    Asus M3A76-CM
    AMD Phenom x3 Processor
    2 gigs DDR2 PC6400 memory

    No Video through S-Video output in windows.

    I have just upgraded my MB and Video Card on a computer I use as an arcade machine.
    I need the output to go to a Television through S-Video

    The problem is odd because I can see the bios loading and even the "Loading Windows XP Loading bar across the screen on the TV, but once Windows starts the screen goes blank.

    Steps taken in preinstall:
    I removed all the display drivers prior to installing new hardware and after the install, started the computer with monitor and installed the new Nvidia drivers.

    Trouble shooting steps and results:
    I tried to verify the TV connection but the Nvidia Control Panel will not find my S-Video TV connection, only the VGA is found. I connected the TV and restarted but the TV could still not be found in the Display properties or the NVidia Control Panel. :confused:

    1. I Connected the VGA connection while the screen was blank on S-Video output.
    The screen DID display on the VGA connection.

    2. Loaded windows into Safe Mode.
    While loading drivers before safe mode comes up, it hangs at gagp30kx.sys
    but continues to load after a while. The display shows on the television in safe mode. (y)

    Additional information:
    After doing a bit of research I found out that the gagp30kx.sys
    is a Via AGP driver.Could this be the source of my problem? I no longer am using AGP, maybe windows is also loading my old AGP and trying to display to the AGP slot that is no longer there???

    3. I Went into the BIOS and made sure that the PCI express card was the default card used.
    Result: none. (n)
    When loading windows regularly, it still could not display to the S-Video connection on the monitor.

    My questions are as follows

    1. Does windows need to still load the gagp30kx.sys file when using PCI-E?

    2. Is there a way to verify that all AGP drivers are removed even though none display in Hardware Manager or Dxdiag?

    Any other help would be appreciated Thanks! :D

    You could try to clean up leftover drivers with

    Driver Cleaner Professional
    Nasty File Remover

    But once Windows has loaded, the card is pretty much under the complete control of the NVidia drivers. The connection needs to be configured there. Where did you get your NVidia driver?

    I got them from the nvidia website.
    I didn't want to use the CD because usually the most up to date drives are on the website.

    exact address and drivers:

    GeForce/ION Driver Release 190 WHQL
    Version: 190.38
    Release Date: July 21, 2009
    Operating System: Windows XP, Windows XP Media Center Edition
    Language: U.S. English
    File Size: 80.6 MB

    at the moment I am running sfc /scannow hopefully it finds and replaces a windows file that is causing this...
    At this point I am pulling at straws..

    ok after a bit more TS I think I found where at least i need to look.
    I removed all drivers using the tool you recommended. Thanks!
    the computer came up and used the TV as needed
    then after I reinstalled the graphic drives I had the same problem...

    Luckily I had the same kind of card in another computer that is by another manufacturer.
    I just didnt want to take apart.
    they both are running the exact same drivers
    I will refer to the cards as such
    "Palit" is the suspected problem card in the "arcade" machine.
    "PNY" is the card in my "bedroom" computer

    I tested the PNY on the bedroom machine that it was currently in.
    works perfect displaying to the television

    I then swapped the two cards
    now I tested the PNY in the arcade machine and I have the exact same problem.
    then I tested the Palit in the bedroom computer and it works fine.

    This points to the new mobo on the arcade machine.

    I then updated the BIOS on the mobo.
    result same problem...

    can you recommend anything else?

    Thanks for your help in advance

    Sounds like you've done a good job of trouble-shooting. It could be as simple as one bad connector on the non-functioning machine. But if you have a warranty, it's time to use it.
