Question Hardware issues while gaming and OCCT results

Sep 16, 2020

I have this rig;

  • Gigabyte B450M DS3H
  • GSKILL Flare X 16GB (2x8) DDR4 3200Mhz CL16
  • Cougar CGR-GS-750 GX-S 750W 80+ Gold Power Supply
  • XFX - AMD Radeon RX 5700 XT RAW II 8GB GDDR6 PCI Express 4.0 Graphics Card
  • Kingston A2000 500gb 2200/2000mb/s Nvme M.2 2280 Pcıe Ssd (Sa2000m8/500g)
  • Amd Ryzen 5 3600 3,6ghz 35mb Cache
I play Wow, Fifa and Fm. Unfortunately i am having problems while playing any of them.

My computer constantly freezes briefly while playing Wow.

I am getting DXGI ERROR DEVICE HUNG error while playing Fifa. (sending screenshot)
Fifa Crash

I deleted my gpu driver with DDU and reinstall it but it didn't work.

I just need to understand which component is broken so i started to run OCCT tests.

CPU Test = Crashes in 2 seconds
Linpack = No problem
Memory = OCCT freezes as soon as i push start button :)
3D & VRAM = Run smoothly
Power = Crashed in 3 seconds

I hope it is not about my GPU since XFX asked me to ship it to Hong Kong. The shipment cost is almost equal to GPU price.

As you can understand my English is not that good. I apologize for any mistake i have made.

Thanks in advance for any help.
