*sigh*
It needs to be law that any laptop you buy that isn't expressly made for gaming must come with a gigantic sheet at least as big as the box that says, in plain huge red letters:
YOU CAN'T PLAY MODERN GAMES ON THIS ************ BECAUSE IT'S NOT MOTHERFUCKING MEANT TO PLAY MODERN GAMES.
Not exactly pointed at you, OP, but I feel like I see this thread at least twice a day. It's more pointed to everyone who tries to play the big new games on $500 laptops and wonders why they won't work at all. If they did, $1500 laptops wouldn't be necessary at all.
Oh, yes. Reasoning. What you have, my friend, is something called an onboard chip, sometimes called integrated graphics. It's simply a GPU (Graphics Processing Unit) that is soldered onto the motherboard. It takes its resources from other places - namely, RAM and the processor - and uses those to render graphics. This is fine for, say, getting on the internet or typing word documents or watching a movie, but it will not work for graphics-intensive activities such as modern games because it isn't fast enough. It's actually quite slow. Sure, you could play Half-Life or Morrowind or something of that sort on it - those games are old and don't require much - but even if you get Skyrim running it will chug at an unplayable rate.
For comparison, my Toshiba with a decent processor (an i3 at 2.23 GHz) and 4GB of RAM has one of the better chips, Intel HD Graphics. The best I can run is Portal 2 at low settings, and that's because it's running on a fairly old engine. I'd be willing to bet that your computer is a fair bit weaker than mine.
