    My computer just started having a problem after I installed some new RAM. I
    have 2 gigs of Corsiair PC2-6400 RAM, and I just installed 2 gigs of Kingston
    PC2-6400 RAM. Now when my screen saver starts, it crash's my computer.
    Also, now when I open my windows mail, I get the following error. Header
    reads "Winmail.exe-entry point not found". Information block reads "the
    procedure entry point destroywin could not be located in the dynamic link
    library USER32.dll.

    Any idea what could be happening?

  2. I am guessing that you are using a 32 Bit version of Vista. I have seen
    this issue many times now with people upgrading their system. The only
    resolution that has been found is to re-install Vista. I hope you do know
    that 32 Bit Operating Systems can not utilize 4GB of RAM.

    1. your memory is from different brands and may not be COMPLETELY compatible.

    2. you probably need to do an IN PLACE upgrade of vista to refresh the system .

    2. you cannot use the 4gb unless you are running 64 bit version.

    Whoa! You just lost me. 32Bit versions of Windows can utilize 4GB of RAM
    (that is, you can install that much). The problem is that Windows
    automatically reserves a certain amount of the total for use by the paging
    file and video purposes (whether needed or not) so that the user (and his
    software) never really has access to the total amount physically installed.
    The point: IF 4GB are physically installed and properly system recognized
    the user (and his software) will have access to about 3.5GB of it when
    needed which is a lot more than 2GB physically installed will provide.
    Everybody interested in RAM should read these links:

    Secondly, I frankly doubt that another manufacturers RAM is going to exactly
    match and be compatible with the original installation.

    You can install that much, but it won't all be used. 32-bit operating
    systems have a 32-bit (4GB) address space. Some of those addresses
    must be used to access video RAM, BIOS, etc. (The paging file does not
    figure in here, it's a disk file and accessing it doesn't use these
    addresses). See here: http://members.cox.net/slatteryt/RAM.html for a
    discussion.
