Hi :)

In the past 2 months, my PC has been restarting itself when playing any demanding game. It suddenly shuts down and turns on, without any BSOD. This can happen 5 minutes after starting the game, or 1 hour after. For example, I can play Overwatch in low settings, but before the problem started I was able to play it in Epic without problems, and now if I try that, it restarts.

PC Specifications (I built it one year ago):
- Motherboard: Gigabyte 970A-UD3P.
- CPU: AMD FX-8370 Black Edition 4.30 GHz.
- RAM: DDR3 GSkill Sniper 2x4GB 1866 Mhz and DDR3 HyperX 1x4gb 1600mhz.
- GPU: GTX 960 4GB GDDR5 EVGA SSC+.
- Storage: HD 1TB Western Digital (64MG) Caviar Blue - SSD Kingston 120gb.
- PSU: 750w Thermaltake SMART.
- Windows 10 Home edition.

I never overclocked anything.

Here you can look a SpeedFan screenshot with the temperatures while playing Overwatch (epic settings), right before the pc restarted (without minimizing the game) -> http://puu.sh/vdBrb/d77d7b07f6.jpg
I know the temps could be lower, but I'm not sure if that's the problem because they were always that high, since I first built it, and it didn't restart before.

I have tried disabling Fast startup and Auto Restart. I formatted the OS, installing all the new drivers for everything. I ran Memtest86 (no error). Cleaned hardware. Checked if PSU wires were correctly connected.

I checked Visor events in Windows and I have several "Critical Kernel power id 41 task 63, Bugcheck Code 0" in the times when my pc restarted.

My guess is that, while overload, the GPU needs more energy and the PSU is having trouble giving it, so it restarts? I really don't know. How can I know if my PSU is failing?

Thank you, and sorry for the long post :)

I think its due to overheating... try cooling ur system by placing it in a cool room... also check if the fans are working and air flow is perfect... also do clean ur pc by removing the cabinet and cleaning the dust... 0also check if the thermal paste is good...

U may also check if ur psu is working properly....
