Same here, I recently bought the game and its been a nuiscance for me.

However it Only happens when the game eats up all the bandwidth on my HDD. I mean if you look here it tries to pull out over 300MB/s out of my HDD, and if it doesn't drop bellow 200MB/s quickly it crashes and freezes the game immediately.
