Friend of my parents got this message on her computer and was advised by geek squad to buy a new computer. I was asked to setup her new computer so I did. In sitting down at the computer I moved the old computer and noticed the rattle and then found out what happened to it. I figured I could fix it and then she could give it to her church. Looking inside it's obvious where the heatsink went. I aligned up the markings and used thermal adhesive to put it back on the board. The message still comes up though. Anyone know what's going on?
