Hei there,
I dont know if this alreay has been posted, but its driving me nuts.
Everytime after I played a bit WC3 or WoW (which I quitseveral months ago) my mac does on random screenparts like shown on this picture

On PC that meant my Graphiccard is overheating or going to die soon, since I dont want this to happen to my iMac, what can I do, ist this a Graphic Card issue, or something else ?
