Medievel 2 running slow

[Believil]

Hello
  Can some one tell me why my game (medievel 2 total war) is very slow and some times it stops.  How can i improve this to enjoy the game

Well according to the website, the minimum processor speed should be 1.5GHz but the recommended should be 2.4GHz.
According to your sig, your processor is 2.11GHz. That could be a part of the problem.

For smooth gameplay, I would suggest tuning down the graphic qualities in the game settings.
You could also try defragmenting your hard drive
(Start --> All Programs --> Accessories -->System Tools --> Disk Defragmenter)
