Very long loading levels (Medal of Honor Airborne)

Who can knows where the dog rummaged and how to solve it?:
Many years on every OS and many components of this game, but only this year has faced a problem well a very long load, or reload after death. Even on very weak laptop with XP this is not observed. On 8.1 and 10 also no problem. But on 7-ke maximum is not solved. The distribution of 7-Ki is used in different laptops of the same. One laptop, however, is weak, but until 7 it was the 10-ka and 8.1 and the game went well. And the other laptop - games, and loading too tedious. Bust drivers, fizikov etc. did not help. Is it all in the OS?! 7-ka - does not build, net official.
