My hp touchsmart 520-1040a "blacks out" whenever playing games like CSGO and Rocket League although I my PC is still running.I have been monitoring my GPUs tempurature and the highest I've recieved is 105c although it is usually at max 90c under stress and around 65c - 70c while idle. I am suspecting broken hardware since my family has had it for around 6 years before we cleaned it.
