OK not 100% why but my system just powered off mid game. have to cut turn the power off at the mains before I can restart,

for what temps i managed to check after a reboot were all between 40C - 65C

i do think it is a overheating problem but not got any evidence to indicate where the problem is anyone got any ideas or advice

run a CPU stress test and monitor temps, if under 80 you should be fine. Did you do a clean install of video drivers, google DDU and use that to wipe all old drivers and install latest Nvidia ones.

that's the problem I had a while ago if u remember  and I had to buy a new power supply for my computer

---

It's not drivers I know that and now I'm fairly sure it's not temps after 9 hours of been off only lasted 5 mins I think Phil is probably right or it's a ram issue

what gpu are u running mr t and  how much power does your new garaphic card take       am running a cx750m  power supply

Had more or less exactly the same problem with my previous PC when I upgraded to a new GPU.
Replacing the PSU did the trick. For my latest build I went with a Fractal 1000W, to be on the safe side.
If you can run it long enough to read out the event log, I got messages like "Kernel Failure" or something like that.
At the time I didn't know about this and didn't "connect the dots" but Kernel problems seems to be an indicator.
Anyway, my bet is on the PSU.
Good luck!

Same thing happened to me. It was dust bunnies that had made a home in my power supply causing it to overheat and shut down. A good vacuuming and hair dryer blowing fixed it.

Arte et Marte

download Memtest86 at https://www.memtest86.com/  and run that to check if your ram is the culprit.  if there are no errors then I would invest in a new power supply.  You don't need anything more than  750 watts. You want quality, not quantity.

I recommend Seasonic as a brand. a bit more expensive but most come with a 7-year warranty.  Corsair and Evga supernova series are also good choices.  Good Luck

I had this problem about a month and a half after a new build - heatsink paste or its fan seemed to have dried/died; replaced heatsink and paste (I did a stress test and watched temps via speccy to trouble shoot)

Ok I swapped out the psu and it seemed to work but said it was missing or had corrupted windows files. So I have in plugged the ssd and reconnected my original psu and booted knoppix which for those that don't know is a live os which means it can run from a cd or USB stick. And no had any issue with with loss of power

So my question is could a fault ssd cause the issues I was having

glad its sorted

I don't think it would power off your computer, it would go to BSOD or just black screen. I would run a health check on the drive.
