Hi. I've tried multiplayer four times now, and three of those times, after 20-30 minutes, the PC has rebooted. This doesn't happen with the single player Arma 2 game or other multiplayer games. I'm trying to work out if the reboots I get are down to me or Arma 2. My PC runs Orthos and Memtest86+ for over an hour until a controlled shut down, and 3DMark06 a couple of times in a row. I have seen the sticky but I'd first like to know if the fault is likely to be my set up or the game. Thanks
