How to switch my video cards?

Hello all, my laptop is Acer aspire 4810T , my video card is SUPPOSED to be radeon 4330, but when I use can you run it, it gives me that it's intel series(4)series express, so which one is actually running ? I'm afraid games are reading the other vga card (Fifa07 isn't running and my laptop can run it very well, supposed to), so please I would appreciate if you can solve this to me (The fifa part most importantly, my laptop got 3GB of ram, and a 1.4 core2 solo processor while fifa needs only P3 to run :S )|||Install catalyst control center / drivers. If you can open CCC up, then its using the radeon.
