Here is what I am going to say:
1. Attach to
WUProp. It collects data about the work units you run and helps build an information database about various architectures. It doesn't run on CPU, so it is free credits. I have it on all my machines.
2. Make sure you have updated windows, installed Java, installed the latest NVidia driver, and generally have your machine up-to-date.
3. PrimeGrid: Select
only the PPS Sieve subproject there. Be sure to allow CUDA work units, and deselect CPU work.
4. Pick any other project to run on your CPU (Step 3 will get PrimeGrid running on your video card). And I would say to pick something you like. If you like medical research,
World Community Grid is great. If you like astronomy,
Einstein is a good one. If you simply like credits,
AndrOINC is great right now.
Hope that helps. Let us know what other questions you have. And welcome! Glad to see you up and running!
