Hi everyone,
Everytime I play a game on Steam for a long period of time (25min or so, it varies) and sometimes just 10min of game play, my entire iMac crashes, and then when I reboot the computer I get this pop up message:
My iMac never crashes unless I'm playing a game on Steam, as I've done a test, and if I don't have a Steam game going, my iMac is on 24/7 for an entire week. As soon as I start to play the game for a long period of time, in 30min to an hour, I get the iMac death screen. Any help is appreciated.
