Hi all, new to the forum, and need some help with my pc. I put this computer together two years ago and I have never had any issues with it until now. Basically my computer fully restarts when playing some graphic intensive games, without even giving me a blue screen of death. I have changed the setting to prevent windows from restarting with BSODs but I still don't get one. No dump files are generated by Windows either when I get these crashes. The games include a heavily modded Fallout New Vegas, heavily modded Skyrim, Distance, and F.E.A.R. (only when upscaled x3 using NVidia DSR settings).

Some things to note:
- No recent hardware changes
- No recent drive changes
- Tried running at stock CPU clocks, still crashing
- CPU temps never go higher than 65 C
- GPU temps never go higher than 65 C
- MemTest shows no ram errors, all test passed
- I suspect its either a GPU or PSU failure, however I have not seen any kind of graphical glitches or artifacts to suggest a GPU failure.

Here are my specs:

Power Supply: CORSAIR HX Series HX850 850W
Motherboard: ASUS MAXIMUS VI HERO
Hard drive: SAMSUNG 840 EVO 500GB SSD
CPU: Intel Core i5-4690K Devil's Canyon Quad-Core 3.5GHz OC to 4.5GHz
CPU Cooling: CORSAIR Hydro Series H105
GPU: GIGABYTE GeForce GTX 970 4GB
Ram: G.SKILL Trident X Series 16GB (2 x 8GB)
OS: Microsoft Windows 10

Any suggestion would be greatly appreciated.

Thank you!
 
Have you tested the hardware? Try your video card and power supply in another system, or known good parts in yours. Did you try a clean Windows setup to rule out OS or driver issues?

You said you "tried running at stock CPU clocks" was the system overclocked? Is the video card overclocked? Could have been damage from the OC.

Just wanted to post a quick update in case anyone is having a similar issue. Turns out my power supply was malfunctioning. Once I replaced it with a new one I got no more crashes.
