Sounds like driver problems. Which video card was in the PC before the 7850? Even if its ATI, you still should uninstall drivers, then run program like Driver Sweeper, and then reinstall new drivers. Or maybe you have to use older drivers. You will have to check the supported drivers for 3dsmax.
I´m having a similar problem with the same video card, Vray RT works with CPU and even CUDA, but only uses CPU; when I switch to OpenCL it freezes, I get the message "VRay Standalone has stopped working"
Have you managed to solve your problem?
The problem seems to be with OpenCL 1.2 compatibility.
Previous cards used OpenCL version 1.0 and 1.1. 78xx has OpenCL 1.2
I have exactly same issue with Sony Vegas rendering. I look forward when Sony engineers release a patch with OpenCL 1.2 support.
