I take it that you are using a laptop when you mention Geforce Go 5200. Not the best thing to use for a gamer. The GF go 5200 is pretty minimal when it comes to gaming cards. I would recommend packing as much ram as possible into the machine, shutting down all unneeded processes and programs that are running in the background, and lowering the game's graphics settings to the lowest settings. Check the graphics settings in CMOS to see if you can dedicate more memory toward the graphics card. That is just about all you could do for gaming issues with a laptop.
