Help with frames

Yesterday when I logged on, my graphics were entirely reset for no reason. I switched them back to what I think I had them on before. But all day yesterday and today my game has been having supreme frame drops. The number one priorities to me are skin textures and frame rate. I really don't care about anything else. I have the latest NVIDIA drivers. I don't know much about computers, but this is the laptop I use.
