Did you mean laptop? A lot of times people sit there laptops in places that the fans will pull in animal hair,dust etc. The dust & dirt build up and cause it to over heat sooner than it should and even lead to a total break down. Its good to be careful where pc,s are left and that you take time to properly open them and clean them every so often. This helps with over heating. Also make sure if your using a laptop you give it room to breath under it. For example my silly husband puts his old laptop in his lap over a pillow. The pillow ends up hugging it to much while he types and blocks all the air. Then he wonders why it gets so hot so soon! I hope this helps you.
