the details.

    You say it's an EeePC1000 but is there something that comes after the 1000, for example H, HA, HD, HE or HG?

    Are you sure that the memory module you have purchased is actaully a module 2 GB instead of 1 GB module? Have you seen the actual label on the module (as opposed to its packaging)?

    When you start the PC, before Windows XP starts to load, you see anything by telling you how much memory is installed? It can not be displayed or may be displayed briefly, not blinking! If you do not see this indication can you enter the BIOS Setup and check from there? Unfortunately, the Asus site gives a manual with no information on the use of the BIOS. You need to look for a message from depression F key at boot time (usually F2 or Del but I saw others also). When you press this button, you should get in the pages of the BIOS settings. Look for the amount of memory installed. Exit BIOS without saving the changes, just in case you accidentally change a setting.

  • Windows XP prevents me from installing the new hardware as my Canon camera and memory card reader.

    original title: problem with new hardware

    last week, windows xp prevented me from installing new hardware, namely a canon digital camera and a memory card reader. Although the system recognizes the material into the machine, when you are looking for auto install it asks me for the service pack 3 cd, which I did not. I never had problems, install new hardware before. Any ideas why this happens?

    Hello

    · What is the service pack installed on the computer?

    · What is the model number of the canon camera?

    · What is the exact error message that you receive with error code if any?

    If you have installed service pack 3 on the computer then you can try the method and check them off below if it helps:

    Change the registry to point to the installation of Windows XP Service Pack 3 files

    Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs.

  • Satellite L650-14F - Windows 7 I need to install?

    Little help? If I install the 32-bit version of windows 7, all the RAM will be shown as windows xp 32-bit?

    Hey Korn,

    The amount of RAM you have installed right now?

    Windows 7 32 bit will also detect the same memory Windows XP 32-bit, but way General OS 32-bit can handle just 3.2 GB so if you have 4 GB or more RAM installed, you cannot use the entire capacity.

    But you are right, Windows 7 32-bit and 32-bit Windows XP detects the same RAM.

  • How to get the amount of memory installed?

    (It's under the Windows operating system)

    I have do a comparative analysis program for the performance statistics for some complex calculations based on the hardware.

    What is the best way to get the amount of RAM installed programmatically?

    How do I know if the OS is 32 or 64 bit?

    Thank you!

    Well, it does not resemble the Memstats VI returns the memory installed. It returns a number, but I can't match the amount of memory installed on my system. The GetCurrentPlatform seems to return only the name of the OS, not whether 32-bit or 64-bit. I see nothing in the App-> target list containing this information. At least to 8.2. Did not check in 2009.

    Define "better". Best in speed? Better compatibility on multiple versions of the Windows operating system? Best in terms of access to this information without having to delve too in all sorts of types of data Windows and DLLs?

    Would you consider .NET stand for the 'best '. If so, the amount of RAM installed can be gained from easily using the Microsoft.VisualBasic.Devices.ComputerInfo class:

    To determine whether your OS is 32 - bit or 64 - bit are you trying to make a distinction between a 32 bit on a 64-bit CPU vs OS a 64 bits on 64-bit OS? I know that the WMI class can be used to obtain this information, so if you try to make this distinction, you could watch the Win32_ComputerSystem and Win32_Processor classes. For example, I think that what follows is what you would see:

    OS 64-bit on x64processor:
    Win32_ComputerSystem.systemType = pc x 64
    Win32_Processor.addresswidth = 64
    Win32_Processor.architecture = 9
    Win32_Processor.DataWidth = 64

    32 bit on x86processor OS:
    Win32_ComputerSystem.systemType = x 86 pc
    Win32_Processor.addresswidth = 32
    Win32_Processor.architecture = 0
    Win32_Processor.DataWidth = 32

    OS 32 bit on x64processor:
    Win32_ComputerSystem.systemType = x 86 pc
    Win32_Processor.addresswidth = 32
    Win32_Processor.architecture = 9
    Win32_Processor. DataWidth = 64

    I've attached an example on how to access the classes with .NET. Not pretty, but not too bad either.

  • Windows 7 Windows is low on memory

    Hi, I'm running A Dell Inspiron laptop. Pentium CPU at 2.20 Ghz with 3 GB of Ram. Operating system is Windows 7 Home premium 64-bit with service pack 1. These last two days I get the error warning "Windows is low on memory." I looked at the performance tab in the Task Manager and even with closed programs, memory was raised near 97%. I tried to change the page file size which I do not know if I did it with the correct parameters. I also tried to uninstall programs to free up space on the hard disk. I tried safe mode with network and memory in the corresponding mode was only 27% I am trying to register all relevant information. I always face the problem though. I can't afford to support. Can someone advise me please what to do to get more virtual memory? What steps to take? Any help would be greatly appreciated.

    That's a lot to support a good swap file. I suggest that you set to allow Windows to manage the size, especially if you do not know how else better to adjust.

    With a proper file error is rare. This may indicate a problem program consumes excessive RAM or malware problem.  I suggest that you look at the processes tab in the Task Manager first. Sort on the column of the memory.  What are the rare albums?

    Also, check your computer for malware.  In addition to your antivirus program I suggest you run these good free programs.

    Hi Konyga,

    If you already have a warning on the internal HARD disk before Windows starts I would recommend sharing it and backup all data as quickly as possible.

    Is your laptop still under warranty?
    If Yes, you can get a new HDD to an authorized service provider. It would be free because it s covered by the warranty. All you have to do is contact with an ASP.
