[QUOTE="chscag, post: 1157700, member: 46727"] Mac computers are designed to shut down if they overheat. This is of course to prevent damage to the CPU and other components. I don't know if that's what your iMac is doing as there are other things that can cause a shutdown. Power supply, or bad memory for example. Before doing anything else... if your iMac is still under warranty or if you have apple care, take it on back to the genius bar and have them go over it again. Since it's so close to Xmas, it may be difficult to get an appointment right away. In the meantime, you might want to monitor the temperatures inside your iMac and the rotational speed of the fans. You can download istat menus from [URL="http://www.islayer.com/apps/"]here[/URL] or smcFanControl from [URL="http://www.macupdate.com/app/mac/23049/smcfancontrol"]here[/URL]. Also, check your system logs when the shutdown occurs to see if there is anything that stands out. [/QUOTE]
