I recently acquired Call of Duty 4 from a friend (for free I might add) because wouldn't run on his computer. Well, his computer is fairly new, and it baffled me why it wouldn't run. So after a couple hours of searching the internet, I came across this website
. When you select the game from the drop down menu and click the "Can you run it?" button, it will review your computer's specs. and list rather the game is compatible with your computer or not. It will show the recommended specs. and the minimum specs. to run that specific game. And if the game isn't compatible, it will show what components you need to upgrade to run the game.
