Thanks i went ahead and tryed puting the hsf on but ran into trouble with those push pins. I got it in with much swearing but I'm afraid, because that last pin might pop out sometime because it did it once already. I'm hoping i just didn't have it in all the way in that first time. I would like to go ahead and try it but I'm afraid if it pops up again i won't notice it and i will have a problem. What would it hurt if it popped up again? Would the cpu just get to hot and the comp shut off? Would there be any permanent damage to the chip? Could i just wait for that first shut down and then replace it?
