I had a similar problem to this, I took it to the shop, they ended up
replacing the MB. They tried various things, couldn't make it work .
Couldn't tell why the heat sink would not maintain good contact.

I just realized this heatsink is anodized ( or whatever the term is )
and so was the last one , let's hope the 4 rubber pads on the CPU are
actually electrodes. Well Al foil to the rescue.
Now that I said that, it seams that I have read about foil in the context
of installing heatsinks.
Hmmm...
