Recently, my laptop has been acting up. When I push the start button, it forst does a 10 second delay, then tge CPU fan doesn't go as high as a normal boot. It will stay on,but no display, the all the lights go out, but come back after awhile. I have a lot of experience working on computers, as i build a lot, but this is far out of my league. I believe it is the HDD, as i feel no movement, compared to my other laptop and desktop. Please post if you have any ideas.
