I had the same problem with my current GeForce 210-I solved the problem by installing the 197.13 Drivers, and have been using them ever since-the 275.33 drivers just caused my screen resolution to go all fuzzy and put me into 4-bit color mode. That's right, 4-bit.
On a second note, how is your graphics card branded? For example, MSI sells an "MSI GeForce 210" that is based on nVidia's technology and is therefore reliant on nVidia drivers, or at least nVidia-based Drivers.
