About 4 months ago, I used to be able to run ARMA 3 x64 just fine. However it has begun to crash on startup more a more frequently. At first it was only every 1 in 10 tries it would crash, then it became 1 in 5, and so on until I had to start the game 4 or 5 times before it would run without crashing when it started loading (//sounds like hardware fault - but see below//).
I have spent months researching every solution I can find relating to startup crashes for x64 bit ARMA on the internet and have tried every solution that was suggested. I really can't face reinstalling windows just to run the x64 version of ARMA as it's the only application (//and x64 application//) I have installed that doesn't work as intended).
ARMA 3 x32 works every single time without exception, with or without mods and regardless of any parameter changes// as x64 used to//.
The game will randomly run x64 fine with or without mods and parameters customised (happens about once every 10-20 tries) and once the game is up and running it runs indefinitely without crashing or any issues.
Here are just some of the things I have tried, I can't remember every single thing though:
- -Completely reinstalled ARMA 3 from scratch with no mods or parameter settings
- -Checked my memories health (ram) //memtest// (was fine)
- -Individually tested each of my corsair DDR3 4gb Ram sticks and starting up ARMA each time
- -Underclocked my CPU (GPU has never been OC'd)
- -Updating graphics card drivers & rolling back drivers
- -Verified integrity of game cache
- -Removed all mods
- -Unsubscribed from all workshop content
- -Reset all parameters to default
- -Removed all my profile data
- -changed various values in the registry that supposedly relate to x64 crashes (after x64 ceased to run **not before**)
- -switched to the dev build
- -Tried launching with or without battleye
- -Tried launching using battleeye.exe
- -Creating, removing and editing the nvidia control panel 3d settings for ARMA x64 .exe
- -Reinstalled direct x
- -Uninstalled Visual C++ 2013 Redistributable package (both x86 and x64 version), and restarted my computer etc.
Things I have yet to try:
- CCleaner registry cleaner
- De-Fragment PC
- Run a Windows System File Check tool to repair corrupted system files
- Reinstall Windows 8.1 (absolute last possible option)
