Sorry it took few days to get back to this...
I checked out
https://en.bitcoin.it/wiki/Mining_hardware_comparison and a few other sites with info and used the most generalized settings that others where using for nvidia 8800GTS card, but still hangs indefinitely when it says starting.....
Did you install OpenCl drivers for your card? That was the issue I was having (although I am using Scryptminer + Litecoin-qt). I also had to dump the contents of the Scryptminer folder into the Litecoin-qt folder and overwrite the shared files. Hope that helps
I downloaded the latest opencl drivers I could find from nvidia, but still having the issue :/
