I am a new member joined today looking at the very helpfull posts. I have Inspiron 5100 laptop and had problems with fan which is not cooling the processor enough. I read some forums regarding Inspiron 5100 fan problems, so I decided to open up and clean the fan. Everything went fine (cleaning) but when I tryied to switch on (boot) the laptop, nothing is showing up i.e., blank screen, no sound. But when I push the power button on, the power light (one of the 3 lights in front) goes on, CD/DVD drive goes on, fan starts and then nothing happens on the screen. Please if anyone can give/provide solution, help much appreciated.
Thanks in advance.
