My game freezes randomly during gameplay. The whole system freezes. It doesn't respond to keyboard or mouse actions. I can't manually kill the process via Taskmanager either, because the whole system is unresponsive. I can still hear sounds and talk to my friends on Teamspeak, though. The only solution is to put the PC into sleep mode via the power-off button and boot it again. Then after logging in I see the error message "Arma3.exe has stopped working".

Sometimes Arma crashes when minimized. If there was a crash report, the last report should be from a freeze during gameplay and the one before it from a crash when minimized for about 5 minutes. {F26304}
