Updating from CUDA 1.0 to 1.1

I’m running a Dell Inspiron 1520 laptop with a Geforce 8600M GT with windows XP. I recently upgraded from CUDA toolkit 1.0 to 1.1. I uninstalled 1.0, rebooted, installed 1.1, rebooted again, and then tested the installation using the Histogram 64 code sample, which promptly exited stating “There is no device supporting CUDA”. Same code works perfectly in 1.0.

I tried installing the updated NVIDIA driver (169.21), but the installer immediately exited with the message
“The NVIDIA Setup program could not locate any driers that are compatible with your current hardware. Setup will now exit”

Any pointers?

please try the steps just posted http://forums.nvidia.com/index.php?showtopic=58191 and let us know if that works for your Inspiron 1520.

Yep, it works now, thanks!
