ye I'm afraid you won't be able to run it properly soopakewlchick .
I looked at the specs of your system and well to be honest it's kinda outdated.
I doesn't meet the minimum requirements of the game so I don't think you will be able to run it properly...
If you do want to play it, I would recommend getting more RAM, in your case your motherboard only supports up to 2GB DDR RAM so I would get 2GB.
And you would certainly need a new videocard aswell, the one you have now is an onboard videocard and well they aren't really designed to play games. If you would play it with this one you would get lots of LAG.
EDIT: If you're not really sure about your pc specs, install this program called Everest. It's great it will tell you everything about your pc components and you will also be able to see the temperature of your motherboard, cpu, GPU, etc...
