This is my computer type. It is Toshiba Satellite M40/M45 SeriesCan i change the graphic card of this computer? And how can i put it in?
Sorry.

Call of Duty 4 is a VERY graphics intense game.

You will not be able to play it in that laptop, and you cannot upgrade the graphics.



If you still want to play the newest games in a laptop, then get one designed for gaming like this:

Sounds like a laptop. If it is, you can't.
Sadly no... until recently there have been almost exactly zero laptops that have upgradeable video cards, and even now it is only possible on high end ones.
Go to the video card manufacturer site, Windows Update (choose Custom) or http://www.driverguide.com and see if there is an updated driver for the card. Most games do not run with 16 bit video.



If the driver does not help, visit the Toshiba website to see upgrade options.
