[Crash] My game crashes whenever a server changes maps.

[Kommandant Rockwell]

I originally couldn't load Kobura so I went through the normal trouble shooting and verified the game, deleted the folder in my games, reinstalled et cetera. Upon reinstall I have a new host of problems and have tried all the previously mentioned but reinstalling again and I can't load any maps when the server is changing them. Here is my dxdiag so you can see any relevant information about my PC: http://pastebin.com/H0aG4rtW. Any help would be appreciated, thanks.
