I have run GPUGrid in the past, have completed WUs, etc. This was with a 182xx driver. I recently updated to a 18585 driver, which stopped working with the error bad driver. I then updated to the latest driver 190.38 (>= 18200)for notebooks, which claims CUDA 2.3 (>= 2.0) and my card has compute capability 1.1 (>= 1.1). So now I get this:

Why can't I get work for this computer? The computer got work with the old driver...

I will recommend you to read news on front page. There was some software changes, which was required CUDA 2.2 hardware & drivers compatibility.
Here is some from news:

"July 25, 2009
The driver required will be at least 185.xx, that is required for CUDA2.2. If 190.xx works for you, you can also install it.

July 25, 2009
All Windows users should update their Nvidia driver to version 190.xx. This driver allows computation also in SLI mode. From next week, we will update the application to CUDA2.2 which requires the new driver. The current application for Windows will still work under the new driver in the meanwhile."

Probably, the reason for such messages could be the fact, that your Quadro FX GPU 1,1 compute capability isn't supported now by project, doesn't matter, what drivers you're using.

My 9800 just quit running GPU work without any change. An update of the 9800 driver to the latest version AND an update to BOINC 6.10.3 makes no difference. I get the "not available for your type of computer" stink even though nothing changed initially, and no u[date seems to help.
