Hi 2byts, hopefully that's the answer but we'll see... Bad drivers can always be a problem but this is the first time I've heard of a sound driver that's so bad it messes up the video driver as well.

If that does solve it, you can reset the moi.ini settings back to their defaults which are:

DisplayThreadLimit=
StaticBufferMaxVRAMToUseMB=

those being just blank, and then

GraphicsAPI=Auto

Hope that will work!
