I also get lots of graphical artifacts and sometimes hard crashes(having to reboot to get my PC working again) when I try to play Arma 2 or DayZ on my desktop PC. My speccs are: Mobo: GA-X58A-UD3R (rev. 2.0) CPU: i7 930 @stock clocks GPU: geforce GTX 570 12GB RAM If this had happened in other games as well I would assume that the GPU was dying due to overheating, but it doesn't. I've monitored the temps during attempts to play Arma, and they are normal. Never even reaching 70C. I've scoured the internet in search of solutions to my problem and tried many proposed fixes related to graphical issues, but no luck.
