I would suggest going to the BETA forums and do some reading. Currently the GPU app is in BETA and still being worked on. There is a forum to post problems for each BETA release. They will also ask for more details like what the error code was, OS version, BOINC version, drivers version, etc...

Check out Knreed's post on compability....your card is generally only 1.1 compute capable. However, as I noted in other forums some cards from various OEM's may have different specs then listed on nVidia's website.

I've a 310M which shouldn't get HCC-NVIDIA tasks and a 9600M GT which is currently not labeled as 'not supported' even though all other 9600 cards are off-limits.

Nevertheless, both cards get continuously HCC-NVIDIA tasks which run 2 seconds and then fail with computational errors.

Why are those tasks send to blocked cards and should be the 9600M GT on the list of not supported cards as well?
