Possibly you might not be getting enough electrical power or enough cooling. If there wasn't enough cooling from the start (meaning when you got your computer) it could have slowly been destroying your computer's hardware.. Also succesfully you might have a memory hogging program in the backgroud such as iTunes that didn't close properly and may still be running, so make sure minecraft is the only substantial program running. Assuming your using windows go over to the bottom of your screen, right-click, and then click "Start Windows Task Manager" and when it opens go to the "Processes" tab and organize by size. If anything abnormally large and you know what program it is and you think it's safe, Click end processe, do it. BE WARNED UNLESS YOU KNOW WHAT IT IS DON'T CLOSE IT, YOU CAN SERIOUSLY SCREW UP SOME ****.
