You know... You can take a screenshot with Windows key + shift + s and not be a nigger and take a picture of your screen.....
Also, if the game is running from the old HDD getting a SSD will help some. I don't see what ram the system has, ram is expensive as fuck all right now though. It's old enough I might have some in a parts bin collecting dust depending on what it uses though. (16 gig is not bad, more is better)
