Was having frequent crashes and had heard the realtech sound system could be related. I turned off hardware sound acceleration in dxdiag and didn't have another crash while playing for a couple of hours. Seemed to have fixed the problem. Weird thing is, I went back to dxdiag to verify my information before I posted and the hardware acceleration is back on full. Don't know what to make of that...
