Notebook Operating System and Recovery

I've had my HP Envy for less than a year. I look after it well and rarely take it outside of my home - only once or twice for classes and even then it had a cushioned cover. I only use my laptop for essay writing and university research. The laptop has been overheating - once even burning my leg! - and it melted off the rubber grips on the bottom. Recently I have noticed that the entire bottom part with the keyboard and mouse pad has become completely warped with the mousepad falling down on one side and even some of the keys on the keyboard slanting at strange angles.  Alongside this the screen continually goes black and flickers which is significantly impacting my work. I've been trying to get in contact for a long time to try and see if I can get my laptop fixed but no one has gotten back in contact with me. It is extremely upsetting as I invested in his piece of equipment and it has barely lasted 10 months. I really need help!
