ATI Drivers and CODE 43 error

Discussion in 'Windows Vista Hardware' started by Isaac \Pliqui\ Abouganem, Jun 29, 2006.

  1. Hi all, i'm having troubles with my ATI drivers both for vista x64 and x86,
    tested both version (running now x86), after installing the latest beta
    drivers from ATI, appear the name of my card, Radeon 9550 with the
    exclamation mark and got this message "Error code (43Windows failed to
    initialize drivers (or similar) in device manager". If i use the XP drivers
    i got my both card (secondary too), can switch to better resolution but
    can't use Aero cuz that is not a LDDM compatible drivers. Any one know
    something about this?

    My specs

    AMD Athlon x64 4200+ x2
    3Gb Ram
    Giga-Byte Mobo k8nsnxp-939
    Giga-Byte Radeon 9550 256 mb

    I have the same problem ati x1600 pro 512 meg the only driver that works is
    from the original cd and since it is not wddm no aero/glass the interesting
    thing is that the windows driver wddm cannot start error 43 I still do not
    have the gaming graphics recognized

  3. I saw in some post that the issue was the AGP to PCI brigde, in my case
    NVIDIA nForce3 250 AGP Host to PCI Bridge. Since i'm using a nForce 3 250
    chipset, the nvidia drivers for vista only came with audio and ethernet, no
    chipset. So i use the XP driver wich recognized it but still nothing.
    This is the forum where is saw that and i know i saw another one talking
    about it

    "Ok, found out the problem was with my AGP controller. I got it to work
    using the XP SP2 mode then reinstalled the ATI drivers.

    Now it is working."

    If anyone know about this pls

    I'm assuming he reran nvidia's xp driver setup using compatibility mode. In
    explorer, right click on the nvidia setup file, go in to "properties" and
    then "compatability" checkmark compatibility mode and set to "xp sp2"
    compatibility, then run the file. Then try the ati drivers.

  5. I read in a forum something about that, that the guy who did it worked but
    everytime he shutdown or restart get a lil memory dump blue screen error,
    but worked... i did it and now i got the blue screen error and guess what?
    it's not working lol... Damn Murphy's law

    I will do a clean instalation of vista and do that... but the drivers once
    you got them installed the package doesnt install it, says your files are up
    to date and do nothing... will do this weekend, so i will tell you guys in a
    few days

  6. I installed the Nforce 3 250 chipset in XP SP2 compatibility mode, meaning
    the AGP to PCI brigde were updated, now none driver is working, the old xp2
    one who was working but without aero and the vista beta...
