Anyone have any problems when they OC such as the title says? If I leave it at stock level I can get into any game, play it for hours on end without a problem. Now If I overclock it to medium standards, it's ok unless I get into a lot of action going on at once. What it will do is the sound will hiccup the screen will continue for 3-5 seconds as the sound hiccups, and then the system powers down. Does that sound like a) overheating b) running out of juice c) something else?
