Texture bug in PR

[Haji with a Handgun]

The Pictures speak for themselves. I have this texture bug exclusively on insurgency maps, and its completely random. All the textures will wig out and I wont be able to see.

SPECS:

Processor:AMD dual-core 3.0 ghz
GFX: NVDIA 7600
2gb physical ram, 8gb virtual
Not sure about the motherboard

These graphical errors look like artifacts to me, have you checked your temperature while playing, that could be the problem (insurgency is normally more "heavier" for the system than AAS)
