Hello, my old acer aspire one netbook keeps overheating, the CPU idles around 50C and can get into the low 70s before it crashes, so I took it apart and put it back together and now the screen isn't working. It's just black. Did I possibly damage the cable for the screen when putting it back together? It's an odd cable, it's like all cloth and it's taped to the motherboard. And about the CPU overheating, would it be reasonable to apply new thermal paste? I have some arctic silver 5 lying around, or does it require special paste? Many thanks.
