ForceWare 196.75 Can Kill Your GeForce Card!!!
NVIDIA has removed the latest ForceWare 196.75 from their servers because this driver has an important bug: it prevents the fan from spinning and caused a death of multiple graphics cards around the world.
G92-based graphics cards (GeForce 9800GT, 9800GTX and GTS 250) seem to be very affected by this bug.
I currently use this driver on a EVGA GTX 295 / Win7 64-bit without issue.
So in case of doubt, NVIDIA recommend to use ForceWare 196.21. But this driver has a bug and prevents the overclocking of GPU
So the recommended driver is the ForceWare 196.34.
Le jour se lève et les conneries commencent
R196.75 were also the source of artifacts in my OpenGL apps. See HERE for more details.
