I'm an avid gamer and recently dropped my laptop. Prior to this incident, I could run games fine. Now, within approx. 2 minutes, my entire system shuts off. There's no warning of overheating but I don't hear the normal sounds the cooling fan makes when playing games. It may sound rudimentary so I apologize, but I'm not technologically savvy. Is it recommended that I purchase a separate cooling fan for my laptop or should I take it to a professional for further inspection? Websites/videos/common browsing is not a problem.
