Whenever I play any 3D games, after about 15-20 minutes, my computer will start stuttering accompanied by a buzzing noise through the speakers and then suddenly completely freeze, forcing me to restart. I've tried cleaning it for dust, updating GPU drivers and resetting BIOS settings to default but nothing helps. I don't think it's overheating since I tested it with FurMark and it got hotter than it does when gaming but no buzzing or freezing. Anyone know what might be wrong?
Thanks in advance.
