Hello, was on my laptop the other day and it just shut off and made a weird hiss noise like something was burning and smelled of burning. I just took off the plate on the back and smelled around and seems like it is coming from around where the ram is. Only way to really look is to actually take the whole thing apart and look but I don't want to if i don't have to. Would ram cause it to not be able to turn on or could it be the motherboard is burned or something. By the way this is a Lenovo g50-70.
