Hello, i recently built myself a PC for 1080P gaming
Ryzen 3 1200 clocked at 3.7 GHZ
Sapphire RX570 nitro+ OC (1340 MHz)
ASRock ab350m mobo
RAM 2x8 GB Micron oc@2666 MHz
PSU Chieftec smart gps-600a8
Case Gamemax g561-f blue (3 fans)
All games run on Samsung Evo 860 250GB

Problem: After playing games for around 30 minutes or less my PC freezes and i can only hard restart it, i tried troubleshooting by giving more voltage to CPU, reset clocks on RAM but it did not help, i used benchmarks like AIDA-64, Furmark, Unigine Heaven, Cinebench, ran them at max details and everything worked fine, (Aida, furmark, gpuz, ran them for 45 minutes and no errors). But when i try to play GTA V or Mafia 3 my PC freezes.
After rebooting i hear GPU fans spinning very fast for ~2-3 sec.

I have latest drivers for Chipset, Graphics, Bios/Uefi.

Below is a image when my PC froze, as you see temps are quite good, plus i play with VSync.
Thank for your recommendations.

Since GTAV stresses your CPU a lot, I would try to reset overclock and see if the problem persists.
What voltage is your CPU at?
I would also figure your power supply could be the culprit. I have heard of Chieftec power supplies being decent for OEM computers, but for a card like an RX570, it may not be a great combo.
Although Chieftec says that the PSU is over 80% efficient, it is not 80+ certified at all, and there is knock off 80+ branding on the website. Not something I would trust.

This PSU might be the culprit. Replace this power unit asap, and grab yourself some high quality PSU model from reputed/known brands like SEASONIC, EVGA, CORSAIR, ANTEC, FSP, BE QUIET, just to name a few
 
But playing other games works fine, for example, Dota 2, Borderlands 2, CSGO, just in GTAV i get this problem
Dota 2, Borderlands 2, and CSgo are older titles that are easy to run on most hardware. These titles would not stress your system much as GTAV. GTAV will demand more from your system, which could cause instability on a bad OC or bad PSU, even if it doesn't show in easier to run titles.

RN i reset OC on CPU and got it to stock, and played for about 2 hours, my pc did not freeze, i think it was the main problem, now i will try to find a clock speed that will not crash my system
