what video card do you have?

 

my suggestions=stop/disable the non-important services...stop all start-up programs...set windows to performance mode....run clean disk...checkdisc....defrag....reboot your computer after each step and let windows load up completly dont rush each step...im sure someone else can give you the details on each subject...good luck and game on!

 

I have a nvida gforce 2 graphics card

 

I would say that with your processor and graphics card with that game
your going to have issues.( I have that game and the specs on the box are not accurate-you need a good system to run that game at default settings)
you may try turning down all the in-game detail settings, overclocking your hardware (if your comfortable with that), adjusting your video card detail and resolution settings.

hope this helps
