Locking as there is your other post open in a proper forum.
I have a Dell inspiron n7110. Don't use it too often. My brother uses it for movies and Fb and stuff like that. Recently it stopped working and all I could here was the fan running super fast. I assumed it needed to be cleaned so I took it apart, cleaned it and then put it back together. It worked fine when I turned it on. But now it is doing the exact same thing. What should I do
