Inno 3d GE Force 4 MX 5200 -- This is your top priority, as the Video Card is where your video memory (ram) is stored. If the game requires 128 MB of video ram/memory... then you have to check if that is what you got.
256MB DDR -- This is your second top priority, your RAM is what allows your computer to store temporary data to be read by a program on the H.D.D... if the program requires x amount of RAM, you should really get more than that... and not the exact amount (as windows needs ram to run in the BG).
Also, if you're running any instant messaging programs... please close them. It doesn't matter if you're giving someone hints for the game in mid-play... you HAVE to close these.
Next, see if you have any internet programs running at the moment (except for Norton products such as Norton Personal Firewall, etc.) close these programs... ESPECIALLY a program like internet explorer. On windows OS's... you can use ALY+TAB to switch from the program you are currently running to another program.
