How to replace a heatsink and fan

  1. I have a compaq presario SR1010NX. When I upgraded my computer to Vista, the pins holding my heatsink/fan on top of my processor broke. I have to place my tower on it's side in order for the fan to be running. When I place it upright, the cpu shuts down and the fan doesn't work. As long as I have it on it's side, it will work perfectly. I have another compaq presario that was recently given to me (tower only no monitor or keyboard), but it is a model S4020WM, and I don't know if I can use the heatsink/fan on my motherboard. Also, I would like to know if the processors in the computers are interchangable..any help would be greatly appreciated..

    You need to buy a new Socket mPGA478 heatsink and fan. These are pretty inexpensive, so try a website like or Make sure that you get one that is suitable for the Celeron 2.8GHz processor (it will tell you the suitable CPU's on the listings).
