My System is about a 2 years old...never had a problem with it up until now! The problem seems to happen generally when the game is under a resource load, ie gfx, ram and CPU under stress (intense action). I've tested the ram with Memtest 86 3 passes no errors. Cleaned and checked all the connectors....under load the CPU is running at 46-50C which is good.
