directx error

 I have this problem:

DirectX function "GetDeviceRemovedReason" failed with
DXGI_ERROR_DEVICE_REMOVED ("The video card has been
physically removed from the system, or a driver upgrade for the
video card has occurred. The application should destroy and
recreate the device. For help debugging the problem, call
ID3D10Device::GetDeviceRemovedReason."). GPU: "NVIDIA
GeForce GT 555M ", Driver: Unknown. This error is usually
caused by the graphics driver crashing; try installing the latest
drivers. Also, make sure you have a supported graphics card with
at least 512MB.
