Facing problem with medal of honor 2010 game..?

My pc configuration is AMD 2.4 quad core processor,2 GB RAM,1GB inbuilt Nvidia Graphics Card with ASUS motherboard..I installed medal of honor recently.It is not running properly.It is running in a slow motion.As per the game requirements written I guess there shouldn't be any problem with the configuration.I am playing Call of Duty MW & MW2 in the same PC.Earlier I faced the same problem with COD-MW 2 but later I solved it by changing the screen resolution.But It is not helping in Medal of honor.Please help..I visited "can you run it" the result was pass.
