Hey thanks for the reply MrSweet... I have re-done the paste on both GPU and CPU twice now. Upon dis-assembly I inspected my work and it was good - full spread of the paste to the block with a slight amount of extrusion on the sides. All four block screws tightened in proper sequence and torqued nicely. I was very careful to reapply the gel-pads that keep the boards from contacting each other in the right places. But, actually I have removed the GPU card completely and running on the on-board video. It doesn't make a difference. From my observations I would say that either the thermals are wrong or the shut-off table is messed up. Strangely HWiNFO64 thermal readings show ~30oc for CPU thermals. Only the PCH reading shows 47oC at startup but that has never changed. I have read a bit on this measure and I think it is the bottom end of the scale for this thermal sensor. None of the readings ever warranted an overheat event. Even the fans do not turn on at this point, although I have manually set them both to full using the HWiNFO control and they work great. Still shuts down though - Fans or no fans.

I have a m17x R4 that has thermal problem. Its never been mistreated and started shutting down randomly a month after warranty expiration. Removed, cleaned and re-applied thermal compound with Arctic Silver. Cleaned fans and tested - All ok. It shuts off almost immediately after powering up at room temperature. If I take it outside during cold weather (5 degrees C or colder) for 30 minutes it will run fine. Temperatures reported are never over 40C so clearly it is the thermals that are miscalibrated. I would like to try an unlocked BIOS on it so I can remove / increase the thermal shutdown parameters. But the links to these BIOS files/ PRR tool are broken. Any chance of reviving the links or reposting them? Right now I have a very expensive brick.
