Need some unrelated to LoL advice from hardware techs

So I bought my computer last year, it's a Dell Inspiron 15 3000 series and had no problems with it the whole year, until now. The keys I use the most (Q W E R A S D shift space tab esc) are loosening up and the keys (W A D E) are constantly coming off. I've shown this to my teacher that seems to understand abit and says there is absolutely nothing wrong with the keys nor the supports. Everything's intact and nothing is broken. This is a huge problem because day by day the keys are coming out more and more, and it's only a matter of time until other keys (Q, R, shift space tab) start coming out aswell. I want advice from someone who has experienced this kind of unpleasant experience.
