Hey guys, looking for some creative troubleshooting help here.
I've got a rig I built last November. i7-6800k cooled by a NZXT x62, Corsair 3000MHz RAM, overclock to 3.9 GHz.
It's been running fine on all range of tasks, including some server tasks that would max out all cores for hours on end. I ran it for a few hours on a task that maxed out a single core. Seemed fine. Then it just shut down.
Now when I load bios, it's reporting all sorts of weird frequencies: 2.2 GHz, 2.9, etc. It's also reporting CPU temp of 100ºC. I can boot windows but not linux, and even that only lasts for a minute before it shuts down.
I removed the overclock, tightened the x62 (it wasn't loose, but worth a try), flashed the bios. All to no avail. The outbound tube on the x62 is warm when it's running, so the x62 is carrying some heat at least. I'm planning to swap in a different cooler tomorrow, but that's not much of a long term solution.
What other things can I try to troubleshoot? What happened? And how do I make sure this doesn't happen again?
