I'm a newcomer to the whole bitcoin concept, and I'm having a bit of trouble getting the software to detect my card!
On my PC I have a phenom II 955 and a GTX 560 Ti - in GUIMiner, the only device that appears is "AMD Phenom(tm) II X4 955", and when I click "Start mining", the bar along the bottom of the window reads " NVIDIA CUDA |Starting...", and doesn't change. I have tried clean installing the latest drivers from NVidia, to no avail.
I decided to see what it came up with on my laptop (running an i7 2630 and a GTX 460M), and surprisingly the only option in GUIMiner is "GeForce GTX 460M". I have installed nothing more graphics driver-wise on my laptop than I have on my PC, both overall drivers having been installed recently - doesn't make sense to me how an earlier card is detected and a later one isn't!
Thanks in advance for any support,
