I suggest you "remove games from the equation". Run OCCT (Power-Supply Test option). If that can run for 30 minutes without crashing (or the laptop melting-down) ... then the problem is likely the games ... or hardware is insufficient for those games and/or resolution ... or there is some other software process or service making the computer unstable when "pushed hard".
So I recently bought an XPS 13 9310. It works great for almost everything, but when it comes to games a lot of them crash. I have seen youtube videos of people playing these games on this laptop smoothly, so why won't it work for me? Thanks
