Thanks for reply Jerry.

We did install on a clean drive. Just the other day, we indeed did clean and reseat our graphics cards.

We have run some crash reports through FCS Maintenance pack and it seems that there is something weird going on with the graphics cards though. I cannot find what driver version is installed on card (mysteriously missing from system profiler info), but I suspect that the driver is out of date.

Going to update driver to the latest one for snow leopard (10.6.8) for my cards (geForce 8800 gt). Having some difficulty finding which one was the latest one though. Think this could help? I called NVidia tech support for their input, but they were unbelievably unhelpful.
