Hi all, recently i got a second hand gaming desktop with a gtx 980ti, i7 6700k and a corsair h110i gtx as the cooler. Everything was working well for a few months until yesterday. I restarted the my pc and it hanged at the logo screen upon rebooting. After a forced shutdown, everything went to hell. My cooler fan speed was spinning like crazy despite the temps showing 40C for the cpu. After changing some bios settings, the fan went back to normal for a while. However now, the temps go up to 100C during gaming and it's not even full load. It's running at stock 4ghz and everything seems to be normal. The vcore is 1.216V Max and i even undervolt the system by a -0.1V. I didnt overclock anything. I've tried loading up the default bios settings and it's the same. I dont think there's anything wrong with the voltage anymore. I was able to play AC Odyssey which is a demanding game at 80C max before the restart. The desktop was used for 2 years before i bought it.
