Thanks for the link, it is very helpful. My driver is indeed too old,
173.14.15 . Also, since this graphics card has 256 MB memory which is
also shared with normal display windowing, I'm now not sure if using its
GPU for computations would cause my display to die.
VMDCUDANODISPLAYGPUS maybe not useful since this card is the only
graphics card in this computer. Anyway, I'll leave it as CUDA-disabled
for now. Thanks very much again.

Cheers,
Soo Mei
