G2 white screen & choppy sound
I don't know if this is the same problem I had or not, but if G2 is starting with just a white screen after the program loads, try turning off the fog. Whenever I install or reinstall G2 on my XP, the fog is always on after the first start of the program. Kinda stupid I think for fog to be set on as default. As far as the sound, I can't help there.
Good Luck!
