This issue happens...well its unpredictable, i could be playing for hours or minutes when this comes up.

Basically my game slows down for a minute, texture maps (of the like you would edit in CS for some games) flash up on screen. I alt tab, re-open the game, and something insanely weird happens.

The screen essentially goes into static, but defined static, so i can see bits and pieces of the game, but the textures are simply gone and the screen strobes of pretty much every visible colour known to man.

However this doesn't just occur on C2 afterwards, i open up Arma 2, BC2, Halo 1, i get the weird static crap but not on the same level as C2. A reboot fixes it but it is rather annoying. I don't know whether its just my GPU giving up or not enough airflow...but this didn't even happen in C1 where it definately DID have a hard time pushing the graphics out.

System specs:
Dell Inspiron 530 Q6600 Quad
Palit GTS250 GPU
3.8GB Ram
Unpatched Crysis 2.

NOTE: Before anyone gets the idea that "oh you've been defending the bugs in the game and now you're complaining, hypcrite/retard/failure (in no particular order)!". I play Arma 2, bug heaven. I'm used to it.
