I labelled this under cooling because I can't see what else can be doing this. Sometimes I can go a full day without my computer freezing, others, it's more common. I can only presume it's down to heating as it has been doing it since I got it. All drivers are up to date, the computer is almost dust free and I always keep the Graphics Card Drivers the newest version. Here's my temperatures without playing a game. and this is it whilst playing SC2. any advice is heavily appreciated.
