Opening Renders

When I try to open a render in Photoshop I can get an error message saying "NVIDIA display driver files different (incompatible) versions of the driver have been detected.

NVIDIA OpenGL acceleration is disabled in order to maintain system stability."

But I can copy and paste renders with backgrounds, but I'd prefer not to have to manually make my own render -.-

If anyone knows where I can upgrade my graphics card that would great ^_^
