Random crashing?

[Exo_Kopaka]

After an hour or so when plyaing, for some reason, my game would lock up and freeze. I would have to use task manager and abort the program.

If I started it up again, it would screw up after an hour or so: it would show the graphics loose all their textures and colors, as if it were just the model itself made of clay, and because of this, I could predict whether or not it would crash a few seconds later, which in turn, it did.

If it would be my third startup, it would crash after a little longer than most of the time, but it only occurs if I turn and look at a large portion of the map, or if I look at a battle of some sort that has a lot of particles and objects.

For some reason, when I check my computer performance in the game, it would show the FPS well over 700. I don't understand how this is even possible.

My computer reaches all the system requirements, just that for some reason, it would just screw up and crash when I am in the battlefield after an hour of playing. Has this happened to you? How do I fix this problem?
