At the end of the day I had decided to fix the heatsink issue in my Compaq Presario myself. Around 4 o'clock, when Esme went out to do some shopping I asked her to buy thermal grease at the Steren shop, and a small bottle of isopropyl alcohol to remove the old thermal grease.

Thanks Peter.
I used tie wraps at first to keep the heat sink in place so I could contact HP via their online support. After I had been told that it's not their problem I decided to use a more secure method of keeping the heat sink in place, although I wonder if it's really needed when one doesn't use the on board graphics (like me).
I have no idea how long the heat sink has been hanging on one clip before I discovered it was not in place.
By the way, is it the same motherboard?
I'll email you about the photos, I like to host them.

Great tutorial of the right way to do it! Not wanting to push my skill level (and admittedly doing it half-baked), I simply fashioned a spring out of heavy wire and bent it in a way to push the heatsink up against the North Bridge by hooking the ends of the wire under the case flanges.
I padded the portion of the wire where it rests on the heatsink. I held the ends of the wire in place by - what else - bits of duct tape! I have photos of this (actually pretty neat), but don't know how to upload them here.
We'll see if it works, or just sets the whole thing on fire (or shorts it all out when it slips down - but it's in there pretty tight.)
