Go in the GTXP control panel under the OTHER tab (far right)...
Uncheck Enable hardware acceleration for 3D sounds. You can also go in the Windows Control panel, select sounds and multimedia, audio (middle) tab, advanced tab then performance tab. Bring the slider next to hardware acceleration back a notch at a time and retry the game. Do this until the problem goes away.
As far as any affect, I don't know how it affects other applications but if it stops the STOP crashes, it's worth it. 🙂
