PC shut down while playing, heat, driver, or age ?

[Sir cheese]

You must be thinking it's all about the gpu temperature. Well that's what i thought too. I've got a rog GW75V, gtx 660m, windows 8.1. So i cleaned my fans, my gpu with care, started my computer, then playing, and... automatically shut down. It doesn't take too long to shut down. I started monitoring the temperature but i got up to 65°C, which is okay (it can go up to 75°C). Then i tried using a stand with fans on it. Still crashing. The screen sometimes flicker before shutting down...

I downloaded old drivers, nothing new. I might have updated my graphic drivers before it got bad, but then, with the old version it should work.
When i stress my gpu it shut down, yet the temperature is only 65°C, I had a run with 68°C, so it couldn't be the security.

And finally, my pc is 10 years old, it might be the end of his life, I can't tell.

Thanks for reading, have a good day

https://www.asus.com/us/ROG-Republic-Of-Gamers/ROG-G75VW/specifications/ is this what you have ? If so, there is not much you can do, hardware wise. If it were a PC you could try the parts on another PC.
You could test the CPU, GPU, RAM and hard disk/SSD and maybe do a Windows reinstall if everything is fine.

Might very well be PSU / power at this point in time. Shut down / hard power off does sound like that to me if its not temps. Which its not at 70C, not even at 80.

You can test this, somewhat, by reducing GPU power target to 80%. Less performance, but it might just keep going that way. Some other nice tricks if the power delivery is shaky: boot up with opened optical drive (if you can't get past boot), remove HDD / replace with SSD.

Did you plug back all wires/ connections properly? Did thermal paste get to wrong point?

Id contact asus, could be faulty power supply or a overheat.

temps sound ok which points at power supply to me.

Open Event Viwer and look at the Windows System Log ... scroll down the list of events till you see any Yellow (Warning) or Red (Error) messages. Come pack and post the description and detail of any of ths from the time of your crash occurred. Please just those entries not the entire log.

Thanks for the replies, as some said it's coming from the power cable, so I got it changed, and the PC is no more shutting down !
Nothing else, I have to change these boys every 4 years, the trick was the light was still on when the computer was shutting down...

Thanks for your help, enjoy your day !
