My PC stopped working from out of sudden. No BIOS, no BEEP, nothing.
After checking all components OK, the last piece of the puzzle had to be the CPU (Intel Core i7-6700K) so I ordered a new mainboard and a new CPU.
The new mainboard + CPU arrived, have been installed and everything is working fine again.
Having the CPU laying around on my desk, I played around with it, and noticed, that the substrate looked somehow bent. I compared it to the CPU socket and the "dents" in the substrate perfectly match some plastic spacers of the socket 1151.

Searching for "Skylake bent" on the internet, brought my attention to this site: Skylake: Kühler können Sockel-1151-CPUs beschädigen
I suspect that the cooler (be quiet! - DARK ROCK PRO 3) bent the substrate of the CPU over the course of 2 years until it failed.
The components involved:
- CPU: Intel Core i7-6700K
- Mainboard: ASUS Z170-A
- Cooler: be quite! DARK ROCK PRO 3
- Case: be quiet! Silent Base 800
The PC was assembled by me in October 2015 and broke down in November 2017. It was never moved, transported or physically abused (which would explain such a deformation).
Be aware of this issue if you use a heavy CPU cooler like the be quiet! DARK ROCK PRO 3. I will try to reach out to be quite! to see if there have been reports of those kind of incident.
