I had a Lenovo Z51-70 80K600VWIN of which discrete GPU (AMD R9 m375 4GB GDDR3 75W TDP) died. I should mention that laptop is poor quality for its price and hardware. Soft aluminum and plastic exterior.
The time it died I had AMD Crimson 16.11 and Windows 10 1607 14393. The dGPU ran pretty hot because of the poor cooling solution by the OEM. It had two thin and wide copper heat pipes that were attached to both CPU & GPU and exhausted with a 45mm fan I believe.
So my question is, could W10 14393 or AMD Crimson 16.11 somehow have killed the GPU?
Note: Laptop BSOD'ed or crashed whenever dGPU was enabled in the BIOS and ran fine off the iGPU (when the dGPU was disabled). The dGPU is confirmed dead. Combinations between various OS'es and video drivers did not work, what did work was reflow the GPU by heating the board in oven. dGPU worked for a week, died again. I bothered not to do that again and finally sold the laptop.
