It could be your screen or mother board that is spoilt, maybe you can try connecting the laptop to a external screen and see if theres anything? Before it was unable to boot up did it drop or anything?
No, it was not dropped. When trying to boot up, there is no beep or clicking, and the hard drive indicator light is not on. I am assuming that the problem is either hard drive or motherboard, but I don't want to just start changing things.
