Yes, that’s the information I was looking for. The Operating System line doesn’t show the Service Pack 1 (for reference, that line from my dxdiag information is Operating System: Professional 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.130828-1532)). You can get Service Pack 1 here. Try installing SP1 and see if that helps with this issue.
