Plutonium

I hope this is the right place to look for help. I've just recently installed, but immediately I noticed some maps dropping my fps down to 0. One of these maps is Carrier, other maps I cannot remember, I just close my game everytime this happens. Some maps work perfectly, including; Nuketown, Slums, Standoff. I've tried changing to windowed, turning off & on vsync, changing graphics settings. I'm starting to run out of ideas. I shouldn't have any issues actually running the game. Well just the fact that I can play other maps just fine should be enough proof for that. I hope someone has some ideas. Thanks.
