    Suddenly seem to be getting the "NVLDDMKM Video driver stopped responding but has recovered" message.
    This happened a few months back and I reinstalled the NVIDIA driver which cured it until now. Tried the same again -- no luck. It happens ONLY at boot up, never when running, the desktop appears, then can black out for anything from 0.5 to a couple of seconds. I am sure when it comes back it is also a notch down in brightness, like when you switch to battery.
    This time I uninstalled the driver, let Windows find new hardware, which it identified correctly -- GEFORCE 6100 -- and then I tried a new install of the driver version 7.15.10.9755 from the Acer site. Same message intermitantly appears though.
    Question ?? -- What would be the effect of using Vistas own driver instead of NVidia ?
    I see by Googling this it's a common problem, wondered if you guys had any EASY !!! answers.
    Thanks.

    Not something I would normally ever consider but I have done a registry tweak. Found it on the MS techweb sites.
    It involves effectively disabling the error reporting for the graphics card, as it appears that the "not responding" error isn't really an error at all, it's just that the card has fallen outside the 2 second windows allows before Vista resets the card thinking there is a problem.
    Time will tell I suppose. The tweak was,
    [H_KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers]"TdrLevel"=dword:00000000

    the original value was 00000007 (7)
