Ok, first of all thank you for all your replies. To Waycoolio and hamblue, I backed the overclock down to 3.8ghz, yes I understand that overclocking increases heat and the stock heatsink is not recommended or else you'll fry your CPU, I don't believe I'm having a CPU overheating issue, and I'm monitoring using RealTemp to monitor temperatures the best I can (when system reboots I try to enter bios to check temp, at time of reboot usually somewhere between 45c and 50c). No my ram is not overclocked, the specs are 1600mhz and my motherboard is reading 1333mhz unless I'm missing something. I am going to use the EVGA Precision X tool too back down my video card as well.
@ SVEN, I bought the game and it came on a disk, it is not currently linked with steam. It was originally 1.1.0.9, I updated it to 1.1.1.1 and today I plan on following all your advice and will post an update after that today sometime. I backed my NVIDIA drivers down from the latest version to the one previous version in hopes that it was more stable. I also checked my Direct X drivers and all other available drivers for the computer system. Last night I ran both ARMA II and DCS A10 and both issues still remain the same however when DCS Crashed (causes whole system to reboot) the BIOS reported supply surges detected during the previous power on ".Asus anti-surge was triggered to protect system from unstable power supply unit "power supply surges detected during the previous power on." I'm running a Kingwin 750w PSU, I don't think I have so much going on that I'm maxing out the power supply. On a forum for that they reported that the unit might be supplying too much power causing the board to believe it's unstable. I'm unsure, and even if it was then it doesn't reflect my ARMA II issues, even though last night when ARMA II crashed my Track IR Crashed before then I was unable to remaximize the screen. Sorry if I'm ranting, I'm trying to describe my problem as detailed as possible so that everyone has the best understanding of what's happening. Looking in my uninstall program right now I see Microsoft Visual C++ 2008 Redistributable - X64 9.0.30729.17 and another line with 9.0.30729.6161 Crashes are just in single player, if I run a quick mission approx 15-30min of flying. In training 5-15min.
Thanks again for every ones input.
