Hi Chris, try using latest NVidia Drivers. we had such unpredictable 'freeze' problems on systems with Intel Core 2 Dual CPU's , XP with NVidia Driver 158.xx and different NVidia Hardware (G80, G71, G70) etc. . We was wasting a lot of time with bughunting. Typically this problem arised after some minutes ... some hours under WinXP. Workaround was to set affinity to run the app on only one core. But it did not fix the problem. After updating the system to the latest driver 162.xx the problem seems to be fixed. I wouldn't say that all threading issues are fixed with the latest driver release from NVidia, but the 'freeze' problem seems to be history.
