    Hi Guys,

    Recently upgraded the graphics card in my brothers 7720G to the 9600M GT 1GB DDR2(VG.9PG0Y.007). It was a simple and straightforward upgrade.

    I'm creating this thread after following advice from

    http://forum.notebookreview.com/acer/508054-acer-aspire-7720g-graphics-upgrade-3.html

    without avail for loading the drivers! I upgraded the graphics card today and it boots into fine, I'm able to select the correct resolution which is perfect, however it's a " Standard VGA Graphics driver".

    I've tried searching for modded drivers at laptopvideo2go.com - downloaded various packages and each time i run install, I get the "no suitable graphics devices found".

    I have downloaded drivers for various Acer laptops with the 9600m GT 1GB without success, even the drivers from nvidia direct and the same problem persists.

    Any ideas? :(

    Did you try downloading latest driver form Nvidias site?
    I think that might solve the problem...
    You may download it here:
    NVIDIA DRIVERS 258.96 WHQL

    Note that the driver form above link is for windows vista and windows 7 32-bit...

    It's not enough to download the package from LaptopVideo2Go; you also need to download the modified INF file for said driver package, and copy it into the extracted driver directory.
    That modified INF will break WHQL certification (bye-bye Blu-ray playback), but it will allow that driver to be installed on just about any Nvidia system.

    Hi,

    are there any remainders of the old VGA drivers left? Perhaps getting rid of these does help.

    Or - worst case - there is something wrong with that VGA card.

    Try a driver sweeper in safe mode. Then restart your laptop in normal mode, and it will detect the new gpu again. Probably again with standard vga drivers. Then go to the nvidia website, and download original drivers (latest you can get). Install them, your system will reboot and then continu with the installation. And tadaaa, you will be fine. I had it also with my gpu upgrade, and it only took me 5 min to solve this!

    EDIT: You can download a driver sweeper here: Driver Sweeper

    Hi everyone,

    I did the same thing as Mystical Sound, except mine being a 7720 (not the 7720G). Didn't need to but followed the same guide, the vbios was already on the card.

    My problem is that the bios doesn't recognize the video card (no boot-up Nvidia blabla stuff & No 1gb vmem in bios).
    But it does boot though, with standard graphics adapter...

    Any suggestions anyone?
    Because i am seeing myself, in the near future, diving into some hex vbios editor nightmare with directions from some "evil" guide and the "psycho" movie soundtrack, ( wii, wii, wii, wii [not refering to nintendo, btw] ), on the background...

    thanks in advance,

    Mithat
