Hey guys. Most recently my copy of Arma III has been crashing a lot, usually within 5-10 minutes of gameplay. I have just discovered two other titles which were running fine doing the same IF I leave them idle without any input (ie, keyboard, mouse), this seems to be tied to the fact that somtimes, perhaps 1 in 10, my system decides it doesnt want to wake up from 'sleep' mode. The crash consists of the game sound playing a few seconds then freezes, screen usually turns black with fragmented graphics last seen in game, before going completely black. A reboot is always required, ctrl alt delete does not work. My system specs are as follows: Operating System: Windows 7 Home Premium 64-bit with Service Pack 1 BIOS Date: 07/12/12 11:28:38 Ver: 04.06.04 Processor: AMD Phenom(tm) II X4 965 Processor (4 CPUs), ~3.4GHz 7970HD 3gb GPU 990FX Extreme 4 Memory: 16384MB RAM Available OS Memory: 16380MB RAM DirectX Version: DirectX 11 So far I have tried a memory test (single pass) with the windows diagnostic tool, came through clear. Checked for virii/malware, seems safe/clear, and cant see any reason why it wouldn't be. Installed/Uninstalled audio and graphics driver(several times). Opened up my rig, given a good dose of compressed air. Reinstalled games in question, checked integrity in Steam. Monitored temps in both CPU and GPU, both seem to be at acceptable levels. I am really at a loss of what I should try next, I am getting extremely frustrated, I pray some wisdom here may guide me to a working rig once more!
