So I got my computer around 3 years ago, and it works just fine on sites that do not require things like adobe or java, but in places like YouTube and on gamesites my computer makes a lot of noise and usually shuts down around 30 minutes afterwards it shuts off by itself. I called a computer expert and he said to let it rest for a few days, so I left it off for a week, and when I went back on YouTube and watched a few vids it shutdown again this time in a shorter amount of time. So I'm wondering should I get a new computer.
