An overheating motherboard will still turn on while it's hot, it'll just turn itself right back off again. Is that what's happening, or does it just stay completely off?
It shuts off and the power button doesn't work on the pc, I unplug the power cable, everything and put it back in and hitting power doesn't do anything. The motherboard lights are on but the whole rig is non-reactive.
Then after about 5-10 mins, it just suddenly turns on and boots itself up. This same type of thing happened once a few months ago when I tested overclocking for GTAV, so I figured the motherboard overheated and got rid of the overclocks and then never had a problem for the next 50 hours. But now this is happening constantly.
However, I can stop this from happening by manually setting my gpu fans to 50-60% and it keeps all the temps about 10C cooler and there hasn't been any shutdowns so far.
What's weird is really seems related to overheating, yet the temps aren't ridiculously high. I mean the gpu fans are running near silent at like 30% because the gpu itself doesn't even think it's critical hot and needs to turn up the fans. Why would the motherboard be shutting itself down when it hits 70C or a GPU hits 80C? Makes no sense.
And if it's a power supply or grounding issue why would it only happen when temps get high for a while?
The power supply is just whatever gaf recommends in the hardware thread for a 850watt SLI build. Not sure off the top of my head.
