Soldiers HARD crashes every time!

Hi,

So I bought Soldiers on Steam, and after about 15 minutes of play time, it ALWAYS hard crashes. It's running great and I'm having a good time, and all of a sudden it freezes and my PC just reboots.

I'm running a Core 2 Due MacBook Pro with Windows XP SP3 with the newest drivers. I know there are patches for Soldiers that *might* fix this issue, but I can't install them on the Steam version of the game.

Does anyone know of either a fix for this, or any method I can use to install the Codemasters patches in the hopes that they may fix things?

Thanks!
