So as the title says, my laptop has an overheating problem. I've had it for about a year, and recently when I've tried to play games, it'll go soothly for the first fifteen minutes or so, and then get horribly choppy to the point where I'm watching a slideshow. This is quite aggravating, so I installed RealTemp, and it's recording temps of about 74C when I'm just browsing the internet, and up to 116C after a bit of gaming.
So, do I need a new GPU? Do I just need to clean out my fan/heat sink? I'm a bit cautious about opening this laptop up because I'm not the best with computers, but I'd be willing to give anything a shot.
