Please, please, please help!! Every time I play Operation Flashpont on my PC, it's ok for a while then the sound & voices of the men become slow & sluggish just like they've been out on the booze all night. This is closely followed by a blue screen crash telling me something to the effect that physical memory dump is now complete.... blah blah blah system cache. When I operate the game with sound disabled it seems not to do this. I have an ASROCK board with onboard sound card. Any ideas?
