Hey guys.. The story is quite long but I'll try to explain as simple as possible : Oops, forgot the specs : CPU - i7 4770K GPU - GTX 780 WINDFORCE OC RAM - 16 GB Corsair Vengance Pro Series SSD - 128 GB Corsair Neutron PSU - Corsair RM750 Cooling - Corsair H110 Thermal paste photos : http://imgur.com/a/3gmPz Heat readings #1 (win) : http://www.youtube.com/watch?v=13F30feBWhI Heat readings #2 (bios) : http://www.youtube.com/watch?v=moDGnaabQLc I was lucky to win a PC and it came already built. At the first windows boot, everything was ok for the first 10 minutes then my Nvidia Kernel Driver started to crash every 1-2 minutes (exactly when the cpu temp reached 100 degrees celsius). After I tried 10-12 drivers, fresh OS etc, I conceded that the GPU hardware was faulty (false). I went into BIOS to check for factory OCs but everything was on minimal/default. I realized in BIOS that my CPU temp was 91 degrees celsius (first morning boot). I immediately closed the PC and let it chill for 30 minutes. Then I started it again, and went directly into BIOS. The temp went from 72 degrees celsius to a stable 91 degrees celsius in 5-6 seconds. At this point I was quite angry and I realized that I used the CPU at that temp for more than 12 hours. From my pov a CPU would fry at that temp in less than 10 minutes, so I kept the PC running with that temp. I checked the thermal paste. Photos : http://imgur.com/a/3gmPz . I checked if the heatsink actually stays on the CPU without any space between. Also I recorded my readings in HWMonitor/Speedfan/RealTemp/BIOS. I apologize for the foreign accent and bad english. This is my first actual gaming rig and I'm quite the beginner when it comes to building the actual rig. About the thermal paste, I already ordered Arctic Silver 5 kit (remover/purifier/paste) just in case I'll need it if you guys say that the paste that's already applied is faulty and needs changed. My beginner opinion is that it's a faulty heat sensor on the motherboard. The CPU can't be actually at 91 degrees celsius. It would burn to a crisp, and I already used the PC for 12+ hours.
