Computer Randomly Shuts off, not overheating, and not during benchmarks.

benwaddi16925 · Apr 4, 2018

My computer keeps randomly shutting down. I first noticed this first when playing fortnite today and when ever I would join a new match it would randomly shut down. I looked this problem up and most suggest that it a component overheating or the power supply fan not working, this doesn't make sense as when I run a benchmark or a stress test and my cpu goes past 75C nothing happens but when I load a match or open a program it has a large chance of randomly crashing. It's crashed 3 times when loading into a fortnite match and twice when trying to open the benchmark. But it has never crashed in the middle of a benchmark (The two I've tried is Superposition Benchmark and Cinebench) I noticed in speccy the temps never get above 80 so I highly doubt anything is overheating. This just happens with not warning. Ican't tell if it's because my PSU fan isn't spinning because it doesn't spin under small loads, but this cause wouldn't make sense because it doesn't crash in the middle of a benchmark or stress test. i am using the Asus Dual Intelligence Processor 5 program that uses this chip on my MOBO to "5 way optimize" my hardware. Thanks in advance!

This doesn't make sense to me please help

My Specs:

PSU: Corsair HX 750

Mother Board: Asus Z97-A

CPU: i7 4790k 4.00 GHZ
- Cooler: SHADOW ROCK LP

RAM:

Slot 1: Kingston 8192MB (DDR3-1600)
Slot 2: G.Skill 8192 MB (DDR3-1337) - XMP 1.2 - P/N: F3-1600C9-8GXM

GPU: NVIDIA GeForce GTX 970 (GM204) @ 135 MHz

I have 2 sticks of mixed DDR3 RAM one of which I enabled XMP to clock the G.Skill Stick to 16000MHz in order to have them running at the same clock speed.

Well for me the computer just shutting down is usually 1 of 2 things.
1. Overheating, be sure all vents are clear and you have a clear path for air to travel in the front of the case and out the back and/or top. I take my case out and blow all the dust out every summer with my air compressor.
2. Bad power supply, could be your power supply is dying. If you have another you can try that is an easy way to see if that is the issue.

Power Supply is Corsair and not old at all so that doesn't make sense
And I'm not getting any high temps from speccy

Hey I bought a brand new top of the line TV set and it worked one day and died, I returned it and the replacement worked until I donated it many years later. You can never tell with electronics.

Yes but speccy is reporting very low temps and it can survive benchmarks

Found the real solution, the 24 pin connector on my MOBO was slightly loose, I don't think it will happen again, but if it does this might not be the issue.

That is good news you don't have to replace anything. I love a happy ending!
