DayZ crashing after a few minutes of playing.

[Turtlbeef911 0]

"Instruction at X referenced memory at 0x000000XX. The memory could not be read." Thats the error I get ever time I try and play any DayZ mod, its truly annoying it used to happen instantly whenever I joined a server but know it waits a little bit before crashing. Ive tried everything i found on the internet to fix it and nothings worked, I even installed an extra 4gbs of ram cause I thought bad ram might of been the problem but looks like its not. Please help :/ thanks!
