Are you using mods ? I have the same problem with online play...

Hello,

thank you for the response. However, we cannot determine what exactly caused your game to crash. It is necessary you tried to run your Arma without any mods. If the crashes still happen then, please send another crashdumps.

If the crashes stop (on Arma without mods), please try to activate mods one by one until you find out which one causes the crashes.

Mods are not official content from Bohemia Interactive and it is very likely that the CTDs you are experiencing are caused by collisions between two or more mods.

Please let us know, thank you.

Just played Arma without mods, took longer to crash, but I crashed, crashdump:

Hello,
we need rpt, mdmp and bidmp files to perform an analysis, could you please upload all of them?

Sure, just reinstalled windows, full clean system, and I crashed again,
logs of everything:

I'm sure it's not a 'OS' problem, because I clean installed everything, without success, it could be a hardware problem, but it also might be an Arma bug,

Thank you for the crashdumps, I have assigned the problem to programmers.

Thank you very much!, hope to here from you soon!

I found the solution myself.

I found out that my BIOS Drivers were outdated, So I updated them, fixing my problem. maybe a tip to the dev's; Have like a bar in the main menu with a notification if something is outdated.

this can be set as "problem solved"
