i dont know anything about durons, but if its anything like the athlon, there souldnt be 3 little things. oh, except for the little rubber things on the top. that keeps the heatsink off the CPU. if those come off, it can very well be a problem. all the heat is comming off ur cpu, onto the heatsink and back to the cup. it couldhave also damaged the cpu. if you can get a pic of the 3 little things, it would probally be easier to figure out
