At times I have good luck with the ARMA 3 platform, but at other times it will give me a "Memory Read Error" which locks up my ability to get a screen capture, but once I clear this I get "0xC0000005 - Status Access Violation".
I have an iBuyPower pc which plays all my other games reliably, and at times will play ARMA 3 for hours, but frequently it will give me the error described above just as I'm entering the game.
I have updated my PC's BIOS, chipsets, video drivers/software, along with swapping out my memory DIMMs and running extended Memory Diagnostics. {F27876} {F27877}
