Hello, my sister's Acer is not very good at handling things that should be fairly easy. It shuts down during streams of Netflix and games of Minecraft and League of Legends. It runs at very high frames no problem, but for only about 10 or 15 minutes. Streaming Netflix in HD only lasts about an hour. I installed "CoreTemp" and never read that high of temperatures, only about 75 when shutting down. We used compressed air to blow out dust that builds up in the fan and it had only a placebo effect, I guess. The warranty is run up so we can't bring it to be fixed either. During the process of shutting down, it runs at 60 frames but then runs down to about 2 or 3 frames and then, poof, shuts down. Any ideas on what might be causing this to happen?
