PC restarting when playing games but not when i'm running benchmark tests

[garmiel20]

Hello guys. I need your help. This problem is bugging me for like a week or so. I have this system unit for almost a year. Previously I had MSI RX 480 then I decided to downgrade to GTX 1050 2GB version. I did not have any problems back when I was using my RX 480 card. Then I had this strange problem when I used GTX 1050.

My pc is restarting when I'm playing games. I tried playing dota 2 on max settings, vsync on, and the pc will restart when the graphics starts to become heavy. Like no BSOD or crash or anything. It just restarts and reboot again. Same goes to Resident Evil 2 Remaster. Right when I started walking on the game (on medium settings) it restarts right away.

Now here's the catch, when I'm running GPU and CPU Stress Test (GPU 100% load and CPU 80~90% load) my pc is NOT EVEN RESTARTING. I've ran multiple GPU and CPU Stress Test and still the pc won't even restart.

Here's what I already done in troubleshooting. Any inputs from you guys will be a big help. Thanks!

- swapped two Power Supplies (still restarting)
- tried my GTX 1050 2GB into other system unit (works fine. No restarting happened)
- swapped RAM Sticks (still restarting)
- applied new thermal paste on CPU (still restarting)
- reset bios (still restarting)
- reinstalled windows 10 (still restarting)
- transferred my files from HDD to an SSD (still restarting)

Specs :

proc: i5 - 3570 (non K)
mobo: Asrock H61m-u3s3
gpu: GTX 1050 2GB Palit
ram: 8 GB Corsair Vengeance
psu: Corsair VS550

Did you ever run ddu to wipe the old and drivers off and install the nvidia ones?

Does DOTA 2 support and are you using DX12?

Hey mate, I'm having the same problem now - did you ever find a solution? It's so frustrating...
Literally only happens with games. Not during any of the card tests also.
