Standard VGA Graphics Adapter?

I just formated my Laptop and I used to have a ATI Radeon X1200 or 1000.(I'm not sure). Now i have all the same things (32 but, windows 7 ultimate, intel 2 duo, etc…) but the graphics. It showed me Standard VGA Graphics Adapter instead of ATI Radeon X1200. Please help me. Now i can't run games like the Sims 4, Darksiders, Minecraft, or league oF Legends.
