Unless you're wholly mechanically inept, it should be immediately obvious. If not, you may have bought a graphics card which won't fit your computer... this is particularly likely if you have what's usually called a "compact" case, which requires special expansion cards that are significantly shorter than those designed for a full-sized case.
It's becoming more common for card designers to design cards to fit in the smaller cases but attach a full-sized backplate (the part visible from the outside of the computer). If you have one of these, it probably came with a smaller backplate designed for a compact case; you just need to unscrew the large backplate and attach the smaller one instead.
The bottom line is that if there's even the slightest doubt in your mind, you should take the card and computer to a computer repair shop and pay them to do it for you.
