Solved

PC restarts when playing video games.

Low requirement games never has any kind of problem.
Medium requirement games sometimes do restarts the pc.
High requirement games most of the time restarts the pc.

Strangely some video games with high requirements doesn't make my pc reboot.


So it lasts about less than 2 minutes before the game turns off.

It kinda depends and randomly changes.

Before it worked for 30 minutes.
Then it worked for 5 seconds.
Then now it's about 2 minutes.

Before the game makes my pc reboot. (Shut down everything instantly black screen
as if somebody pressed the power button , then it automatically turns on , on it's own.)


My pc


NVIDIA GeForce GTX 960
Intel Core i7 4790K

I'm not sure how to find the other requirements.

The power supply is enough.
I cleaned the pc.

I have multiple pc temperature softwares however most seems to have some problems
telling the truth.

Example.

1 of the software says it's crazy hot but then I search if that's a problem, then people are saying
it's ok. That should be that software's problem. like a bug.
Using 1 of the software says 127C is this ok ? and it was probably tom's hardware where another guy asked a question and said it was ok.

Changed my power supply unit after being broken once.
It's like about just an year.
Do power supply units always break so fast ?

Does it happen if you use the pc for high graphics gaming for long and
move large files like 10gb for a long time ? 80mb per second.

  1. the problem might be cooling, 127c is very high for your cpu. maybe your fans are running fine. the way i see it, your system(probably cpu) is reaching these extreme temps and is shutting down to prevent any damage to the cpu. check if all you fans are running when playing games. and the temperature reading that you provided, is it your case temperature, cpu temps or gpu?

    No programs are running with my pc right now.

    With the software called SpeedFan.

    It says

    Gpu 41C
    System 45C
    CPU 128C (Fire emoticon means hot right ?)
    AUXTIN0: 39C
    AUXTIN1: 114C (Fire emoticon)
    AUXTIN2: 109C (Fire emoticon)
    AUXTIN3: 18C
    HD2: 35C
    HD0 97C (Fire emoticon)

    I'm not even running any programs and it's hot ?
    Isn't this false ?


    With other softwares. it's always 30~40 degrees
    TMPIN5 is 127C 260 though.

    In the task manager, it doesn't say anything is running besides firefox which is taking the most memory.

  4. how long has your computer been on before you checked the temps? from what i can tell it seems like your cpu fan isnt running.

    It hasn't been too long since I turned the pc before checking the temperature without turning on any programs.

    I opened the case and checked the fan for the graphics card and the cpu.
    Both are running.
    I turned the video game and both were still running. However it had to reboot again.

    I also tried moving more dust. When my pc was already clean enough.

    in that case..it could be a failing thermal probe in the cpu..maybe try bringing it to your local pc shop? or if you or your friend has another cpu that fits in the same socket, try swapping the cpus to see if there is a change. if you are still using the same cooler and you are getting cooler temps, it is the problem with your cpu.
